Fix is sometimes available.

This rule is unstable and in preview. The --preview flag is required for use.

What it does#

Checks for literals that are similar to constants in math module.

Why is this bad?#

Hard-coding mathematical constants like π increases code duplication, reduces readability, and may lead to a lack of precision.


A = 3.141592 * r**2

Use instead:

A = math.pi * r**2
