useless-comparison (B015)#

Derived from the flake8-bugbear linter.

What it does#

Checks for useless comparisons.

Why is this bad?#

Useless comparisons have no effect on the program, and are often included by mistake. If the comparison is intended to enforce an invariant, prepend the comparison with an assert. Otherwise, remove it entirely.


foo == bar

Use instead:

assert foo == bar, "`foo` and `bar` should be equal."
