PYTHON 3

CODE IS TESTED WITH JDK AND WILL KNOW WHEN USING FORBIDDEN CODE

 write a program called reversibleSentence

-- ask for a word from user
-- if word is the same read from left to right or right to left, then
-- print "the word is reversible", else
-- print "the word IS NOT reversible"

  HINT:

  The following program prints heo

for x in "hello":
    if x != "l":
        sentence = sentence + x
print(sentence)

% reversibleSentence.py
enter a sentence: anna
the word is reversible
% reversibleSentence.py

Answer 1

#get user input
word = input("Enter a word: ")

#string declaration
sentence = ""

#remove the special character
for character in word:
if character.isalnum():
sentence += character

#method to check word is reversible or not
def reversibleSentence(sentence):
revString = sentence[::-1]
for x, y in zip(sentence, revString):
if x != y:
print("the word IS NOT reversible")
return False
  
print("the word is reversible")   
return True

#method calling
reversibleSentence(sentence)
