Python dateutil parser parses wrong number of seconds - python

Python dateutil is parsing strings correctly except for the seconds component of the string.
In [1]: from dateutil import parser
In [2]: parser.parse("05/09/2016 16:04.18")
Out[2]: datetime.datetime(2016, 5, 9, 16, 4, 10)
dateutil.parser is parsing 16:04.18 as 16 hours, 4 minutes, and 10 seconds, when it should be 18 seconds. What's going on here?

Parser doesn't know how to interpret that last non-standard portion of the time. The . instead of a : throws it off. Try using parser.parse("05.09/2016 16:04:18") instead.
You could also try using the datetime module instead since it can be customized with a mask to handle any date and time format.
from datetime import datetime
date_object = datetime.strptime("05/09/2016 16:04.18", '%m/%d/%Y %H:%M.%S')

Human readable delta time text to Python `timedelta`

I have seen many examples on how to parse a human readable text containing a date/time to datetime structure or even seconds since "Epoch".
A few Pyhton libraries (e.g. parsedatetime or dateparser claim to be able to parse relative date/times (like "1min 47 seconds ago") but the end result is always anchored to a specific date/time.
Example using two mentioned libraries:
sdate="1 min 37 seconds ago"
dateparser.parse(sdate)
datetime.datetime(2019, 8, 19, 17, 20, 29, 325230)
pdtCal.parse(sdate)
(time.struct_time(tm_year=2019, tm_mon=8, tm_mday=19, tm_hour=17, tm_min=22, tm_sec=49, tm_wday=0, tm_yday=231, tm_isdst=-1), 2)
What I need, though, is something as simple as a timedelta object, but from what I could learn, the best I can do is to compute the timedelta by subtracting the parsed datetime from current time.
Obviously, this is not the same since I will be adding a sampling error (datetime.datetime.now() is running at a different time as the parser run).
So I ask, is there a simple yet relieble way in Python to parse this delta time text directly into a timedelta object or a scalar value (e.g seconds count)?
Thanks!
There is a way to specify "anchor date" in dateparser using settings:
In [1]: from dateparser import parse
In [2]: from datetime import datetime
In [3]: anchor_date = datetime(2020, 1, 1)
In [4]: parsed_date = parse('1 min 37 seconds ago', settings={'RELATIVE_BASE': anchor_date})
In [5]: parsed_date - anchor_date
Out[5]: datetime.timedelta(days=-1, seconds=86303)
Using the same date as relative base and in delta calculation ensures precise results.

Convert odd timestamp with offset to UNIX time in Python [duplicate]

This question already has an answer here:
Converting string with UTC offset to a datetime object [duplicate]
(1 answer)
Closed 9 years ago.
I have a timestamp string from a web log that looks like this:
10/Jun/2005:05:59:05 -0500
It like to convert it to a UNIX timestamp.
A datetime can be converted with time.mktime(datetime.timetuple())
According to the datetime docs, datetime.strptime() should convert it to a datetime:
from datetime import datetime
datetime.strptime("10/Jun/2005:05:59:05 -0500","%d/%b/%Y:%H:%M:%S %z")
At least on with Python 2.7.2 on my Mac, this results in
ValueError: 'z' is a bad directive in format '%d/%b/%Y:%H:%M:%S %z'
After reading many questions on SO about that error, I decided to try python-dateutil:
from dateutil import parser
parser.parse("10/Jun/2005:05:59:05 -0500")
That didn't work either:
ValueError: unknown string format
Now what?
You can use dateutils to make the converstion, you will need two steps:
>>> import calendar
>>> from dateutil.parser import parse
>>> d = parse('10/Jun/2005:05:59:05 -0500', fuzzy=True)
This will create a datetime object
>>> d
datetime.datetime(2005, 6, 10, 5, 59, 5, tzinfo=tzoffset(None, -18000))
And to convert it to UNIX timestamp:
>>> ts = calendar.timegm(d.utctimetuple())
>>> print ts
1118401145

How to convert a timezone aware string to datetime in Python without dateutil?

