Is it possible to view the source code of Python's functions like sum, zip and the like? I just want to know about the implementation.
Thanks.

The source of the modules is (fairly obviously) in the Modules directory.

sum and zip aren't modules though. He's asking about the backend C code.
Source for builtins functions (like sum, zip, etc) are in http://hg.python.org/cpython/file/57c157be847f/Python/bltinmodule.c.

You cant see the code for the sum and zip because those are wrapper of c functions. But other module you can check on http://hg.python.org/cpython/file/2.7/Lib

This will give you the location of the Python source code files on disk:
import sys
print(["%s %s" % (k,v) for k,v in sys,modules.items()] if k == "re")
On Windows, it is usually found on C:\python33\lib\. and on Linux it is /usr/python2.7/lib/....
Once there, you can view the .py files as you wish.

I think OP is asking for the C source code of the internal funcions like sum, min, max, reduce and so on
