.. _datatypes: ********** 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, synchronized queues, and sets. Python also provides some built-in data types, in particular, :class:`dict`, :class:`list`, :class:`set` (which along with :class:`frozenset`, replaces the deprecated :mod:`sets` module), and :class:`tuple`. The :class:`str` class can be used to handle binary data and 8-bit text, and the :class:`unicode` class to handle Unicode text. The following modules are documented in this chapter: .. toctree:: datetime.rst calendar.rst collections.rst heapq.rst bisect.rst array.rst sets.rst sched.rst mutex.rst queue.rst weakref.rst userdict.rst types.rst new.rst copy.rst pprint.rst repr.rst
