Message emitted:

Do not use len(SEQUENCE) without comparison to determine if a sequence is empty

Description:

Used when Pylint detects that len(sequence) is being used without explicit comparison inside a condition to determine if a sequence is empty. Instead of coercing the length to a boolean, either rely on the fact that empty sequences are false or compare the length against a scalar.
