Decode resistor color codes and encode resistance values

Resistors

A Python library for decoding resistor color codes and encoding resistance values.

• Converts colors to value
• Converts value to colors
• Supports four and five-band resistors
• Zero dependencies

The library strictly follows the following chart:

Using colors not listed in this chart will result in a KeyError or ValueError.

Installation

pip3 install resistors

Usage

from resistors import Resistor

r1 = Resistor("red", "red", "black", "black", "brown")
print(r1.get_resistance())  # {'value': 220.0, 'tolerance': 1.0}
r2 = Resistor.with_resistance(1230, 2, 5)   # create resistor object with value of 1230Ω, tolerance of +-2%, and 5 bands
print(r2.get_colors())  # ['brown', 'red', 'orange', 'brown', 'red']
