Python- I'm supposed to determine if the string 'garden' contains a lowercase letter 'r' or uppercase letter 'R'. I have to use if/else or for loop to solve this problem. For some reason, my code won't run. Can someone explain what I'm doing wrong as well as provide with the proper source code. Thanks
