How to Remove Duplicate Words from a Sentence Using Regular Expressions in Python
In this tutorial, we’ll learn how to program “How to Remove Duplicate Words from a Sentence Using Regular Expressions in Python.” The objective is to safely remove all duplicate words from a sentence. This tutorial will guide you through the process step by step. 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 illustrate the proper way to find and remove all duplicate words from a sentence. 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.- import re
- def removeDuplicateWords(input):
- regex = r'\b(\w+)(?:\W+\1\b)+'
- return re.sub(regex, r'\1', input, flags=re.IGNORECASE)
- while True:
- print("\n================= Remove Duplicate Words from a Sentence =================\n\n")
- my_string = input("Enter your sentence: ")
- print(removeDuplicateWords(my_string))
- 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 program removes duplicate words from a sentence using regular expressions. It detects repeated words regardless of case and replaces them with a single occurrence. The user can input a sentence, see the cleaned-up result, and choose to try again or exit the program.
Output:
