I try go get datetime object class from sqlalchemy query like this:
curr_date = engine.execute("SELECT getdate() ").fetchall()
dt = [d.strptime('%d/%m/%y %H:%M:%S') for d in curr_date]
and get this error:
Traceback (most recent call last):
...
dt = [d.strptime('%d/%m/%y %H:%M:%S') for d in curr_date]
AttributeError: Could not locate column in row for column 'strptime'
Please, advise, how to fix it?
It seems like I solved:
curr_date = engine.execute("SELECT getdate() ").fetchone()
print(curr_date[0])

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).....
Can someone help with me this?
I am using Flatlib to compute planet positions, but the code for entering the date and time for computation is fixed, so you have to update it each time.
Is there a way to using datetime.now() [or another way] to complete the fields in the Datetime() automatically? I can't get the code in the date = Datetime() to accept any form of datetime code.
I looking to get Datetime() to accept month/day/year and hour:minute:second format eg (08/24/2018, 21:17:00)
With the below code i get the following error:
C:\Users\famil>C:\Users\famil\Desktop\flatlib_working_degree.py
('{0.month}/{0.day}/{0.year}', '21:15:41')
Traceback (most recent call last):

from flatlib.datetime import Datetime

# set date and time to now
now = datetime.datetime.now()

print(x)
date = Datetime(x)
pos = GeoPos('53n15', '2e31')
chart = Chart(date, pos, hsys=const.HOUSES_PLACIDUS, IDs=const.LIST_OBJECTS)
# calculate body and degree value
asc = chart.get(const.ASC)
print(asc, asc.lon)
sun = chart.get(const.SUN)
print(sun, sun.lon, sun.movement())
moon = chart.get(const.MOON)
Flatlib's Datetime demands 2 separate inputs for date and time, as you can check here: Github: flatlib/datetime.py
.
def __init__(self, date, time=0, utcoffset=0, calendar=GREGORIAN):
But your code has only datetime 1 argument, separated by comma. That's incorrect:
now = datetime.datetime.now()
date = Datetime(now.strftime("%Y/%m/%d, %H:%M"))
You should write it like this:
now = datetime.datetime.now()
date = Datetime(now.strftime("%Y/%m/%d"), now.strftime('%H:%M'))
I have a python script
import urllib2
from bs4 import BeautifulSoup
import requests
import csv
from datetime import datetime
from datetime import date
from datetime import timedelta
def generateDateList(date,month,year):
today = date(year, month, date)
arrDates = []
for i in range(0,5):
arrDates.append(datetime.strftime(today + timedelta(days=i),"%d-%m-%y"))
return arrDates
print generateDateList(4,12,2017)
But i get this error-
Traceback (most recent call last):
File "test.py", line 17, in <module>
print generateDateList(4,12,2017)
File "test.py", line 11, in generateDateList
today = date(year, month, date)
TypeError: 'int' object is not callable
Why is it failing? I substituted the function with values and it worked. Should i convert the function inputs to integer again?
This line - def generateDateList(date,month,year):
The name of the first argument date shadows the name date imported at the top. You need to rename the argument to something like day inside your function.
As written, date is actually an integer you pass to the function, and calling it results in an error you are seeing.
Two options.
Option No.1 (import datetime):
import datetime
def generateDateList(date, month, year):
today = datetime.date(year, month, date)
arrDates = []
for i in range(0,5):
arrDates.append(datetime.datetime.strftime(today + datetime.timedelta(days=i),"%d-%m-%y"))
return arrDates
print generateDateList(4, 12, 2017)
Option No.2 (rename date parameter to day):
from datetime import datetime
from datetime import date
from datetime import timedelta
def generateDateList(day,month,year):
today = date(year, month, day)
arrDates = []
for i in range(0,5):
arrDates.append(datetime.strftime(today + timedelta(days=i),"%d-%m-%y"))
return arrDates
print generateDateList(4,12,2017)
The problem is the fact you have a parameter with the same name of the date() function.
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
I have the following lines of code in project A
#filename : mod_dates
#Handles date calculations etc
import datetime
class datecalcs:
def __init__(self):
self.__menuChoice = 0
self.__datemonth = "not set"
self.__effectivedate = ""
self.__year = 0
self.__month = 0
return None
#
def interestcouponpaydates(self,effectivedate,couponday):
self.__effectivedate = effectivedate
year, month, day = map(int,self.__effectivedate.split('-'))
print(year)
print(month)
return self.__effectivedate
When I call them from another file with
import mod_dates
import datetime
import modcalinputs
datesclass = mod_dates.datecalcs()
calcInputs = modcalinputs.calcinputs()
#Get the coupon date
interestdateeffective = calcInputs.interestdateffective()
interestdatecoupon = calcInputs.interestdatecoupon()
x = datesclass.interestcouponpaydates(interestdateeffective,interestdatecoupon)
print(x)
However this returns an error on the x = datesclass... line of
year, month, day = map(int,self.__effectivedate.split('-'))
raises:
> AttributeError: 'datetime.date' object has no attribute 'split'
When I run from a similar project to the same line with the same syntax it works fine. Any ideas on what I am doing wrong?
Looks like something is assigning a datetime.date object to __effectivedate. You can't call split() on that:
>>> import date
>>> d = d = datetime.date(2012,3,12)
>>> d.split('-')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'datetime.date' object has no attribute 'split'
You can convert it to a string and split:
>>>str(d).split('-')
['2012', '03', '12']
