use-implicit-booleaness-not-len / C1802#
Do not use len(SEQUENCE) without comparison to determine if a sequence is empty
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.
fruits = ["orange", "apple"] if len(fruits): # [use-implicit-booleaness-not-len] print(fruits)
fruits = ["orange", "apple"] if fruits: print(fruits)