I have to convert a timezone-aware string like "2012-11-01T04:16:13-04:00" to a Python datetime object.
I saw the dateutil module which has a parse function, but I don't really want to use it as it adds a dependency.
So how can I do it? I have tried something like the following, but with no luck.
datetime.datetime.strptime("2012-11-01T04:16:13-04:00", "%Y-%m-%dT%H:%M:%S%Z")
As of Python 3.7, datetime.datetime.fromisoformat() can handle your format:
>>> import datetime
>>> datetime.datetime.fromisoformat('2012-11-01T04:16:13-04:00')
datetime.datetime(2012, 11, 1, 4, 16, 13, tzinfo=datetime.timezone(datetime.timedelta(days=-1, seconds=72000)))
In older Python versions you can't, not without a whole lot of painstaking manual timezone defining.
Python does not include a timezone database, because it would be outdated too quickly. Instead, Python relies on external libraries, which can have a far faster release cycle, to provide properly configured timezones for you.
As a side-effect, this means that timezone parsing also needs to be an external library. If dateutil is too heavy-weight for you, use iso8601 instead, it'll parse your specific format just fine:
>>> import iso8601
>>> iso8601.parse_date('2012-11-01T04:16:13-04:00')
datetime.datetime(2012, 11, 1, 4, 16, 13, tzinfo=<FixedOffset '-04:00'>)
iso8601 is a whopping 4KB small. Compare that tot python-dateutil's 148KB.
As of Python 3.2 Python can handle simple offset-based timezones, and %z will parse -hhmm and +hhmm timezone offsets in a timestamp. That means that for a ISO 8601 timestamp you'd have to remove the : in the timezone:
>>> from datetime import datetime
>>> iso_ts = '2012-11-01T04:16:13-04:00'
>>> datetime.strptime(''.join(iso_ts.rsplit(':', 1)), '%Y-%m-%dT%H:%M:%S%z')
datetime.datetime(2012, 11, 1, 4, 16, 13, tzinfo=datetime.timezone(datetime.timedelta(-1, 72000)))
The lack of proper ISO 8601 parsing is being tracked in Python issue 15873.
Here is the Python Doc for datetime object using dateutil package..
from dateutil.parser import parse
get_date_obj = parse("2012-11-01T04:16:13-04:00")
print get_date_obj
There are two issues with the code in the original question: there should not be a : in the timezone and the format string for "timezone as an offset" is lower case %z not upper %Z.
This works for me in Python v3.6
>>> from datetime import datetime
>>> t = datetime.strptime("2012-11-01T04:16:13-0400", "%Y-%m-%dT%H:%M:%S%z")
>>> print(t)
2012-11-01 04:16:13-04:00
You can convert like this.
date = datetime.datetime.strptime('2019-3-16T5-49-52-595Z','%Y-%m-%dT%H-%M-%S-%f%z')
date_time = date.strftime('%Y-%m-%dT%H:%M:%S.%fZ')
You can create a timezone unaware object and replace the tzinfo and make it a timezone aware DateTime object later.
from datetime import datetime
import pytz
unware_time = datetime.strptime("2012-11-01 04:16:13", "%Y-%m-%d %H:%M:%S")
aware_time = unaware_time.replace(tzinfo=pytz.UTC)
I'm new to Python, but found a way to convert
2017-05-27T07:20:18.000-04:00
to
2017-05-27T07:20:18 without downloading new utilities.
from datetime import datetime, timedelta
time_zone1 = int("2017-05-27T07:20:18.000-04:00"[-6:][:3])
>>returns -04
item_date = datetime.strptime("2017-05-27T07:20:18.000-04:00".replace(".000", "")[:-6], "%Y-%m-%dT%H:%M:%S") + timedelta(hours=-time_zone1)
I'm sure there are better ways to do this without slicing up the string so much, but this got the job done.
This suggestion for using dateutil by Mohideen bin Mohammed definitely is the best solution even if it does a require a small library. having used the other approaches there prone to various forms of failure. Here's a nice function for this.
from dateutil.parser import parse
def parse_date_convert(date, fmt=None):
if fmt is None:
fmt = '%Y-%m-%d %H:%M:%S' # Defaults to : 2022-08-31 07:47:30
get_date_obj = parse(str(date))
return str(get_date_obj.strftime(fmt))
dates = ['2022-08-31T07:47:30Z','2022-08-31T07:47:29.098Z','2017-05-27T07:20:18.000-04:00','2012-11-01T04:16:13-04:00']
for date in dates:
print(f'Before: {date} After: {parse_date_convert(date)}')
Results:
Before: 2022-08-31T07:47:30Z After: 2022-08-31 07:47:30
Before: 2022-08-31T07:47:29.098Z After: 2022-08-31 07:47:29
Before: 2017-05-27T07:20:18.000-04:00 After: 2017-05-27 07:20:18
Before: 2012-11-01T04:16:13-04:00 After: 2012-11-01 04:16:13
Having tried various forms such as slicing split replacing the T Z like this:
dates = ['2022-08-31T07:47:30Z','2022-08-31T07:47:29.098Z','2017-05-27T07:20:18.000-04:00','2012-11-01T04:16:13-04:00']
for date in dates:
print(f'Before: {date} After: {date.replace("T", " ").replace("Z", "")}')
You still are left with subpar results. like the below
Before: 2022-08-31T07:47:30Z After: 2022-08-31 07:47:30
Before: 2022-08-31T07:47:29.098Z After: 2022-08-31 07:47:29.098
Before: 2017-05-27T07:20:18.000-04:00 After: 2017-05-27 07:20:18.000-04:00
Before: 2012-11-01T04:16:13-04:00 After: 2012-11-01 04:16:13-04:00

