1a). Write a PYTHON program that accepts a list of any length that contains a mix of non-negative integers and strings. The function should return a list with ONLY integers in the original list in the same order.

1b). Create a PYTHON program that checks to see whether a string that is passed as a parameter is a palindrome. A palindrome is a string that reads the same backwards and forwards. For example, the string abba is a palindrome. The function in this program does the checking and returns a true or false outcome to the program.
