unnecessary-direct-lambda-call (PLC3002)

Added in v0.0.153 · Related issues · View source

Derived from the Pylint linter.

What it does

Checks for unnecessary direct calls to lambda expressions.

Why is this bad?

Calling a lambda expression directly is unnecessary. The expression can be executed inline instead to improve readability.

Example

area = (lambda r: 3.14 * r**2)(radius)

Use instead:

area = 3.14 * radius**2
