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.

Documentation

Documentation is available at http://wr.readthedocs.org/

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.
