How to Get Least Frequent Character in String using Python

In this tutorial, we will program 'How to Get the Least Frequent Character in a String using Python'. We will learn how to display the least frequent character(s) in a string. The objective is to automatically identify and display the least frequent character(s) in a given string. I will provide a sample program to demonstrate the actual coding process in this tutorial.

This topic is very easy to understand. Just follow the instructions I provide, and you can do it yourself with ease. The program I will show you covers the basics of programming to display the least frequent character in a string. I will do my best to provide you with a simple method for identifying and displaying the least frequent character. So, let's start with the coding.

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

from collections import Counter
 
 
test_str = "sourcecodester"
 
 
ret = False
 
 
while True:
        print("\n================== Get Least Frequent Character in String ==================\n\n")
 
 
 
        print ("Original String: " + test_str)
 
 
        res = Counter(test_str)
        res = min(res, key = res.get) 
 
 
        print ("The least characters in a string is : " + str(res))
 
        opt = input("\nDo you want to try again?(yes/no): ")
 
        if opt.lower() == 'yes':
                ret=False
        elif opt.lower() == 'no':
                ret=True
                print("Exiting program....")
 
        else:
                print("Please enter yes/no:")
                break
 
        if ret == False:
                continue

This script finds and displays the least frequent character in the string "sourcecodester". It repeatedly prompts the user to rerun the process or exit the program. Each time, it prints the least frequent character, allowing the user to choose whether to continue or exit based on their input.

Output:

There you have it we successfully created How to Get Least Frequent Character in String using Python. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
