wr (Weighted Random)
wr is a weighted random implementation in Python.
wr.choice can be fed with a mapping (such as dictionaries) containing a returnable (what to return) and a integer representing their respective weight.
The key can be anything hashable but the weight must be a integer.
Optionally you may feed wr.choice with a sequence of pairs.

Example
>>> import wr
>>> data = {'cat': 60, 'dog': 30, 'bird': 10}
>>> animal = wr.choice(data)
>>> print animal
cat # well, the cat had a good 60% shot at it.
Installation
Install wr with pip install wr or just download wr.py and place it in your project directory.
