Subject: Portable Python script across Python version
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8d4d731fb7848841adb91cfb3bed162a14c679e7;p=clang

Portable Python script across Python version

In Python2, division between integer yields an integer, while it yields a float in Python3.
Use a combination of from __future__ import division and // operator to get a portable behavior.
