palindrome(“1 eye for of 1 eye.”);

Hello. I have been trying to solve this challenge but the only mistake the code says I have made is the one above: the sentence “1 eye for of 1 eye.” should return false. Instead it returns true, but I think the sentece is actually a palindrome if we consider the parameters of the challenge. So what am I doing wrong here? Thank you in advance for your reply.


You shouldn’t be removing numbers from the string, "You’ll need to remove all non-alphanumeric characters ". Numbers are alphanumeric.


Thank you very much. It was really helpful.Have a nice day.
