Brightway2 parameters

Coverage Status Build status Documentation Status

Library for storing, validating, and calculating with parameters. Designed to work with the Brightway2 life cycle assessment framework, but is generic enough to work in other use cases.

In [1]: from bw2parameters import ParameterSet

In [2]: parameters = {
   ...:        'Deep_Thought': {'amount': 42},
   ...:        'East_River_Creature': {'formula': '2 * Deep_Thought + 16'},
   ...:        'Elders_of_Krikkit': {'formula': 'sqrt(East_River_Creature)'},
   ...: }

In [3]: ParameterSet(parameters).evaluate()
Out[3]: {'Deep_Thought': 42, 'East_River_Creature': 100, 'Elders_of_Krikkit': 10.0}

Compatible with Python 2.7, 3.3, and 3.4. 100% test coverage. Source code on bitbucket, documentation on Read the Docs.
