PY3.C1802
Use implicit booleaness not len
Used when we detect 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.
Noncompliant Code:
Copy
fruits = ["orange", "apple"]
if len(fruits):
print(fruits)
Compliant Code:
Copy
fruits = ["orange", "apple"]
if fruits:
print(fruits)
