string-dot-format-extra-positional-arguments (F523)

Derived from the Pyflakes linter.

Fix is sometimes available.

What it does

Checks for str.format calls with unused positional arguments.

Why is this bad?

Unused positional arguments are redundant, and often indicative of a mistake. They should be removed.

Example

"Hello, {0}".format("world", "!")

Use instead:

"Hello, {0}".format("world")
