It does indeed appear to work. And thank you for posting your current
code. However...

This should never be done. Do not do this. Your use of raw_input
proves that you're using Python 2, and in Python 2, never ever ever
use input(). There are two solutions:
1) Use raw_input everywhere
2) Use Python 3, and add parentheses to the few print() calls that
don't have them.
Either way, the correct fix also involves accepting *strings* from the
keyboard, and then converting them. The problem with input() is that
it automatically converts what the user types, according to the rules
of source code; you almost never want this. For example, entering 08
will result in an error, but 08.50 is the same as 8.50.
After that, you can start looking at the totals. But I'm not going to
write the code for you; you can start writing code, and when you get
stuck, come and ask for help.
