def palindrome( s):write a method that returns True if the string s is a palindrome, i.e., the letters are symmetric around the midpoint of the string. It should return False, if the string is not a palindrome. For example, "asdffdsa" and "asdfdsa" are palindromes where as "asdfgh" is not.
2. Write a function with the heading def
palindrome(x) that determines if the list x is a palindrome.
3.. Given a list x that has at least m elements and a
list y that has at least n elements, write a function with the
heading def addThem(x, y, m, n) that returns an array that has as its
first m elements the first m elements of x and as its next n elements
the first n elements of y.
4. Write a function with the heading def pattern(n): that produces the following triangle:
x xx xxx xxxx xxxxx xxxxxx xxxxxxx xxxxxxxxwhere the bottom line has n x's.
5. Write a function def sum(x): that adds and returns the sum of all the elements in the list x.
