addfips 0.1.0

Installing

Add FIPS is a Python package.

pip install addfips

Works in Python 2.7, 3, and pypy.

Features

• Use full names or postal abbrevations for states

• Works with all states, territories, and the District of Columbia

• Fuzzy matching allows for missing diacretic marks and different name formats (‘Nye County’ or ‘Nye’)

(Note that Baltimore city and Baltimore County need to be properly named. Behavior for just passing “Baltimore” is undefined.)
