AttributeError: type object 'datetime.datetime' has no attribute 'datetime'

This error occurs when you try to access the attribute 'datetime' on the class 'datetime.datetime'. This is not a valid attribute because 'datetime' is already the name of the class.

To fix this error, you can simply remove the redundant 'datetime' attribute and use the class name directly. For example:

import datetime

dt = datetime.datetime.now()

In this example, we are accessing the 'now' attribute of the 'datetime' class directly, without using the redundant 'datetime' attribute.