In Python, how do you convert seconds since epoch to a `datetime` object?

The time module can be initialized using seconds since epoch:
>>> import time
>>> t1=time.gmtime(1284286794)
>>> t1
time.struct_time(tm_year=2010, tm_mon=9, tm_mday=12, tm_hour=10, tm_min=19,
tm_sec=54, tm_wday=6, tm_yday=255, tm_isdst=0)
Is there an elegant way to initialize a datetime.datetime object in the same way?
datetime.datetime.fromtimestamp will do, if you know the time zone, you could produce the same output as with time.gmtime
>>> datetime.datetime.fromtimestamp(1284286794)
datetime.datetime(2010, 9, 12, 11, 19, 54)
or
>>> datetime.datetime.utcfromtimestamp(1284286794)
datetime.datetime(2010, 9, 12, 10, 19, 54)
Seconds since epoch to datetime to strftime:
>>> ts_epoch = 1362301382
>>> ts = datetime.datetime.fromtimestamp(ts_epoch).strftime('%Y-%m-%d %H:%M:%S')
>>> ts
'2013-03-03 01:03:02'
From the docs, the recommended way of getting a timezone aware datetime object from seconds since epoch is:
Python 3:
from datetime import datetime, timezone
datetime.fromtimestamp(timestamp, timezone.utc)
Python 2, using pytz:
from datetime import datetime
import pytz
datetime.fromtimestamp(timestamp, pytz.utc)
Note that datetime.datetime.fromtimestamp(timestamp) and .utcfromtimestamp(timestamp) fail on windows for dates before Jan. 1, 1970 while negative unix timestamps seem to work on unix-based platforms. The docs say this:
"This may raise ValueError, if the timestamp is out of the range of
values supported by the platform C gmtime() function. It’s common for
this to be restricted to years in 1970 through 2038"
See also Issue1646728
For those that want it ISO 8601 compliant, since the other solutions do not have the T separator nor the time offset (except Meistro's answer):
from datetime import datetime, timezone
result = datetime.fromtimestamp(1463288494, timezone.utc).isoformat('T', 'microseconds')
print(result) # 2016-05-15T05:01:34.000000+00:00
Note, I use fromtimestamp because if I used utcfromtimestamp I would need to chain on .astimezone(...) anyway to get the offset.
If you don't want to go all the way to microseconds you can choose a different unit with the
isoformat() method.

How do I get the current time?

