Unless it uses one of the few things that are system dependent. But 
these are marked in the docs (example: "Abailability: Unix") and are 
mostly in the os module. An example is os.fork. There are also some 
system-specific things in the socket module, although it embodies much 
effort to make things as cross-platform as possible.
