That's not what I said, though! What you did in JS was the equivalent of this: >>> type(True) == type(1) False which isn't the same as an isinstance check. Instead, try *exactly what I said*. You'll find that false is equal to zero and true is equal to one, just like it is in Python. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
