Well, I don't know of a tutorial, but programmers suffering from C addiction
<wink> usually want examples more than text.  Python itself is choked with
examples:  the Modules and Objects directories of the Python source
distribution are full of examples of "extending" Python.  Most modules and
builtin types don't have any special privileges -- if they didn't exist, you
could write them and link them into Python yourself.

Note two of the manuals in the standard Python doc set:

    Extending and Embedding
    Python/C API

This first one walks you through some simple examples, and arguably is a
tutorial; the second is more of a reference manual.
