Write a program that prompts the user for a word or phrase, and determines if the entry is a palindrome. A palindrome is a word
vekshin1

Answer:

Explanation:

The following code is written in Python. It asks the user for an input. Then cleans the input using regex to remove all commas, whitespace, and apostrophes as well as making it all lowercase. Then it reverses the phrase and saves it to a variable called reverse. Finally, it compares the two versions of the phrase, if they are equal it prints out that it is a palindrome, otherwise it prints that it is not a palindrome. The test case output can be seen in the attached picture below.

import re

phrase = input("Enter word or phrase: ")

phrase = re.sub("[,'\s]", '', phrase).lower()

reverse = phrase[::-1]

if phrase == reverse:

   print("This word/phrase is a palindrome")

else:

   print("This word/phrase is NOT a palindrome")
