assignment-from-no-return / E1111

Message emitted:

Assigning result of a function call, where the function has no return

Description:

Used when an assignment is done on a function call but the inferred function doesn't return anything.

Problematic code:

def add(x, y):
    print(x + y)


value = add(10, 10)  # [assignment-from-no-return]

Correct code:

def add(x, y):
    return x + y


value = add(10, 10)
