AttributeError while using timedelta: type object 'datetime.datetime' has no attribute 'datetime'

Question

I have the following code in which am trying to read the time string and reduce the time by 8 hours and print in a human readable format but am running into below error. Can anyone provide guidance on how to fix this?

import time
from datetime import datetime
time_string = '2018-07-16T23:50:55+0000'

#Reduct 8 hours and print in human readable format
struct_time = time.strptime(time_string, "%Y-%m-%dT%H:%M:%S+0000")
t = datetime.datetime(*struct_time[:6])
delta = datetime.timedelta(hours=8)
print(t+delta)

Error:

    t = datetime.datetime(*struct_time[:6])
AttributeError: type object 'datetime.datetime' has no attribute 'datetime'

You either need to: from datetime import datetime then use datetime(*...); or import datetime then use datetime.datetime(*...). The module named datetime contains (amongst other things) a class named datetime, so you have to be aware of which of those names is currently in scope. You're currently trying to access datetime.datetime.datetime which doesn't exist, hence the error. — jonrsharpe

@jonrsharpe - I already have from datetime import datetime in my code,why is it still complaining? — Ritz

Read the error. It's complaining because, despite explicitly importing the class into the current scope as datetime, you're trying to instantiate it as if you'd imported the whole module as datetime. — jonrsharpe

You are importing datetime from datetime. Later in the code you using datetime.datetime, so that's giving you error.

You shoud just call t = datetime(*struct_time[:6])

or

just do import datetime and call it t = datetime.datetime(*struct_time[:6])

The correct program should look like:

import time
import datetime
time_string = '2018-07-16T23:50:55+0000'

#Reduct 8 hours and print in human readable format
struct_time = time.strptime(time_string, "%Y-%m-%dT%H:%M:%S+0000")
t = datetime.datetime(*struct_time[:6])
delta = datetime.timedelta(hours=8)
print(t+delta)

Then it throws an error AttributeError: type object 'datetime.datetime' has no attribute 'timedelta' at line delta = datetime.timedelta(hours=8)

@kemosabee Just write import datetime, not from datetime import datetime and leave the code as it was. I updated my answer

Ritz Over a year ago
