WHILE LOOP QUESTION
Towards the end of the video, why does Craig put while tickets_remaining >=1: instead of putting while tickets_remaining >0:? Thank you in advance.

The functionality would be identical with either code choice. There will often be more than one valid way to code something, and it's "programmer's choice". He may have chosen that intentionally because he felt it conveyed the purpose of the code better, or it might just have been the first thing he thought of.
Perhaps if we tag him here, Craig Dennis will drop by and let us know!

To add on to Steven, in a programmers view, it seems much nicer to say, "greater than, or equal to 1" over saying, "greater than 0". It makes the code much easier to read, edit, and maintain.
