- '''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
