I suggested a "mutable" attribute some time ago. This could lead to finally doing away with one of Python's FAQs: Why does python have lists AND tuples? They could be unified into a single type.
The main difference between lists and tuples is not mutability but usage: lists are for a (unknown) number of similar items (a list of messages, e.g.), tuples are for a (known) number of different items at fixed positions (an address is a tuple of (country, city, street address), for example).
And tuple doesn't have append, extend, remove, ... methods. Victor
