Two million Google hits for "nonlocal" seems like plenty.
The explanation of "nonlocal" is pretty straightforward --
If the definition of f() contains an assignment to x, then
x is a local variable in f, unless x is declared nonlocal.

But it's the wrong word. "Purple" also meets all of these requirements.
I'd rather accurately express the concept in the negative (the
true meaning really is in the negative: "don't make a new binding"),
than choose a simple-sounding word that is essentially a lie.
x = 1
def f(x):
print x
def g():
global x
x = 3
print x
The "x" used in g is not global at all -- it belongs to f.
