It looks like you have named a string 'input'; this hides the built-in
'input' function and causes the error you are seeing. Restart IDLE and
input() should work correctly.
A safer way to accept an integer is to use raw_input() and convert the
result yourself:
try:
speed = int(raw_input(prompt))
except ValueError:
print 'You did not enter an integer'
