Question

Write a python program that contains a hardcoded string and checks whether it is a palindrome (the same forwards as backwards). If it is then display “It is a palindrome”, otherwise display “It is not a palindrome”. A hardcoded string is simply a string defined in your program, for example: my_string = “Hello” Some sample palindromes to use are: A car, a man, a maraca Desserts, I stressed Madam, I’m Adam You will need to strip out any punctuation such as commas and apostrophes. Luckily, there’s a function that will allow us to replace (hint) a particular substring with anything (including the empty string – “”). Try having a list of punctuation characters, or a string of them all, and checking each character in the original string against that list.

thanks for the question, here is the updated code in python. all lines are commented so that you can understand and follow the code

let me know for any questions or changes

# string to check
my_string='majA car, a man a maraca jam'
# list of common punctuations
punctuation_list=['!','@','#','\'','-','_','\"','^','%','*','(',')','+','+','{','}',' ',',']
# will store the punctuations stripped out string
cleaned_string=''
# will hold the reverse string
reverse_string=''
# convert all the letter to lower case
my_string_lower_case=my_string.lower()
# iterate over each letter in the string
for letter in my_string_lower_case:
    #if the letter is in the punctuation list we dont consider that letter
    if letter in punctuation_list:continue
    # build the cleaned string
    cleaned_string+=letter
    # build the reverse string
    reverse_string=letter+reverse_string
# print the cleaned string and reverse string
print('Cleaned :',cleaned_string)
print('Reversed:',reverse_string)
# compare both the cleaned and reverse string are same and print the message
if cleaned_string==reverse_string:
    print('It is a palindrome')
else:
    print('It is not a palindrome')
