C1801 (len-as-condition)
Problematic code:
array = []
if len(array):
pass
Correct code:
array = []
if len(array) > 0:
pass
Rationale:
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.
