The 'guts' of Python the language include the object model, namespaces
(including modules), and the statement and infix-expression syntax.
(C/C++) and extending it.
Now you are asking about CPython, the leading computer implementation.
But, extending python still seems like a black art to me.

extending it besides the standard sparse ones (http://www.python.org/
doc/2.5.2/ext/intro.html) that may give me more insight? Is there a
class available?
If you want to connect CPython to Python-oblivious code written in C,
Swig (with C code) and Ctypes (with Python code) are the main choices.
If you want to write new Python-aware (and specific) code, you can use
the CPython C-API functions. Extensions in C are written as importable
modules. The interface for such is not difficult; existing examples
should be a good guide.

The 'guts' of an implementation follow from the 'guts' of the language.
There must be a syntax parser and compiler to internal form,
evaluation loop, and implemenations of built-in constants, functions,
classes, and modules. CPython's source tree begins as
http://svn.python.org/view/
You might actually want to start at
http://svn.python.org/view/python/trunk/
Note: if you click a filename, such as 'setup.py', you get the entire
revision history with checkin messages.
If you click the displayed revision number, such as '67978', you get the
latest checkin message and the current version of the file.
How would one go about following an interest in contributing to the
development of python.
Read
http://python.org/dev/
and start following the pydev list, mirrored to gmane.comp.python.devel
at news.gmane.org.
