As python allows duplicate elements in a list we can have one element present multiple Times. The frequency of elements in a list indicates how many times an element occurs in a list. In this article we use the Counter function of the collections module to find out the frequency of each item in a list.
Syntax
Syntax: Counter(list) Where list is an iterable in python
Example
The below code uses the Counter() to keep track of frequency and items() to iterate over each item in the result of counter function for printing in a formatted manner.
from collections import Counter list = ['Mon', 'Tue', 'Wed', 'Mon','Mon','Tue'] # Finding count of each element list_freq= (Counter(list)) #Printing result of counter print(list_freq) # Printing it using loop for key, value in list_freq.items(): print(key, " has count ", value)
Output
Running the above code gives us the following result −
Counter({'Mon': 3, 'Tue': 2, 'Wed': 1})
Mon has count 3
Tue has count 2
Wed has count 1
