The collections module implements some specific data types, which can replace the built in data types commonly used in python, such as dict, list, set, tuple. in short, the basic data types are further processed. main types: this module is only introduced by deque, counter, ordereddict, defaultdict. 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. A container is an object used to store various items and give the means to retrieve and iterate over the enclosed objects. tuple, list, dictionary, and more built in containers are available. also, the collections module has highly specialized and efficient container data types such as namedtuple (), deque, ordereddict, counter, and so on that. Now that you’ve learned the defaultdict, let’s learn some more useful data structures that are all found in the collections module. let’s start with the counter class. so, let’s try to solve a question not using the counter class and see how it…. Collections is a module in the standard library that implements containers of alternative data types. for example, counter is a collection of elements that are stored as dictionary keys, and their counters are stored as dictionary values: from collections import counter a = counter('blue') b = counter('yellow') print (a) print (b) print ((a b.

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. Counter. the collections module also provides us with a neat little tool that supports convenient and fast tallies. this tool is called counter . you can run it against most iterables. let’s try it out with a string! in this example, we import counter from collections and then pass it a string. this returns a counter object that is a subclass. Introduction. collections in python are containers that are used to store collections of data, for example, list, dict, set, tuple etc. these are built in collections. several modules have been developed that provide additional data structures to store collections of data. one such module is the python collections module.
