It might be more beneficial to work the other way around, use Python
for, as someone else said, the scripting of objects within your
world. It's a convenient language for short tasks: rapid development
and good maintainability make it suitable.  Given how easy it is to
embed such languages in C and C++ code, it can make sense to do so.

Python offers portable asynch I/O; see
http://www.nightmare.com/medusa/programming.html for a library built
on top of it.  Python exposes a select() interface and a poll()
interface; poll() of course is less widely supported.

But once again, you can build your application in C, and deal with
portability via libraries such as glib, and add scripting support on
top of it, and get the best of both worlds.
