Python – Count the items with a specific value in the List

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.

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.

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.
