This module implements specialized container datatypes providing alternatives to Python’s general purpose built-in containers, dict, list, set, and tuple.
- namedtuple() factory function for creating tuple subclasses with named fields
- deque list-like container with fast appends and pops on either end
- ChainMap dict-like class for creating a single view of multiple mappings
- Counter dict subclass for counting hashable objects
- OrderedDict dict subclass that remembers the order entries were added
- defaultdict dict subclass that calls a factory function to supply missing values
- UserDict wrapper around dictionary objects for easier dict subclassing
- UserList wrapper around list objects for easier list subclassing
- UserString wrapper around string objects for easier string subclassing
