Now obviously divided by zero is a math error, so when I save and run this, we can see that the program crashes and exits with this division by zero error message. Now, this is a pretty bad experience for users and we can do a much better job of handling errors like this in our code by using exception handling. So let's close the terminal. So let's rewrite this by using exceptions. So I'm going to comment that out. I'm going to write try, and then I'm going to do my formula again. Okay. And then I'm going to write except,…
