Proper way to quit a function in Python

Question

Assume I have the following ;

def test():
    while 1:
        a = b
        time.sleep(60)
        c = b
        if(c==a):
            do something
            then quit the function

What is the proper way to quit from a function having this structure ?

Answer 1

You could just use a return statement.

That would be the most direct way, by just placing the return where you want to quit ("then quit the function").

  if(c==a):
     do something
     return 

You could also use this to return any results you have to the calling code.

Eg., return some_results

Answer 2

Use the return statement: eg

def test():
    while 1:
        a = b
        time.sleep(60)
        c = b
        if c == a:
            print a
            return

break would also work, by leaving the while loop.

Answer 3

Just use the return statement to exit the function call.

def blah():
    return  # Returns None if nothing passed back with it
def blah():
    return some_value, some_value2 # Return some values with it if you want.
