[New-bugs-announce] [issue19763] Make it easier to backport statistics to 2.7

[Christian Heimes]

New submission from Christian Heimes:

A while ago I created a backport of statistics to Python 2.6 to 3.3. [1] It worked pretty and required just a few modifications to the code. I'd like to add most modifications to 3.4 to simplify backporting.

The modifications are:

* from __future__ import division
* replace super() with super(MySuperClass, self)
* changes to doc tests because Python 2 has slightly different represenstations (<type 'float'> / <class'float'>, longer float repr)
* "import collections" -> "from collections import Counter" so I can simply add a Counter class for 2.6
* "import math" -> "from math import isfinite" so it's easier to add a isfinite() function for 2.x

The patch does neither remove "raise ... from None" nor does it add a 2.x isfinite or range = xrange. The backport still needs some patches but I can keep the amount of changes rather small.
