Python List count() (with Code Visualization)

Python List count()

In this tutorial, we will learn about the Python List count() method with the help of examples.

The count() method returns the number of times a specified item appears in the list. Here's a quick example:

models = ['Claude', 'ChatGPT', 'Gemini', 'ChatGPT']

count = models.count('Gemini')
print(f'Count of Gemini: {count}')

count = models.count('ChatGPT')
print(f'Count of ChatGPT: {count}')

Output

Count of Gemini: 1
Count of ChatGPT: 2

count() Syntax

The syntax of count() is:

result = my_list.count(item)

Arguments

count() takes a single argument, the item whose count is to be found.

Return Value

count() returns an integer (the number of times the item appears).

Example: count() in Nested lists

groups = [[1, 2], [1], [1, 2], [2, 3]]

count = groups.count([1, 2])
print(f"Count of [1, 2] is: {count}")

count = groups.count([1])
print(f"Count of [1] is: {count}")

count = groups.count(1)
print(f"Count of 1 is: {count}")

Output

Count of [1, 2] is: 2
Count of [1] is: 1
Count of 1 is: 0
