Use python collections

Python collections is the container data type, namely, lists, collections, tuples, dictionaries. The Collections module provides high-performance data types that enhance the code, making the work simpler and easier. It also provides many features, which are demonstrated using the Counter () function below.

The Counter () function takes an iterable object, such as a list or tuple, and returns an Counter dictionary. The key of the dictionary is the only element that exists in the iterator, and the value of each key is a count of the number of times that element appears in the iterator.

To create a Counter object, pass an iterative (list) to the Counter () function as follows.

Fromcollections import Countercount = Counter (['count: 3,' Counter: 2, 'Counter: 2,' averse: 1}) this is the end of the article on "how to use python collections".
