[Tutor] How to print on screen and to a file, meanwhile?

[Kent Johnson]

The logging module is good for this. You can set it up to log to the screen and a file. You have to 
do some setup and change your print statements to call a logger.

See this section of the docs and the one following for examples.
http://www.python.org/dev/doc/devel/lib/minimal-example.html

It's easier than it looks, you just have to take a little time to figure out how to set it up the 
way you like it.
