Fix undefined names in Python 3

reload() was moved in Python 3 and file(), long, __raw_input(), and xrange() were removed and print()__ became a function. This PR proposes fixes that provide equivalent functionality in both Python 2 and Python 3.

Before this PR: flake8 testing of https://github.com/joxeankoret/pigaios on Python 3.7.1
