unnecessary-literal-within-list-call (C410)

Derived from the flake8-comprehensions linter.

Fix is always available.

What it does

Checks for list calls that take unnecessary list or tuple literals as arguments.

Why is this bad?

It's unnecessary to use a list or tuple literal within a list() call, since there is a literal syntax for these types.

If a list literal is passed in, then the outer call to list() should be removed. Otherwise, if a tuple literal is passed in, then it should be rewritten as a list literal.

Examples

list([1, 2])
list((1, 2))

Use instead:

[1, 2]
[1, 2]

Fix safety

This rule's fix is marked as unsafe, as it may occasionally drop comments when rewriting the call. In most cases, though, comments will be preserved.
