wr 0.2.1

wr is a simple, lightweight module that provides random choice based on weights.

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.

>>> data = {'cat': 60, 'dog': 30, 'bird': 10}
>>> animal = wr.choice(data)
>>> print animal
cat # well, the cat had a good 60% shot at it.
