Count Items in List with a Given Value
To count the number of occurrences of items with a specific value in a list, you can call count() function on the list with the specific item passed as argument to the count() function.
Syntax of count()
Following is the syntax of count() function.
n = list.count(item)count() function returns the number of occurrences of the item in this list.
Examples
1. Count occurrences of the item “74” in given list
In the following example, we take a list of numbers in mylist, and find the number of occurrences of the item 74 in the list.
Python Program
mylist = [6, 74, 62, 85, 62, 62,74]
item = 74
n = mylist.count(item)
print(f'{item} occurred {n} times in the list.')Output
74 occurred 2 times in the list.The count() function takes exactly one argument.
2. Count occurrences of the item “apple” in given list
In the following example, we take a list of strings in mylist, and find the number of occurrences of the item "apple" in the list.
Python Program
mylist = ['apple', 'banana', 'cherry', 'apple', 'apple']
item = 'apple'
n = mylist.count(item)
print(f'{item} occurred {n} times in the list.')Output
apple occurred 3 times in the list.Summary
In this tutorial of Python Examples, we learned how to count the number of times an item is present in a given list.
