superfluous-else-continue (RET507)

Added in v0.0.154 · Related issues · View source

Derived from the flake8-return linter.

Fix is sometimes available.

What it does

Checks for else statements with a continue statement in the preceding if block.

Why is this bad?

The else statement is not needed, as the continue statement will always continue onto the next iteration of a loop. Removing the else will reduce nesting and make the code more readable.

Example

def foo(bar, baz):
    for i in bar:
        if i < baz:
            continue
        else:
            x = 0

Use instead:

def foo(bar, baz):
    for i in bar:
        if i < baz:
            continue
        x = 0
