Useful things to know--stdin, stdout, and stderr

Note: This is an old post in a blog with a lot of posts over a long span of time. The world has changed, technologies have changed, and I've changed. It's likely this is out of date, the code doesn't work, the ideas haven't aged well, or the ideas were terrible to begin with. Let me know if you think this is something that needs updating.

I was reviewing something and learned that Python saves the original sys.stdin, sys.stdout, and sys.stderr as sys.__stdin__, sys.__stdout__, and sys.__stderr__ respectively. That's pretty handy to know. Works in at least Python 2.5 and up--I didn't test earlier versions.
