The Python count () method calculates how many times a particular item appears in a list or string. count () takes one argument: the value you want to search for in the list. The count () method is added to the end of a list or string object.

You may want to know how many times a specific value appears in the list or string. For example, let’s say you are a wholesaler. You might want to know how many orders a specific customer has placed in the past six months.

The Python count () method can be used to count the number of times a particular item appears in a list or string. When used with a string, the count () method counts the number of times that a substring occurs in a larger string. When count () is used with a list, the method counts the number of occurrences of a specified value in a list.

In this article, we’ll see how to use the count () on lists and strings.

Python count () function

The Python count () function calculates how many times a value is displayed in a list or in a string. Returns the number of times the value is displayed as an integer.

Here is the syntax of the count () function:

Our code counts how" Lewis " appears multiple times in our list.

You can see that the count () method is appended after a list value in this example. count () does not take a list as an argument. The count () method expects you to pass the value you want to search for in a list or string as an argument.

Python: count items in list

For example, let’s say you are a salesperson for a local tea business. You might want to know how many times English Breakfast tea has been sold to a particular customer in the past month. This will allow you to assess the demand for tea.

You can use a count () method on a list of tea orders placed in the last month by a particular customer to assess the demand. Here is an example of a program that does this:

In the first line of code, we declare a Python array that stores all of the orders that a particular customer has placed in the last month. count () to calculate how many times English Breakfast tea has been ordered by the customer.

Finally, we print the result of our count () to the console. To do this, we use a Python print () statement . Our code returns the total number of times the English Breakfast item appears in the list. The result is here 3.

The count () function in Python can be used on a list of numbers. Let’s say you are a fourth grade teacher who wants to know how many ten year olds there are in your class. You can calculate this information using the following code:

We count the item four times in our list. The program returns: 4.

The count () method can count the number of occurrences of a substring in a larger string . The Python count () string method searches for a string. Returns a value equal to the number of times an substring occurs in the string.

The syntax of the built-in count () function is as follows:

The count () string method accepts three parameters:
