Introducing the Practice

1:52 with Jay McGavren

Let's practice some basic Ruby to make sure that everything you've learned so far sticks. We'll review variables, as well as simple input and output.

To complete this practice, you'll need to use:

    Let's practice some basic Ruby to make sure that everything that you've learned 0:04
    so far sticks. 0:08
    We'll review variables, as well as simple input and output. 0:08
    If you're not familiar with these topics, 0:12
    check the Teacher's Notes attached to this video for links where you can learn more. 0:14
    We're going to ask you to build a simple Ruby program. 0:18
    Your program will play a fill-in-the-blank word game with the user. 0:22
    You'll prompt them for a noun, a verb, and so forth, just like this. 0:25
    So please enter a verb, jump. 0:30
    Please enter a noun, desk. 0:31
    Please enter an adjective. 0:33
    Let's say, quick. 0:35
    And another noun. 0:36
    Let's say, can. 0:38
    Then you'll use those stored words to fill in blanks in several sentences and 0:39
    print the completed sentences out. 0:43
    The resulting story will probably sound a little silly, and 0:45
    that's exactly the point of the game. 0:48
    It's pretty simple but it combines several fundamental programming steps. 0:49
    The formatting on your printed story may look a little strange. 0:54
    Don't worry about that while you're coding your solution. 0:57
    When I show you my solution, I'll also show you a new method you can go back and 0:59
    add to your program to clean up the output. 1:03
    I've attached a workspace to this video, 1:06
    which includes a game.rb starter file with instructions as Ruby comments. 1:08
    You should open the workspace now. 1:12
    You can either use our in-browser editor, or you can choose Download Workspace from 1:15
    the File menu, if you have Ruby installed on your computer. 1:19
    Write your code in the game.rb file and save your work. 1:23
    Then, switch to the terminal and type ruby game.rb. 1:26
    That will run your completed game. 1:31
    The game should begin prompting for words and print your story when it's done. 1:33
    I've linked to some videos in the Teacher's Notes, 1:38
    which you can refer to if you get stuck. 1:40
    After you've written your program, 1:41
    you can proceed to the next video where you can compare my solution to yours. 1:43
    Ready? 1:47
    Get started on your program. 1:48
    I'll show you my version in the next video. 1:49
