That's not what I said. I said all expressions *evaluate to* pointers. As for the specification, it doesn't make use of the word "pointer:" <URL: https://docs.python.org/3/reference/simple_stmts.html#assignme nt-statements> Instead, it uses (English) expressions like: is bound to the object is rebound when talking about "names" (aka variables). It also uses circular definitions when talking about dicts and lists: That object is then asked to assign the assigned object to the given attribute the sequence is asked to assign the assigned object to its item with that index. The (English) expression: The name is bound to the object. is just another way of saying: A pointer to the object is stored in the variable. Of course, I'm using terminology that is not conventional in Python circles. However, I'm doing it to demonstrate that there's nothing particularly different between Python's assignment semantics and those of, say, Pascal. Python's assignment semantics are wholly contained by those of Pascal. Marko -- https://mail.python.org/mailman/listinfo/python-list
