The Scoop on Python Input?

[GulickDO at uReach.com]

Hey gang.  I recently fell in love with Python for Linux and have 
been doing a fair amount of work programming console-based apps.  I 
have about three or four Python reference books and was pretty 
disappointed how poorly the concept of "input" was covered in the 
books!  So maybe someone here can send me in the right direction.

Is there a Python input function that will get just one character 
from the keyboard without waiting for enter to be pressed? (like getch
() in C++?)  I found a module that provides getch(), but it is 
restricted to Window's-based platforms.

Any suggestions would be appreciated.

Thanks.

G.
