if-tuple (F634)

Derived from the Pyflakes linter.

What it does

Checks for if statements that use non-empty tuples as test conditions.

Non-empty tuples are always True, so an if statement with a non-empty tuple as its test condition will always pass. This is likely a mistake.

if (False,):
    print("This will always run")

Use instead:

if False:
    print("This will never run")
