# count() Method for Lists in Python (2 Examples)

In this Python tutorial, you’ll learn how to apply the count() method to Python lists to return the frequency of the elements in this list.

The article contains the following content:

Let’s go straight to the examples.

## Exemplifying Data

We will be using the following data as an example for this tutorial.

`my_list = ['blue', 'green', 'red', 'blue', 'purple', 'yellow']`

As shown in the Python output, we have constructed a list object that contains 6 strings under the name my_list.

Let’s see how the count() method works using my_list in the following examples.

## Example 1: Apply count() Method to Obtain Frequency of Certain Element in List

This example illustrates the basic use of the count() method, which is extracting the number of occurrences of a particular element in a list. For demonstration, we will return the count of string “blue” in my_list.

```my_list.count('blue')
# 2```

As the previous output shows, our list contains the character string “blue” twice.

## Example 2: Apply count() Method to Obtain Frequency of Each Element in List

Imagine that we want to get the number of occurrences for each element in the list. In such a case, we can use the count() method inside a list comprehension to iterate through our list. Take a look at the following code.

```new_list = [[l, my_list.count(l)] for l in set(my_list)]
print(new_list)
# [['blue', 2], ['purple', 1], ['green', 1], ['yellow', 1], ['red', 1]]```

The output shows the new list that contains the lists of strings and their counts (i.e., 1 for green and so on) in my_list.

We can also create a dictionary using the dict() function.

```dictionary = dict((l, my_list.count(l)) for l in set(my_list))
print(dictionary)
# {'blue': 2, 'purple': 1, 'green': 1, 'yellow': 1, 'red': 1}```

The printed counts are the same as shown in the previous output, yet they are now stored in a dictionary instead of a list.
