tab compleation input

[dakman at gmail.com]

On a gui on this would be a little bit easier but it's a completley
diffrent realm when doing it in the console. It makes it a little more
difficult when using stdin.readline() because you can only read line by
line. Here is my implmentation.

import sys

validanswers = [ 'yes', 'no', 'maybe', 'tuesday', 'never' ]
while True:
    sys.stdout.write("Answer the Question: ")
    answer = sys.stdin.readline().rstrip()
    for valid in validanswers:
        if valid.startswith(answer.strip("\t")):
            answer = valid
    else:
        print "Invalid Answer: Please enter a valid answer"
        continue
    break
print "You have answered, ", answer

I'm at school and wasn't able to test it, but it looks like it should
work.
