possibly-unused-variable / W0641

Message emitted:

Possibly unused variable %r

Description:

Used when a variable is defined but might not be used. The possibility comes from the fact that locals() might be used, which could consume or not the said variable

Problematic code:

def choose_fruits(fruits):
    print(fruits)
    color = "red"  # [possibly-unused-variable]
    return locals()

Correct code:

def choose_fruits(fruits):
    current_locals = locals()
    print(fruits)
    color = "red"
    print(color)
    return current_locals
