native-literals (UP018)

Derived from the pyupgrade linter.

Fix is always available.

What it does

Checks for unnecessary calls to str, bytes, int, float, and bool.

Why is this bad?

The mentioned constructors can be replaced with their respective literal forms, which are more readable and idiomatic.

Example

str("foo")

Use instead:

"foo"

The fix is marked as unsafe if it might remove comments.
