Palindromes
Next, you are committed to finding any peculiarity in the words included in the movie review dataset. A palindrome is a sequence of characters that can be read the same backward as forward, for example: Madam or No lemon, no melon. You realize that some funny movie names can have this characteristic. You want to make a list of all movie titles that are funny palindromes but you will start by analyzing one example.
In python, you can also specify steps by using a third index. If you don't specify the first or second index and the third one is negative, it will return the characters jumping and backward.
The text of a movie review for one example has already been saved in the variable movie. You can use print(movie) to view the variable in the IPython Shell.
