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 and 3.3+. 100% test coverage. Source code on Github, documentation on Read the Docs.
