You can manually go and check the PYTHONPATH variable contents to find the directories from where these built in modules are being imported. Running "python -v"from the command line tells you what is being imported and from where. This is useful if you want to know the location of built in modules.
Usually in /lib/site-packages in your Python folder. (At least, on Windows.) You can use sys. path to find out what directories are searched for modules.
Packages support one more special attribute, __path__ . This is initialized to be a list containing the name of the directory holding the package's __init__.py before the code in that file is executed. This variable can be modified; doing so affects future searches for modules and subpackages contained in the package.
How can I easily find the path to a Windows PowerShell module? Use the Get-Module cmdlet and a wildcard character for the name, and select the Path property.
It is worth mentioning that packages have __file__ attribute which points to __init__.py, they also have __path__ which points to the package directory. So you can use hasattr(module_name, '__path__') and module_name.__path__[0] or module_name.__file__.
Example (in REPL):
import socket, SOAPpy # SOAPpy is a package
socket.__file__
# .../python2.5/socket.pyc
socket.__path__
# AttributeError: 'module' object has no attribute '__path__'
SOAPpy.__file__
# .../2.5/site-packages/SOAPpy/__init__.pyc
SOAPpy.__path__
# ['.../2.5/site-packages/SOAPpy']
