sounds like they (or you) are confusing "arguments" with "free
variables", though. here's an example of the latter:
def outer():
var = [value]
def inner():
var[0] = new value
inner()
here's an example of the former:
def func(var):
var[0] = new value
return something else
myvar = [value]
res = func(myvar)
the second example feels rather contrived; if you need to return
multiple values, just return them.
