Fractions in Python | Today I Learned

Today I became aware of the existence of the builtin Python module fractions. The fractions module handles rational number arithmetic.

Here’s a simple example using the Fraction class to covert a decimal into a Fraction with the numerator and denominator reduced to the lowest terms.

>>> from fractions import Fraction
>>> Fraction(0.625)
Fraction(5, 8)

My idea bulb lit up as soon as I discovered the module. As a woodworker, I hate dealing with with decimals. A lot of us have fraction conversion charts in our shops. How nice would it be to skip referencing the chart and get a direct answer for the decimal to fraction conversion?

(I thought about writing an Alexa skill to do this, but she already has that covered.)
