AttributeError: 'DataFrame' object has no attribute 'allah1__27'

I'm trying to solve this and I'm pretty sure the code is right but it keeps getting me the same Error.
I have tried this:
import datetime
from datetime import datetime as datet
test_df = shapefile.copy()
test_df['timestamp'] = prediction_time
test_df['allah1__27'] = shapefile.allah1__27.astype('int64')
test_df['hour'] = prediction_time.hour
test_df['weekday'] = prediction_time.weekday()
test_df['month'] = prediction_time.month
def add_join_key(df):
df['join_key'] = df.allah1__27.map(int).map(str)+df.timestamp.map(datetime.isoformat)
df = df.set_index('join_key')
return df
weath_df = wdf.loc[prediction_time]
test_df = add_join_key(test_df)
weath_df = add_join_key(weath_df.reset_index())
And I get this Error:
AttributeError: module 'datetime' has no attribute 'isoformat'
Also I tried:
def add_join_key(df):
df['join_key'] = df.allah1__27.map(int).map(str)+df.timestamp.map(datet.isoformat)
df = df.set_index('join_key')
return df
weath_df = wdf.loc[prediction_time]
test_df = add_join_key(test_df)
weath_df = add_join_key(weath_df.reset_index())
And I get this Error:
AttributeError: DataFrame' object has no attribute 'allah1__27'
Did I miss something?

For the first error: the method isoformat is from datetime that's a method of datetime.
You should:
import datetime
datetime.datetime.isoformat
Or:
from datetime import datetime as datet
datet.isoformat
As for the second error:
df is a dictionary, i think you should call it:
df['join_key'] = df['allah1__27'].map(int).....

How to add tzinfo to date?

I have the following vars:
time_created = datetime.utcnow() and time_created_day = datetime.utcnow().date().
I cannot save time_created_day to the db because of AttributeError: 'datetime.date' object has no attribute 'tzinfo'
How to fix this (add tzinfo)?

Ok, here is one way that I did this.
If you need to add tzinfo, you may use the below.
from datetime import datetime
import pytz
time_created_day = datetime.datetime.utcnow().date()
time_created_day_with_tz_info = datetime(time_created_day.year,
time_created_day.month, time_created_day.day, tzinfo=pytz.timezone('UTC'))
> print time_created_day_with_tz_info
> datetime.datetime(2018, 5, 9, 0, 0, tzinfo=<UTC>)

Date input format? [duplicate]

This question already has answers here:
AttributeError: 'datetime' module has no attribute 'strptime'
(5 answers)
Closed 5 years ago.
I have code like this:
import time
import datetime
def dates():
date1 = str(input('Date start: '))
try:
dt_start = datetime.strptime(date1, '%d, %m, %Y')
except ValueError:
print ("Incorrect format")
date2 = str(input('Date end: '))
try:
dt_end = datetime.strptime(date2, '%d, %m, %Y')
except ValueError:
print ("Incorrect format")
if date1 > date2:
print("Error!")
dates()
And I want to define date input format like d.m.Y.
For example, when I input "17.12.1995". I got error:
'module' object has no attribute 'strptime'.
How to define user input format?

datetime is a module, there is a class with the same name (datetime) within it and that class has a class method strptime(). You need to either call it like:
dt_start = datetime.datetime.strptime(date1, '%d, %m, %Y')
Or to change your import statement:
from datetime import datetime
so that it imports only the datetime class to your current namespace.

Why am I getting the error: 'method_descriptor' object has no attribute 'now'?

If I run the method
from datetime import datetime
from timedelta import time
def action_retbook(self, cr, uid, ids, context=None):
dt = datetime.date.now()
todaydate = datetime.strptime(dt, "%y/%m/%d")
x=6
cr.execute("""update rmkbook_issue set dt_of_return ='%s' where id= %s """ %(todaydate, x))
return
I get the error 'method_descriptor' object has no attribute 'now'. Why?

You can run the method now() like this:
dt = datetime.now()
You can check this question as well

I believe
from datetime import datetime
datetime.now()
Works.. in python 3.9.7

python debug straightforward datetime object

I cannot understand why this is failing, can someone please explain:
import datetime
def test(timestamp):
xt = datetime(2013, 4,4)
dt = datetime.strptime(timestamp, '%d/%m/%Y %H:%M:%S')
print (xt,dt)
test('04/04/2013 08:37:20')
The error is:
Traceback (most recent call last):
File "", line 12, in
File "", line 5, in test
TypeError: 'module' object is not callable
It seems to work ok with from datetime import datetime instead. I can't understand what the difference is.
Thanks.

Because in the datetime module, there is a datetime() function, but you didn't call it ( you instead tried to call the module, that's why you got a TypeError: 'module' object is not callable).
import datetime
def test(timestamp):
xt = datetime(2013, 4,4) # Problem is this line.
dt = datetime.strptime(timestamp, '%d/%m/%Y %H:%M:%S')
print (xt,dt)
test('04/04/2013 08:37:20')
To fix the line, change it to:
xt = datetime.datetime(2013,4,4)
The reason from datetime import datetime worked was because you imported the specific function, and so you wouldn't need to do datetime.datetime().

datetime is both a module AND a class in that module. In your example you need datetime.datetime.

The
xt = datetime(2013, 4,4)
should be
xt = datetime.datetime(2013, 4,4)
Here, datetime is the name of the module. The full name of the class is datetime.datetime.

datetime is the datetime module, datetime.datetime is the datetime type:
import datetime
def test(timestamp):
xt = datetime.datetime(2013, 4,4)
dt = datetime.datetime.strptime(timestamp, '%d/%m/%Y %H:%M:%S')
print (xt,dt)

Here datetime can refer to the module or the class within the module so you have to disambiguate
import datetime
def test(timestamp):
xt = datetime.datetime(2013, 4,4)
dt = datetime.datetime.strptime(timestamp, '%d/%m/%Y %H:%M:%S')
print (xt,dt)
test('04/04/2013 08:37:20')
gives the following output:
(datetime.datetime(2013, 4, 4, 0, 0), datetime.datetime(2013, 4, 4, 8, 37, 20))
