OK, If it's a program, that is, it compiles into an
executable that you can run then you can run it from
within Python using the subprocess module.

Do you know how you interact with it?
Can you give it start up arguments?
Does it read from stdin?
Does it write to stdout?
Does it read a data file?
Does it write a file out?

You will need to know that to be able to use the
program from inside Python.

I mean running the C++ program and exchanging data
with it. That's what subprocess allows you to do.

If it were a library then you would have to call
the individual C++ functions directly using
something like ctypes, which is usually more
complex.
