A couple of points:

1. Trying not to use the names of built-in classes or functions for
your variable names, for example "list".

2. In Python 2 int/int returns an int, but in Python 3 int/int returns
a float. In both cases int//int returns an int (at least for recent
versions of Python 2), so it's a good idea to always use // when you
want to do integer division.
