No beginner is expected to read the source code itself to figure
things out.  Go to the online documentation at http://docs.python.org
and browse through it.  Make sure you read the tutorial, but if
you have questions about specific modules, go to the Global Module
Index.

For example, read the first sentence of each of these two learn the
purpose of the modules you mentioned:

http://docs.python.org/lib/module-sys.html
http://docs.python.org/lib/module-os.html
http://docs.python.org/lib/module-random.html
