The __builtin__ module is built-in, there is no Python source for it. It is encoded in C and included as part of the Python interpreter executable.

You can not. it is built into the interpreter.

 >>> # os is from '/usr/lib/python2.7/os.pyc' >>> import os >>> os <module 'os' from '/usr/lib/python2.7/os.pyc'> >>> # PyQt4 is from '/usr/lib/python2.7/site-packages/PyQt4/__init__.pyc' >>> import PyQt4 >>> PyQt4 <module 'PyQt4' from '/usr/lib/python2.7/site-packages/PyQt4/__init__.pyc'> >>> # __builtin__ is built-in >>> import __builtin__ >>> __builtin__ <module '__builtin__' (built-in)>

In the program, you can use the __file__ attribute, but the built-in modules do not have it.

 >>> os.__file__ '/usr/lib/python2.7/os.pyc' >>> PyQt4.__file__ '/usr/lib/python2.7/site-packages/PyQt4/__init__.pyc' >>> __builtin__.__file__ Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'module' object has no attribute '__file__'
