How Can Functions Help Break Out of Nested Loops Efficiently?

Breaking Out of Nested Loops with Functions

Consider the code snippet presented, which employs nested loops but fails to break out of both due to the invalid usage of break 2. Instead of the nested loop approach, refactoring into a separate function may be a more effective solution.

def get_confirmation():
    while True:
        ok = get_input("Is this ok? (y/n)")
        if ok.lower() == "y": return True
        if ok.lower() == "n": return False

while True:
    # Snip: print out current state
    if get_confirmation(): break
    # Do more processing with menus and stuff

In this example, the get_confirmation() function is defined to handle the user input and "OK" confirmation logic. By utilizing a function, the code flow becomes more manageable, and we can utilize the return statement to exit the function and, subsequently, the outermost loop if the user responds with "OK."
