Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})
For example, to connect to the DICT server on localhost, on a Unix system one can normally type: telnet localhost dict and then enter the command "help" to see the available commands.
