wr is a simple, lightweight module that provides random choice based on weight
Project description
wr is a weighted random implementation in Python.
wr.choice can be fed both mappings (such as dictionaries) and sequences of pairs containing what to return and a integer representing their respective weight. It returns a the key of in case of mappings based on the weights defined in the key’s corresponding value.
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.
