How to Fix datetime Import Error in Python Quickly

Here's a quick resolution for import datetime Python error. The reason is your .py python script name and datetime are the same. I'll show you how this error happens and its resolution.


 datetime import error


Here's the Resolution for ImportError


I've created a script called 'datetime.py.' to check whether the minute value is 'odd' or not. During the import of my python script, I got the import error cannot import name datetime.

My Script: datetime.py

My script's intention is to find whether the minute value is odd or not.

Python Logic


from datetime import datetime
odds = [ 1, 3, 5, 7, 9, 11, 13, 15, 17, 19,
21, 23, 25, 27, 29, 31, 33, 35, 37, 39,
41, 43, 45, 47, 49, 51, 53, 55, 57, 59 ]
right_this_minute = datetime.today().minute
if right_this_minute in odds:
print("This minute seems a little odd.")
else:
print("Not an odd minute.")


ImportError


I have imported my datetime.py from Linux. It gives an error "ImportError: cannot import name 'datetime' from partially initialized module'.



ImportError


The reason for the error is the .py module name and Python package name both are the same.


Resolution

I've renamed the .py module and imported it to Python3. Then, the import is successful.
