8. 数据类型¶
本章节描述的模块提供了一系列专门的数据类型例如日期与实践，固定类型的数组，堆队列，同步队列与集合。
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.
