The modules described in this chapter provide a variety of specialized data types such as dates and times, fixed-type arrays, heap queues, synchronized queues, and sets.
Python also provides some built-in data types, in particular,
dict, list, set and frozenset, and
tuple. The str class is used to hold
Unicode strings, and the bytes class is used to hold binary data.
