it looks good. I wanted to point out a couple builtins that help you here. One, you don't need to close the files when using the 'with' statement (+Andre Müller
picked that out too). Two, using the readlines() function handles all the newline stripping, Three by putting it inside the 'zip' function your script will handle unequal inputs in a predictable way. The main story is that Python has SO many built-ins that a lot of the complex stuff melts away into the imports, you just have to know them. Happy coding, and keep it up.
