Actually that's not the case; certain syntactic constructs allow you to specify multiple of something, without packaging them up into a tuple. Function arguments and parameters are like this; otherwise keyword arguments would have to be some kind of magic syntax in tuples, instead of being a feature of function calls. But there are plenty of situations where what you're describing _is_ the case, such as assigning multiple values to multiple targets: # Package up y and x into a tuple # Then unpack the tuple into two names x, y = y, x ChrisA -- https://mail.python.org/mailman/listinfo/python-list
