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

Thankyou.
It's clear, this definitely helps me with the first question. But still
doesn't explain almost anything about the example i've posted in the last
post, right?

Ok, so i think the key is of my problem is that when doing X = 0 i'm
creating a new object, that only exist in the local namespace. BUT, when

what text-editor do you use for python?
I've always used kate/nano on Linux and Notepad++/PSPad on Win. Today i've

Do you think it's a good editor? Do you know other names?

so, going back to your example:
