Suggestion: Use Python3 Syntax

[nstr10]

At a glance, this would run fine in Python3 if the print statements used parentheses. Please consider updating your syntax to work with modern Python versions.

Thanks!

P.S. If you'd prefer this suggestion in the form of a pull request, I'll gladly oblige.

i added the parentheses. pull request will work too of course (in case I didn't do it right)
