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.

Your code so far

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
