In the environment variable "PYTHONPATH" (from Zope 2.7 on, you
can extend it (sometimes) from the configuration file).

There is not special treatmend for (normal) modules.
There are funky stuff for "External Methods" but apparently
we do not speak about them...

The primary source of the python path is the environment variable
PYTHONPATH (on windows, it can be determined by a registry entry).
Zope extends it a bit (to find its infrastructure).
Python extends it a bit (to find its runtime library.
Your application can further extend it a bit.

You can see the effective Python path in "Control_Panel -->
Debug information". Watch out for "sys.path".
