Can't enter exception after try

Question

I am trying to enter the exception part after the try statement. Here is my code

user_date = user.datetime
    try:
        user_date == None
        print(user_date)
    except Exception as e:
        raise Unauthorized(f"Not a date")

the print statement returns 2022-08-22 18:12:53.409212 so that is working correctly. But that means user_date does not equal none. Shouldn't this enter the exception?

Expected output is that it enters the exception since user_date = user.datetime is not None

I would use an if statement except I need to raise an exception without exiting the function.

Thanks in advance.
