Using the Python collections Counter can count the key-value pairs in an object, also called a hashtable object. You have to import the counter tool From collections module in python.
from collections import Counter Counter(list)
The Counter holds the data in an unordered collection, just like hashtable objects. The elements here represent the keys and the count as values.
From collections import Counter in Python
Simple example code import Counter. You can simply import it the same as other modules.
Python Counter takes in input a list, tuple, dictionary, and string, which are all iterable objects, and it will give you output that will have the count of each element.
from collections import Counter list1 = ['x', 'y', 'z', 'x', 'x', 'x', 'y', 'z'] res = Counter(list1) print(res) print(type(res))
