Yes, it is, but let me first clarify something: "Smaller" and "more
efficient" are two quite different concepts. Efficiency doesn't matter
to your code here, so what you're looking for is smaller, clearer
code. Which is a good thing to be doing :)
At top level, the 'global' declaration doesn't do anything. You may as
well not bother with it.
If you change your recursive main() function into a while loop, you'll
be able to combine all your common code very easily. I won't do the
whole job for you, but consider this structure:
repeat=1
while repeat==1:
# get inputs
# calculate and produce output
repeat=int(raw_input("Do you want to do more? "))
And if you need your error state to have a different prompt, you can
use 'continue' to skip the bottom of the loop.
Hope that helps!
