What is the best way to exit a function (which has no return value) in python before the function ends (e.g. a check fails)?

by

Let’s assume an iteration in which we call a function without a return value. The way I think my program should behave is explained in this pseudocode:

for element in some_list:
    foo(element)

def foo(element):
    do something
    if check is true:
        do more (because check was succesful)
    else:
        return None
    do much much more...

If I implement this in python, it bothers me, that the function returns a None. Is there a better way for “exiting a function, that has no return value, if a check fails in the body of the function”?
