This will output 5, which is the number of elements in the list. You could also use collections.Counter() for counting the items in list from collections import Counter my_list = [1,2,3,4,5,5,5,5,5,5] count = Counter(my_list) print(count) Try it Yourself » Copy this wil...
list1=[1,2,3,4,1,4,3,2,2,1,5] print("List:",list1) print("Count of 2 in list1:",list1.count(2)) Output: List: [1, 2, 3, 4, 1, 4, 3, 2, 2, 1, 5] Count of 2 in list1 3 That’s all about Python count items in the list. Was this post helpful? Let us...
For instance, in Excel, the COUNT function can quickly tally the number of non-empty cells in a column containing numeric values. Similarly, in programming languages like Python, there are equivalent "count" functions to determine the number of items in a list or a string.In summa...
Approach:Convert the given list into a set using theset()function. Since a set cannot contain duplicate values, only the unique values from the list will be stored within the set. Now that you have all the unique values at your disposal, you can simply count the number of unique values ...
