No you don't. def f(x): return x+1 def g(x): return x-1 If I choose to refactor f() and change "x" to "y", why do I care about the internal variable inside g()? Oh wait, I get it... you want to do a global search-and-replace over the entire file. *face-palm* If your functions are less than one-screen full, why do you need a global replacement? Global replacement risks changing words in docstrings, comments etc that it shouldn't. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
