enotype

A cross-language type library

from enotype import color

color('#fff') # returns "#fff"
color('#xyz') # raises ValueError("A color is required, for instance '#B6D918', '#fff' or '#01b'.")

from enotype.es import color # with localized error messages

color('#xyz') # raises ValueError("Se requiere un color, por ejemplo '#B6D918', '#fff' o '#01b'.")

Installation

pip install enotype
