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.
