After you follow the other suggestions of read about 'module' and 
'package'.... If you want a module or package available to *all* 
programs (that run with a particular version/installation of Python), 
you can put your module or packages in the 'site-packages' directory. 
On Windows, this is a subdirectory of pythonxy/lib/

 >>> import sys; sys.path
['C:\\Programs\\Python30\\Lib\\idlelib', 
'C:\\WINDOWS\\system32\\python30.zip', 'C:\\Programs\\Python30\\DLLs', 
'C:\\Programs\\Python30\\lib', 'C:\\Programs\\Python30\\lib\\plat-win', 
'C:\\Programs\\Python30', 'C:\\Programs\\Python30\\lib\\site-packages']
