Python’s collections: A Buffet of Specialized Data Types
Python’s collections module provides a rich set of specialized container data types carefully designed to approach specific programming problems in a Pythonic and efficient way. The module also provides wrapper classes that make it safer to create custom classes that behave similar to the built-in types dict, list, and str.
Learning about the data types and classes in collections will allow you to grow your programming tool kit with a valuable set of reliable and efficient tools.
In this tutorial, you’ll learn how to:
- Write readable and explicit code with
namedtuple - Build efficient queues and stacks with
deque - Count objects quickly with
Counter - Handle missing dictionary keys with
defaultdict - Guarantee the insertion order of keys with
OrderedDict - Manage
