Most modules do have corresponding files. The exceptions are the ones
built-in to Python. In fact modules have a __file__ attribute that tells
you where it came from; try typing
factor30.__file__

>>> import factor30
>>> factor30._file_
 
Traceback (most recent call last):
  File "<pyshell#2>", line 1, in -toplevel-
    factor30._file_
AttributeError: 'module' object has no attribute '_file_'
>>> 
 
>>> factor30.__file__
'c:\\math\\factoring\\factor30.py'
>>> 
 
Ok.   Now I understand it.
 
The module is named factor30.
 
The file is named factor30.py
 
I presume that if I created another library in the same directory
in a file named factor31.py
that it would create a module named factor31.   ???
