Built-ins aren't quite the same as globals, but essentially yes: $ python Python 2.6.6 (r266:84292, Jan 12 2011, 13:35:00) >>> len <built-in function len> >>> len = 5 >>> len 5 >>> del len >>> len <built-in function len> >>> del len Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'len' is not defined >>> len <built-in function len> Cheers, Chris -- http://rebertia.com -- http://mail.python.org/mailman/listinfo/python-list