How do I get the current time?
Use datetime:
>>> import datetime
>>> now = datetime.datetime.now()
>>> now
datetime.datetime(2009, 1, 6, 15, 8, 24, 78915)
>>> print(now)
2009-01-06 15:08:24.789150
For just the clock time without the date:
>>> now.time()
datetime.time(15, 8, 24, 78915)
>>> print(now.time())
15:08:24.789150
To save typing, you can import the datetime object from the datetime module:
>>> from datetime import datetime
Then remove the prefix datetime. from all of the above.
Use time.strftime():
>>> from time import gmtime, strftime
>>> strftime("%Y-%m-%d %H:%M:%S", gmtime())
'2009-01-05 22:14:39'
from datetime import datetime
datetime.now().strftime('%Y-%m-%d %H:%M:%S')
Example output: '2013-09-18 11:16:32'
See list of strftime directives.
Similar to Harley's answer, but use the str() function for a quick-n-dirty, slightly more human readable format:
>>> from datetime import datetime
>>> str(datetime.now())
'2011-05-03 17:45:35.177000'
How do I get the current time in Python?
The time module
The time module provides functions that tell us the time in "seconds since the epoch" as well as other utilities.
import time
Unix Epoch Time
This is the format you should get timestamps in for saving in databases. It is a simple floating-point number that can be converted to an integer. It is also good for arithmetic in seconds, as it represents the number of seconds since Jan 1, 1970, 00:00:00, and it is memory light relative to the other representations of time we'll be looking at next:
>>> time.time()
1424233311.771502
This timestamp does not account for leap-seconds, so it's not linear - leap seconds are ignored. So while it is not equivalent to the international UTC standard, it is close, and therefore quite good for most cases of record-keeping.
This is not ideal for human scheduling, however. If you have a future event you wish to take place at a certain point in time, you'll want to store that time with a string that can be parsed into a datetime object or a serialized datetime object (these will be described later).
time.ctime
You can also represent the current time in the way preferred by your operating system (which means it can change when you change your system preferences, so don't rely on this to be standard across all systems, as I've seen others expect). This is typically user friendly, but doesn't typically result in strings one can sort chronologically:
>>> time.ctime()
'Tue Feb 17 23:21:56 2015'
You can hydrate timestamps into human readable form with ctime as well:
>>> time.ctime(1424233311.771502)
'Tue Feb 17 23:21:51 2015'
This conversion is also not good for record-keeping (except in text that will only be parsed by humans - and with improved Optical Character Recognition and Artificial Intelligence, I think the number of these cases will diminish).
datetime module
The datetime module is also quite useful here:
>>> import datetime
datetime.datetime.now
The datetime.now is a class method that returns the current time. It uses the time.localtime without the timezone info (if not given, otherwise see timezone aware below). It has a representation (which would allow you to recreate an equivalent object) echoed on the shell, but when printed (or coerced to a str), it is in human readable (and nearly ISO) format, and the lexicographic sort is equivalent to the chronological sort:
>>> datetime.datetime.now()
datetime.datetime(2015, 2, 17, 23, 43, 49, 94252)
>>> print(datetime.datetime.now())
2015-02-17 23:43:51.782461
datetime's utcnow
You can get a datetime object in UTC time, a global standard, by doing this:
>>> datetime.datetime.utcnow()
datetime.datetime(2015, 2, 18, 4, 53, 28, 394163)
>>> print(datetime.datetime.utcnow())
2015-02-18 04:53:31.783988
UTC is a time standard that is nearly equivalent to the GMT timezone. (While GMT and UTC do not change for Daylight Savings Time, their users may switch to other timezones, like British Summer Time, during the Summer.)
datetime timezone aware
However, none of the datetime objects we've created so far can be easily converted to various timezones. We can solve that problem with the pytz module:
>>> import pytz
>>> then = datetime.datetime.now(pytz.utc)
>>> then
datetime.datetime(2015, 2, 18, 4, 55, 58, 753949, tzinfo=<UTC>)
Equivalently, in Python 3 we have the timezone class with a utc timezone instance attached, which also makes the object timezone aware (but to convert to another timezone without the handy pytz module is left as an exercise to the reader):
>>> datetime.datetime.now(datetime.timezone.utc)
datetime.datetime(2015, 2, 18, 22, 31, 56, 564191, tzinfo=datetime.timezone.utc)
And we see we can easily convert to timezones from the original UTC object.
>>> print(then)
2015-02-18 04:55:58.753949+00:00
>>> print(then.astimezone(pytz.timezone('US/Eastern')))
2015-02-17 23:55:58.753949-05:00
You can also make a naive datetime object aware with the pytz timezone localize method, or by replacing the tzinfo attribute (with replace, this is done blindly), but these are more last resorts than best practices:
>>> pytz.utc.localize(datetime.datetime.utcnow())
datetime.datetime(2015, 2, 18, 6, 6, 29, 32285, tzinfo=<UTC>)
>>> datetime.datetime.utcnow().replace(tzinfo=pytz.utc)
datetime.datetime(2015, 2, 18, 6, 9, 30, 728550, tzinfo=<UTC>)
The pytz module allows us to make our datetime objects timezone aware and convert the times to the hundreds of timezones available in the pytz module.
One could ostensibly serialize this object for UTC time and store that in a database, but it would require far more memory and be more prone to error than simply storing the Unix Epoch time, which I demonstrated first.
