You should upgrade and read the
Python documentation for the current stable release.
8. 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,
dict
, list
, set
(which along with
frozenset
, replaces the deprecated sets
module), and
tuple
. The str
class can be used to handle binary data
and 8-bit text, and the unicode
class to handle Unicode text.
