A palindrome is a word that reads the same forwards and backwards, such as civic, racecar, or Hannah. One way to construct strings of letters that read the same forwards and backwards (which I hesitate to call palindromes since most are not even words) is to start with the empty string, '', and repeatedly add the same letter to the front and back, for example: '' 'nn' 'anna' 'hannah'. (To get a string of odd length, you start with a one-letter string.) Write Python code to produce (pseudo-)palindromes in this way. Have it so that it produces only palindromes of even length. (So, start with the empty string.) Use a while loop. Prompt for and input a letter at each iteration (which goes at both ends of the string generated so far). Enter an empty string (which counts as False) to stop.