The other ways of viewing times are much more error-prone, especially when dealing with data that may come from different time zones. You want there to be no confusion as to which timezone a string or serialized datetime object was intended for.
If you're displaying the time with Python for the user, ctime works nicely, not in a table (it doesn't typically sort well), but perhaps in a clock. However, I personally recommend, when dealing with time in Python, either using Unix time, or a timezone aware UTC datetime object.
Do
from time import time
t = time()
t - float number, good for time interval measurement.
There is some difference for Unix and Windows platforms.
>>> from time import gmtime, strftime
>>> strftime("%a, %d %b %Y %X +0000", gmtime())
'Tue, 06 Jan 2009 04:54:56 +0000'
That outputs the current GMT in the specified format. There is also a localtime() method.
This page has more details.
The previous answers are all good suggestions, but I find it easiest to use ctime():
In [2]: from time import ctime
In [3]: ctime()
Out[3]: 'Thu Oct 31 11:40:53 2013'
This gives a nicely formatted string representation of the current local time.
The quickest way is:
>>> import time
>>> time.strftime("%Y%m%d")
'20130924'
If you need current time as a time object:
>>> import datetime
>>> now = datetime.datetime.now()
>>> datetime.time(now.hour, now.minute, now.second)
datetime.time(11, 23, 44)
You can use the time module:
>>> import time
>>> print(time.strftime("%d/%m/%Y"))
06/02/2015
The use of the capital Y gives the full year, and using y would give 06/02/15.
You could also use the following code to give a more lengthy time:
>>> time.strftime("%a, %d %b %Y %H:%M:%S")
'Fri, 06 Feb 2015 17:45:09'
.isoformat() is in the documentation, but not yet here
(this is mighty similar to #Ray Vega's answer):
>>> import datetime
>>> datetime.datetime.now().isoformat()
'2013-06-24T20:35:55.982000'
Why not ask the U.S. Naval Observatory, the official timekeeper of the United States Navy?
import requests
from lxml import html
page = requests.get('http://tycho.usno.navy.mil/cgi-bin/timer.pl')
tree = html.fromstring(page.content)
print(tree.xpath('//html//body//h3//pre/text()')[1])
If you live in the D.C. area (like me) the latency might not be too bad...
Using pandas to get the current time, kind of overkilling the problem at hand:
import pandas as pd
print(pd.datetime.now())
print(pd.datetime.now().date())
print(pd.datetime.now().year)
print(pd.datetime.now().month)
print(pd.datetime.now().day)
print(pd.datetime.now().hour)
print(pd.datetime.now().minute)
print(pd.datetime.now().second)
print(pd.datetime.now().microsecond)
Output:
2017-09-22 12:44:56.092642
2017-09-22
2017
9
22
12
44
56
92693
if you are using numpy already then directly you can use numpy.datetime64()
function.
import numpy as np
str(np.datetime64('now'))
for only date:
str(np.datetime64('today'))
or, if you are using pandas already then you can use pandas.to_datetime() function
import pandas as pd
str(pd.to_datetime('now'))
or,
str(pd.to_datetime('today'))
This is what I ended up going with:
>>>from time import strftime
>>>strftime("%m/%d/%Y %H:%M")
01/09/2015 13:11
Also, this table is a necessary reference for choosing the appropriate format codes to get the date formatted just the way you want it (from Python "datetime" documentation here).
datetime.now() returns the current time as a naive datetime object that represents time in the local timezone. That value may be ambiguous e.g., during DST transitions ("fall back"). To avoid ambiguity either UTC timezone should be used:
from datetime import datetime
utc_time = datetime.utcnow()
print(utc_time) # -> 2014-12-22 22:48:59.916417
Or a timezone-aware object that has the corresponding timezone info attached (Python 3.2+):
from datetime import datetime, timezone
now = datetime.now(timezone.utc).astimezone()
print(now) # -> 2014-12-23 01:49:25.837541+03:00
import datetime
date_time = datetime.datetime.now()
date = date_time.date() # Gives the date
time = date_time.time() # Gives the time
print date.year, date.month, date.day
print time.hour, time.minute, time.second, time.microsecond
Do dir(date) or any variables including the package. You can get all the attributes and methods associated with the variable.
>>> import datetime, time
>>> time = time.strftime("%H:%M:%S:%MS", time.localtime())
>>> print time
'00:21:38:20S'
This question doesn't need a new answer just for the sake of it ... a shiny new-ish toy/module, however, is enough justification. That being the Pendulum library, which appears to do the sort of things which arrow attempted, except without the inherent flaws and bugs which beset arrow.
For instance, the answer to the original question:
>>> import pendulum
>>> print(pendulum.now())
2018-08-14T05:29:28.315802+10:00
>>> print(pendulum.now('utc'))
2018-08-13T19:29:35.051023+00:00
There's a lot of standards which need addressing, including multiple RFCs and ISOs, to worry about. Ever get them mixed up; not to worry, take a little look into dir(pendulum.constants) There's a bit more than RFC and ISO formats there, though.
When we say local, though what do we mean? Well I mean:
>>> print(pendulum.now().timezone_name)
Australia/Melbourne
>>>
Presumably most of the rest of you mean somewhere else.
And on it goes. Long story short: Pendulum attempts to do for date and time what requests did for HTTP. It's worth consideration, particularly for both its ease of use and extensive documentation.
By default, now() function returns output in the YYYY-MM-DD HH:MM:SS:MS format. Use the below sample script to get the current date and time in a Python script and print results on the screen. Create file getDateTime1.py with the below content.
import datetime
currentDT = datetime.datetime.now()
print (str(currentDT))
The output looks like below:

