How to poll for GPIO interrupts in python?

Question

I need to poll for interrupts on a GPIO pin using python 2.7, and I wonder if there are any native functions or libraries to help me do that?
When searching for anything like this I find a lot about Raspberry Pi, but that is not what I need.

Is this doable?

It will be greate if you post what you already tried so we can help.

I did it like this

while 1:
    events = po.poll(30000)
    if not events:
        print ('TIMEOUT!')
    for fd, flag in events:
        # check what's been done with os.lseek and os.read

This code is based on How do I wait for interrupts in different languages? question.

Whole code was done as a simple game for emebeded system on Raspberry PI and is available here
