  • Python 1.6

    ...tuple made out of all arguments, but was undocumented. To append a tuple, use e.g. l.append((a, b, c)). The connect(), connect_ex() and bind() methods for sockets require exactly one argument. Previously, you could call s.connect(host, port), but this was undocumented. You must now write s.connect((host, port)). The str() and repr() functions are now different more often. For long integers, str() no longer appends a 'L'. Thus, str(1L) == '1', which used to be '1L';...

    ...tuple([iterable]) list([iterable]) type(object) or type(name_string, bases_tuple, methods_dict) The signature of type() requires an explanation: traditionally, type(x) returns the type of object x, and this usage is still supported.
