Why doesn't the teacher just use "elif" in this video?

In this video: https://teamtreehouse.com/library/branch-and-loop

We make a ticket machine. Skip to the end of the video and see the code.

Please answer why the teacher does not use "elif" after the first "if" statement, and instead he chooses to use "else:"

I used elif instead and the program runs and completes fine. Also it makes my final program require less writing.

Why did the teacher use "else:"? Is it a better choice than "elif" in this situation?

Can you post your code? I would say typically an else would require less code since there is no condition to consider. If we are talking about the same thing then anything but y or Y would be handled for 'should proceed' by else.

Thanks it makes sense. Because he used "else:" he didn't have to write the same code twice to account for "n" or "N" being an answer as literally anything other than "y" or "Y" is treated as a false boolean. Saves time and even accounts for typos.

I appreciate the explanation.

P.S. My code was almost the same as his except I just used "elif" and repeated the "if" statement but as you said neither the teacher or I would have needed to if I had just used "else:" instead.
