8. Data Types — Python 3.4.10 documentation (original) (raw)
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, andtuple. The str class is used to hold Unicode strings, and the bytes class is used to hold binary data.
The following modules are documented in this chapter:
