You want a dictionary. Python dictionaries map keys to values (in other languages, these data structures are known as hashes, maps, or associative arrays). The keys will be the dates; the values will depend on whether or not you have multiple messages for one date. If the dates are unique (which, looking at your data, is probably not true), then each item in the dictionary can be just one (who, message) tuple. If the dates are not unique, then you'll have to manage each item of the dictionary as a list of (who, message) tuples. And before you ask: no, dictionaries are *not* sorted; you'll have to sort a separate list of the keys or the items at the appropriate time.
