expr-or-true (SIM222)#

Derived from the flake8-simplify linter.

Fix is always available.

What it does#

Checks for or expressions that contain truthy values.

Why is this bad?#

If the expression is used as a condition, it can be replaced in-full with True.

In other cases, the expression can be short-circuited to the first truthy value.

By using True (or the first truthy value), the code is more concise and easier to understand, since it no longer contains redundant conditions.


if x or [1] or y:

a = x or [1] or y

Use instead:

if True:

a = x or [1]
