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.
The following modules are documented in this chapter:
