I found effbot's guide to the standard library helpful -- and although 
it's nor current, you'll still get a good idea of where things are at 
and how to use them.  See http://effbot.org/zone/librarybook-index.htm

Also, experiment with help() from the python prompt.  Once in the help 
system, type in 'modules' to see a list of installed available modules 
to explore, or a module name for more info on that module.

HTH,
