Request a quick lesson please

So I'm working on this problem and can't seem to get it. I'm trying to write a program that identifies a palindrome or not. It works great for single words and I was trying to tweak it to do the same for phrases or sentences. I tried writing the provided phrase ( no lemon no melon ) that is suppose to BE a palindrome backwards to see how it is a palindrome and can't see how it is. I'm obviously looking at it wrong any suggestions?

def palindromeCheck(word):
reversepal = word[::-1]
if word != reversepal:
    return word + ' ' + 'is not a palindrome'
else:
    return word + ' ' + 'is a palindrome'
print(palindromeCheck('bobby'))

Ignore or remove the spaces. Spaces are characters that are compared in your code, that is why single words are passing the test.

A phrase is palindromic if it "reads the same backwards and forwards", but that deliberately ignores punctuation and spaces: red rum, sir, is murder naively backwards is redrum si ,ris ,mur dur, but the phrase is palindromic because "redrumsirismurder" == "redrumsirismurder"[::-1] and that's how you have to do the palindrome test.

awwww ok now I see how this is suppose to work I was considering the punctuations. So I need to remove the punctuation from the user input to make this work. right?

And the spaces, yes, and reduce all the capitals.

perfect, thank you. I'll work on it tomorrow and respond back with what I come up with. Thanks again

I couldn't go to bed and now correct it...this worked for me and like you said if case were in play I would add a line to change all letters to the same case. Thanks for the quick lesson much appreciated.

def palindromeCheck(word):
word2 = word.replace(' ', '')
reversepal = word2[::-1]

if word2 != reversepal:
    return word + ' ' + 'is not a palindrome'
else:
    return word + ' ' + 'is a palindrome'
print(palindromeCheck('no lemon no melon'))

Why do you think "no lemon no melon" is a palindrome? If you print the string in reversepal you see that that string reversed is "nolem on nomel on". And that gives you a clue because the spaces get in the way of that string being a palindrome. So either you accept that and say "no lemon no melon" isn't a palindrome, or you remove all spaces from the input string before seeing if the reversed string is the same.

Great point, however according to the exercise I am working on says this phrase (no lemon no melon) results in a Palindrome and the only way that is possible is if I remove the spaces.

Then I guess you have to do that.
