Do you need "else" after if statement

At 7:45 of the video - there are two if statements, however first one uses "else" and the second one doesn't, why is that?

An "else" is optional. Sometimes when a condition is not true, you don't need to do anything, so no "else" is needed.

And even when you do want to respond to a condition not being true, when the "if" code redirects program flow (such as with a "break", "return", or "raise") the "else" isn't necessary.
