title: Simplest way to detect keypresses in Python
body: <p>Currently working on a robotics project in which I need my raspberry pi to detect keypresses (think of game style - instantaneous and always running).  I've looked at using pygame or getch but I'm not really sure which one to use or if I should use either at all.
  I am sure you can tell that I'm pretty new to python, so I would prefer a simple method of doing this.
  I need this to be able to run 100% in a console, as I will not be running this app in X-Window.
  Thanks.</p>
