Data Types
**********
The modules described in this chapter provide a variety of specialized data
types such as dates and times, fixed-type arrays, heap queues, double-ended
queues, and enumerations.
Python also provides some built-in data types, in particular,
:class:`dict`, :class:`list`, :class:`set` and :class:`frozenset`, and
:class:`tuple`. The :class:`str` class is used to hold
Unicode strings, and the :class:`bytes` and :class:`bytearray` classes are used
to hold binary data.
The following modules are documented in this chapter:
