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. ChrisA
