    Hi, I'm Craig and I'm a developer. 0:08
    In this course, we're going to discuss a built-in Python data type known as a list. 0:11
    Now, lists are a powerful data structure that allow you to group multiple values 0:16
    together in a single container. 0:20
    But before we get started, let me list a couple of things 0:22
    just to make sure that you're comfortable with your learning environment. 0:26
    Now first, on our things to talk about list, 0:29
    I'd like to make sure that you've taken the prerequisites for this course. 0:31
    I want to make sure that we're on the same page and 0:34
    that you know what I'm talking about. 0:35
    Our next item that I'd like to remind you about is that there are speed 0:38
    controls on the video. 0:41
    Feel free to slow me down or speed me up. 0:42
    And also, don't forget that you can pause and rewind me whenever you need to. 0:46
    You're in complete control. 0:49
    Next item. 0:52
    There are teacher notes attached to most videos. 0:52
    Make sure to check them out. 0:55
    Lots of great information is tucked away in there. 0:56
    Our final item on our things to talk about list is, 0:59
    there is a wonderful and uber friendly community here on Treehouse. 1:02
    Ask questions and answer questions. 1:06
    I promise that you'll learn a ton just hanging out there. 1:08
    Nothing helps solidify your knowledge like answering a question. 1:11
    So we just ran through a handy list of things that I wanted to talk to you about. 1:14
    We use lists all the times. 1:18
    There's grocery lists, to-do lists, even lists of products on web pages. 1:19
    Python provides a very clear and easy way to create lists. 1:23
    In this course, we'll learn how to create, combine, manipulate, and 1:27
    use lists to our advantage. 1:30
    By the end of this course, we'll build an interactive console application 1:33
    that will prompt the user to build a grocery list. 1:37
    You can take this concept and build any sort of other list that you can think of. 1:40
    Sound fun? 1:43
    Let's get started. 1:44
