While it's true that Python is statically scoped, that has nothing at all to do with the code from the OP's question, which contains only one (global) scope anyway. The real issue is confusion between name binding and object mutation. By reassigning c and d, the OP is evidently trying to mutate the list named x (or to be more precise, the list that is the second element of the list named x). But this doesn't work, because name-binding doesn't mutate objects as it does in languages with variable semantics (C, for example); it merely rebinds the names to different objects. c and d end up bound to values that weren't in the list to begin with, meanwhile the list remains unchanged and e and f are still just bound to None. -- http://mail.python.org/mailman/listinfo/python-list
