Build a Palindrome Checker Project - Build a Palindrome Checker

Tell us what’s happening:

The code looks right, passes the conditions and gives the right output for different scenarios. But I’m unable to pass the test and move ahead.

Remove the double quotation marks ( "" ) around the text in the result messages.

To be more clear,

The result messages should be:
A is a palindrome
1 eye for of 1 eye. is not a palindrome

Yours is currently are:
"A" is a palindrome
"1 eye for of 1 eye." is not a palindrome
