数据类型¶
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,
dict, list, set and frozenset, and
tuple. The str class is used to hold
Unicode strings, and the bytes and bytearray classes are used
to hold binary data.
