Is there a library for Python that will allow me to parse c++ code?
For example, let's say I want to parse some c++ code and find the names of all classes and their member functions/variables.
I can think of a few ways to hack it together using regular expressions, but if there is an existing library it would be more helpful.

In general, already-written C code will require no modifications to be used by Python. The only work we need to do to integrate C code in Python is on Python's side. The steps for interfacing Python with C using Ctypes.
We use the getsource() method of inspect module to get the source code of the function. Returns the text of the source code for an object. The argument may be a module, class, method, function, traceback, frame, or code object. The source code is returned as a single string.
isclass(): The isclass() method returns True if that object is a class or false otherwise. When it is combined with the getmembers() functions it shows the class and its type. It is used to inspect live classes.
There a number of ways to do this. The rawest, simplest way is to use the Python C API and write a wrapper for your C library which can be called from Python. This ties your module to CPython. The second way is to use ctypes which is an FFI for Python that allows you to load and call functions in C libraries directly.
In the past I've used for such purposes gccxml (a C++ parser that emits easily-parseable XML) -- I hacked up my own Python interfaces to it, but now there's a pygccxml which should package that up nicely for you.