Try the arrow module from http://crsmithdev.com/arrow/:
import arrow
arrow.now()
Or the UTC version:
arrow.utcnow()
To change its output, add .format():
arrow.utcnow().format('YYYY-MM-DD HH:mm:ss ZZ')
For a specific timezone:
arrow.now('US/Pacific')
An hour ago:
arrow.utcnow().replace(hours=-1)
Or if you want the gist.
arrow.get('2013-05-11T21:23:58.970460+00:00').humanize()
>>> '2 years ago'
Current time of a timezone
from datetime import datetime
import pytz
tz_NY = pytz.timezone('America/New_York')
datetime_NY = datetime.now(tz_NY)
print("NY time:", datetime_NY.strftime("%H:%M:%S"))
tz_London = pytz.timezone('Europe/London')
datetime_London = datetime.now(tz_London)
print("London time:", datetime_London.strftime("%H:%M:%S"))
tz_India = pytz.timezone('Asia/India')
datetime_India = datetime.now(tz_India)
print("India time:", datetime_India.strftime("%H:%M:%S"))
#list timezones
pytz.all_timezones
To get exactly 3 decimal points for milliseconds 11:34:23.751 run this:
def get_time_str(decimal_points=3):
return time.strftime("%H:%M:%S", time.localtime()) + '.%d' % (time.time() % 1 * 10**decimal_points)
More context:
I want to get the time with milliseconds. A simple way to get them:
import time, datetime
print(datetime.datetime.now().time()) # 11:20:08.272239
# Or in a more complicated way
print(datetime.datetime.now().time().isoformat()) # 11:20:08.272239
print(datetime.datetime.now().time().strftime('%H:%M:%S.%f')) # 11:20:08.272239
# But do not use this:
print(time.strftime("%H:%M:%S.%f", time.localtime()), str) # 11:20:08.%f
But I want only milliseconds, right? The shortest way to get them:
import time
time.strftime("%H:%M:%S", time.localtime()) + '.%d' % (time.time() % 1 * 1000)
# 11:34:23.751
Add or remove zeroes from the last multiplication to adjust number of decimal points, or just:
def get_time_str(decimal_points=3):
return time.strftime("%H:%M:%S", time.localtime()) + '.%d' % (time.time() % 1 * 10**decimal_points)
If you just want the current timestamp in ms (for example, to measure execution time), you can also use the "timeit" module:
import timeit
start_time = timeit.default_timer()
do_stuff_you_want_to_measure()
end_time = timeit.default_timer()
print("Elapsed time: {}".format(end_time - start_time))
You can use this function to get the time (unfortunately it doesn't say AM or PM):
def gettime():
from datetime import datetime
return ((str(datetime.now())).split(' ')[1]).split('.')[0]
To get the hours, minutes, seconds and milliseconds to merge later, you can use these functions:
Hour:
def gethour():
from datetime import datetime
return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[0]
Minute:
def getminute():
from datetime import datetime
return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[1]
Second:
def getsecond():
from datetime import datetime
return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[2]
Millisecond:
def getmillisecond():
from datetime import datetime
return (str(datetime.now())).split('.')[1]
You can try the following
import datetime
now = datetime.datetime.now()
print(now)
or
import datetime
now = datetime.datetime.now()
print(now.strftime("%Y-%b-%d, %A %I:%M:%S"))
