Python List count() Method

Python count() method returns the number of times element appears in the list. If the element is not present in the list, it returns 0. The examples and syntax is described below.

Let's see some examples of count() method to understand it's functionality.

Python List count() Method Example 1

It is a simple example to understand how a count method works.

# Python list count() Method
# Creating a list
apple = ['a','p','p','l','e']
# Method calling
count = apple.count('p')
# Displaying result
print("count of p :",count)

Output:

count of p : 2

Python List count() Method Example 2

If the passed value is not present in the list, the method returns 0. See the example below.

# Python list count() Method
# Creating a list
apple = ['a','p','p','l','e']
# Method calling
count = apple.count('b')
# Displaying result
print("count of b :",count)

Output:

count of b : 0

Python List count() Method Example 3

Python count() method can also be used to check whether an element is duplicate in the list or not. The below example checks the duplicacy of the element in the list.

# Python list count() Method
# Creating a list
apple = ['a','p','p','l','e']
# Method calling
count = apple.count('p')
# Displaying result
if count>=2:
    print("value is duplicate")
print("count of p :",count)

Output:

value is duplicate
count of p : 2
