python program using while loop and if statement

.Practice string manipulation with loop. Write a function, named testTwoSame, that accepts a string as argument and returns True if the passed-in string is non-empty and contains 2 same characters in a row, False otherwise. You should write a loop to implement such a functionality. You might want to use the following test cases: Function call testTwoSame (") testTwoSame ("a") testTwoSame ("aa") Return value False False True testTwoSame (" xts") True testTwoSame ("seattle) True
