Test your knowledge: Python Loops

Review

1. How does the lesson say to choose between for and while?

   for walks what you can see, a collection with a known end, while while repeats until something changes. The lesson's while carried two facts, the bread and the queue, and stopped when either ran out.
2. A queue needs numbering, human-style, from one. What does the lesson reach for?

   enumerate supplies the position alongside the item, and start=1 shifts it to human numbering, no counter to initialize or forget. It printed the lesson's numbered queue in one readable line.
3. The lesson's while condition read loaves > 0 and served < len(queue). When does the loop stop?

   A while condition may carry several facts, and the loop stops when the whole conjunction goes false, which happens as soon as either fact fails. One line stated both exits: no bread, or no one left to serve.
4. What is the difference between break and continue?

   break ends the loop on the spot, the exit for a finished search, while continue abandons the current iteration and moves to the next, the exit for an uninteresting item. Use them where they read best, the lesson says.
5. What did enumerate(queue, start=1) buy the example?

   start=1 numbers the walk from one, which is what a person reading a receipt expects, and the position arrives as a value rather than a counter the body maintains. Fewer moving parts, fewer ways to be off by one.
