[Tutor] Defining functions

[Jacob S.]

Try this.

import sys

def my_raw_input(prompt):
    sys.stdout.write(prompt)        ## Since they're thinking of bonking off 
print as well.
    a = sys.stdin.readline()
    if a.startswith(prompt):
        return a[:len(prompt)]
    return a

It leaves the '\n' on the end... so it sucks.

I know there is a better way... Someone else-help?
