Submitted by razormist on Thursday, March 13, 2025 - 23:35.

In this tutorial, we’ll learn how to program “How to Count Frequencies in a List in Python.” The objective is to accurately count the frequency of each element in a list. This tutorial will guide you through the process step by step to ensure you achieve accurate frequency counting. So, let’s get started!

This topic is straightforward to understand. Just follow the instructions I provide, and you’ll complete it with ease. The program I’ll demonstrate will show the correct way to count the frequency of elements in a list. So, let’s dive into the coding process!

Getting Started:

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.

Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.

from collections import defaultdict
 
my_list = ['php', 'javascript', 'python', 'python', 'c++', 'python']
 
while True:
    print("\n================= Count Frequencies in a List =================\n")
 
    print("My list:", my_list)
 
    frequency_count = defaultdict(int)
 
    for item in my_list:
        frequency_count[item] += 1
 
    print("\nTotal frequencies:", dict(frequency_count))
 
    opt = input("\nDo you want to try again? (yes/no): ").strip().lower()
 
    if opt == 'no':
        print("Exiting program...")
        break
    elif opt != 'yes':
        print("Invalid input. Please enter 'yes' or 'no'.")

This Python program counts the frequency of each element in a list using defaultdict from the collections module, repeatedly displays the frequencies, and asks the user if they want to run it again, handling "yes" or "no" inputs.
