Start nano as a subprocess from python, capture input

I'm trying to start a text editor (nano) from inside Python, have the user enter text, and then capture the text once they writeout (Control-O). I haven't worked with the subprocess module before, nor pipes, so I don't know what to try next.So far I have this code:a = subprocess.Popen('nano', stdout=subprocess.PIPE, shell=True)Where a should capture the output. This code, however, doesn't bring up nano, and instead makes the python terminal behave strangely. Up and down keys (history) stop working and the backspace key becomes dysfunctional.Can someone point me in the right...

How do I use Sprite Sheets in Pygame?

Argh!!! I am new to this whole python thing and the only way I know how to make a "animation" is by using individual pictures (as in 1 pic per file). Well, I got a sprite sheet that is perfect for what I need, only problem is that it is a sprite sheet. I don't want to spend the time, cropping each individual sprite out.More information, I am new to python and pygame. Just started learning the language back in August is a class that is moving very slowly...so if you could explain what you are doing so I can do it for future projects I would really appreciate it. I am also us...
