basic python help

[kbjradmin]

i am a student taking a python course, and for one of my assignments i have come up with this:

##  assignmentOne.py
##  requests input from the user and then prints out the result for a math equation.

def main():
    print "This program requests two inputs from the user, adds the values,"
    print "and prints the result."
    print
    x = float(input("Please enter the first value: "))
    y = float(input("Please enter the second value: "))
    print
    print "The value of", x, "+", y, "is", x+y
    print
    if input("Type 'restart' to start over or 'done' to quit: ") == "restart":
        main()
    else:
        end()

def end():
    print "Good Bye!"

main()

i can't get the end part to work right, though.
the whole rest of the program works, but when i tell the program to restart, it doesn't.

please help
Edit:
nevermind, i figured out the problem.
at the end i needed a raw_input, not a regular input.

Please change your line
input("Type 'restart' to start over or 'done' to quit: ")
to :
raw_input("Type 'restart' to start over or 'done' to quit: ")
