9. How to Use Basic Queue Operations in Python

Learning how to use queues in Python can be a bit tricky, but don't worry! Let's break it down into simpler parts.

1. What is a Queue?

   • A queue is a way to organize things that you want to use. It works on the FIFO rule. FIFO means "First In, First Out." This just means that the first item you add is the first one you take out. It can be confusing when you first start learning!

2. Queue Operations:

   • Enqueue (add): This means putting an item at the back of the queue. If you use a basic list, this can be slow because the computer has to work hard to make space.
   • Dequeue (remove): This means taking the item from the front of the queue. When you do this with a list, it can be slow too because the items need to shift forward.

3. Ways to Make It Easier:

   • You can use something called collections.deque. This is great because it allows you to add and remove items quickly.
   • You could also make your own queue by using lists, but just remember that it might not be as fast.

With some practice, you'll find that understanding queues and how to use them in Python will become much easier!
