How to handle different return values from a function

I want to make a function in Python that can return different things. How do I handle this correctly? I have something like this:

def function():
    #do something, when everything went allright do:
    return (int, int, int, int)
    # if something went wrong
    return False

x, y, z, a = function()

How do I make this work when the function returns False?

In general, try to avoid this as it makes your functions cumbersome to work with. Raise an exception in case something went wrong, maybe a custom exception that has a "error_message" attribute if you need that, or something.

But you can use a function like yours with

result = function()

if result:
    x, y, z, a = result
else:
    panic()
