8.Data Types¶
The modules described in this chapter provide a variety of specialized datatypes such as dates and times, fixed-type arrays, heap queues, synchronizedqueues, and sets.
Python also provides some built-in data types, in particular,dict,list,set andfrozenset, andtuple. Thestr class is used to holdUnicode strings, and thebytes class is used to hold binary data.
The following modules are documented in this chapter:

datetime— Basic date and time types - 8.2.
calendar— General calendar-related functions - 8.3.
collections— Container datatypes - 8.4.

bisect— Array bisection algorithm - 8.7.
array— Efficient arrays of numeric values - 8.8.
