Here's a tip: when all else fails, read the manual. In this case:

http://docs.python.org/3.0/library/functions.html#input

"""The function then reads a line from input, converts it to a string
(stripping a trailing newline)"""

If you are desperate for getch() and getche(), see here:

http://docs.python.org/3.0/library/msvcrt.html?highlight=msvcrt#console-i-o

HTH,
John
