In this tutorial, we will program 'How to Replace Multiple Words in Python.' We will learn how to replace multiple words. The objective is to teach you how to easily replace multiple words. 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 will be able to do it yourself with ease. The program I will show you covers the basics of programming to replace multiple words. I will do my best to provide you with a simple method for replacing multiple words. 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

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.

import re 
 
print("\n\n============= Replace Multiple Word =============\n\n")
 
test_str = 'I Love coding for Sourcecodester'
 
print("The original string is : " + str(test_str)) 
 
word_list = ["Love", 'coding', 'for'] 
 
repl_wrd = 'Code'
 
res = re.sub("|".join(sorted(word_list, key = len, reverse = True)), repl_wrd, test_str) 
 
print("String after multiple replace : " + str(res))

This script replaces multiple specified words in a given string with a new word. It constructs a regular expression pattern from the list of words to be replaced, ensuring that the longest words are matched first to avoid partial matches. It then replaces all occurrences of these words with the new word and prints the result.
