It would be _convenient_ to have such a function for inspection, but it's not a requirement. Here's a function that shows lexical scope in action: ########################## >>> def pair(x, y): ... def f(b): ... if b: return x ... return y ... return f ... >>> p = pair(3, 4) >>> p(True) 3 >>> p(False) 4 ########################## _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
