Re: [Tutor] Functions returning multiple values

I have an update: I can easily undertand why this example doesn't work: def nochange(x): x = 0 y = 1 nochange(y) print y # Prints out 1 X is a local variable, and only gets modified in the function, that doesn't return any value. But it's very difficult for me to understand WHY this works:
