This is telling you there's no such thing as "date".

Since there's no such thing as "date", you can't use it.

Nope, OS doesn't have a "date" either.

Getting closer...

Since you're working with time, the best place to start is with (from
the command line), `pydoc time`, which would tell you:

                    
 ctime(...)
   ctime(seconds) -> string

   Convert a time in seconds since the Epoch to a string in local time.


So, the correct way to do it is:

import time
time.ctime(os.path.getmtime("yahoo.py")

Hey, look, I figured out what you wanted before you even asked! :)