Because no one has mentioned it yet, and this is something I ran into recently... a pytz timezone's fromutc() method combined with datetime's utcnow() is the best way I've found to get a useful current time (and date) in any timezone.
from datetime import datetime
import pytz
JST = pytz.timezone("Asia/Tokyo")
local_time = JST.fromutc(datetime.utcnow())
If all you want is the time, you can then get that with local_time.time().
import datetime
todays_date = datetime.date.today()
print(todays_date)
>>> 2019-10-12
# adding strftime will remove the seconds
current_time = datetime.datetime.now().strftime('%H:%M')
print(current_time)
>>> 23:38
Method1: Getting Current Date and Time from system datetime
The datetime module supplies classes for manipulating dates and times.
Code
from datetime import datetime,date
print("Date: "+str(date.today().year)+"-"+str(date.today().month)+"-"+str(date.today().day))
print("Year: "+str(date.today().year))
print("Month: "+str(date.today().month))
print("Day: "+str(date.today().day)+"\n")
print("Time: "+str(datetime.today().hour)+":"+str(datetime.today().minute)+":"+str(datetime.today().second))
print("Hour: "+str(datetime.today().hour))
print("Minute: "+str(datetime.today().minute))
print("Second: "+str(datetime.today().second))
print("MilliSecond: "+str(datetime.today().microsecond))
Output will be like
Date: 2020-4-18
Year: 2020
Month: 4
Day: 18
Time: 19:30:5
Hour: 19
Minute: 30
Second: 5
MilliSecond: 836071
Method2: Getting Current Date and Time if Network is available
urllib package helps us to handle the url's that means webpages. Here we collects data from the webpage http://just-the-time.appspot.com/ and parses dateime from the webpage using the package dateparser.
Code
from urllib.request import urlopen
import dateparser
time_url = urlopen(u'http://just-the-time.appspot.com/')
datetime = time_url.read().decode("utf-8", errors="ignore").split(' ')[:-1]
date = datetime[0]
time = datetime[1]
print("Date: "+str(date))
print("Year: "+str(date.split('-')[0]))
print("Month: "+str(date.split('-')[1]))
print("Day: "+str(date.split('-')[2])+'\n')
print("Time: "+str(time))
print("Hour: "+str(time.split(':')[0]))
print("Minute: "+str(time.split(':')[1]))
print("Second: "+str(time.split(':')[2]))
Output will be like
Date: 2020-04-18
Year: 2020
Month: 04
Day: 18
Time: 14:17:10
Hour: 14
Minute: 17
Second: 10
Method3: Getting Current Date and Time from Local Time of the Machine
Python's time module provides a function for getting local time from the number of seconds elapsed since the epoch called localtime(). ctime() function takes seconds passed since epoch as an argument and returns a string representing local time.
Code
from time import time, ctime
datetime = ctime(time()).split(' ')
print("Date: "+str(datetime[4])+"-"+str(datetime[1])+"-"+str(datetime[2]))
print("Year: "+str(datetime[4]))
print("Month: "+str(datetime[1]))
print("Day: "+str(datetime[2]))
print("Week Day: "+str(datetime[0])+'\n')
print("Time: "+str(datetime[3]))
print("Hour: "+str(datetime[3]).split(':')[0])
print("Minute: "+str(datetime[3]).split(':')[1])
print("Second: "+str(datetime[3]).split(':')[2])
Output will be like
Date: 2020-Apr-18
Year: 2020
Month: Apr
Day: 18
Week Day: Sat
Time: 19:30:20
Hour: 19
Minute: 30
Second: 20
