This is largely unrelated to whether you use Python. Rather, you need to
know what operating system (OS) services are available on your chosen
OS, that will allow the capability you're asking for.

Then, once you know what OS service to use for simultaneous sound
channels, you can look for a way to use Python to interface with that.

What OS will you be using? I know that the JACK library
<URL:http://jackaudio.org/> has the capabilities you're asking about,
which would make GNU+Linux a good choice.
