Introduction
This module implements specialized container datatypes providing alternatives to Python’s general purpose built-in containers, dict, list, set, and tuple.
What types does it offer?
Following are the most commonly used special container types of collections module,
Name
Purpose
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
deque
list-like container with fast appends and pops on either end
namedtuple
factory function for creating tuple subclasses with named fields
And...
We can also implement a custom container type like OrderedCounter using the container types provided by collections module.
The next series of posts will dive deep into the above mentioned container types provided by collections module.
Stay Tuned !
