Yes. And it would be a pretty good match, too. There's even been a
commercial game that uses Python for internal scripting, its name
escapes me, though.

Python's documentation has (now) good documentation about it's C API.
Python's API is _C_, though, not C++. There are several C++ wrappers for
it than can simplify the integration a lot. My personal favourite is
Boost::Python. http://www.boost.org/ As a C++ developer, you might be
interested in the other free libraries from Boost, too. What these
people accomplish is really amazing!
