How to break a Python while loop from a function within the loop

Question

while True:
    input = raw_input(\"enter input: \")
    result = useInput(input)

def useInput(input):
    if input == \"exit\":
        break   #return 0 / quit /          


        

Answer 1

1. Raise an exception, that you can handle outside the While loop
2. Return a flag to be captured by the caller and handle accordingly. Note, "if logic" directly in the while loop,, would be the most preferred way.
