module 'datetime' has no attribute 'strptime'

This error occurs when you try to use the strptime function from the datetime module, but it is not available in the version of Python you are using.

The strptime function is available in Python 2.4 and later, and in Python 3.0 and later. If you are using an earlier version of Python, you will need to update to a newer version to use this function.

If you are already using a version of Python that supports strptime, make sure that you are importing the datetime module correctly. You should use the following syntax:

import datetime

# Then you can use the strptime function like this:
date_string = "2021-05-25"
date_object = datetime.datetime.strptime(date_string, '%Y-%m-%d')

If you are still having trouble, check that you have not accidentally named a file in your working directory "datetime.py", as this can cause naming conflicts and prevent you from importing the datetime module correctly.
