Actually, those examples are more usually global *constants* (or at least the closest thing that Python has to constants). While we can rebind math.sqrt, as in your example, treating it as a variable, we normally would not do so. We would normally treat such module level objects as constants. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
