Well hello there, Craig here. 0:09

How's it going? 0:11

In this workshop, we're gonna practice using some of those python muscles that 0:12

you've been building up. 0:16

When you're just getting started with the language, 0:18

sometimes it's hard to find a way to apply the skills that you've been learning. 0:19

It's hard to see how the pieces that you've been picking up all snap together 0:24

to form a program. 0:27

Now I'm going to assume for this practice session, that you know how to use 0:28

variables, take input from a user and output things to the screen. 0:32

If you don't, please check the teacher's notes for 0:36

where you can learn those things. 0:39

Believe it or not, but with just those skills, input, output, and 0:41

variables, you can write a pretty fun game. 0:45

Now, I'm not sure if you've done one of these before, but 0:48

Mad Libs has been declared the world's best word game. 0:53

The way it works is this. 0:57

There's two players, and one player has a page like this. 0:59

And see how it has blanks that are labeled with different parts of speech like 1:02

a noun, an adjective, or a verb? 1:05

The first player prompts the second player for 1:07

words that match those parts of speech and fills in the blanks with their answers. 1:10

Then the first player reads the results aloud and hilarity ensues. 1:14

So we're gonna do it. 1:19

We're gonna build MadLibs in Python. 1:20

So let's go back to the workspace. 1:23

Go ahead and launch this and you will see here I have a file called madlibs.py. 1:24

So I'm gonna open that up. 1:28

And you'll notice here that I've made a template for us. 1:31

Something that you might not have encountered yet are these pound signs or 1:35

hashtags, as the kids are calling them these days. 1:39

What this does is this is a comment, and 1:42

this tells Python to ignore all of the characters on the line and after it. 1:44

So what we can do is we can use this to write English, just like I did here. 1:48

It's a way to be able to communicate to readers of your code. 1:54

You'll end up leaning on these quite a bit in the future. 1:59

Comments can also be used to make note of things that you'd like to do later, 2:02

sort of like a to do list. 2:06

And typically the way that you do it, 2:08

kinda the format that's come about is this to do, in all caps. 2:09

TODO colon and then what it is. 2:13

It's kinda like a standard. 2:15

So I've left some to do's for you to do. 2:18

But first off, I'd like you to prompt the user for the various parts of speech, 2:22

like the verb and the noun and the adjective. 2:27

And then store each of the responses in a variable. 2:32

And then the second to do, I would like you to output 2:35

that template with the words that the user just filled out. 2:40

Got it? 2:44

Don't worry, you got this. 2:45

You have all the skills that you need to achieve this, and it's totally fine for 2:47

this to be a bit of a struggle. 2:52

It's kinda like no pain no gain, but for your brain. 2:53

So in the next video I'll show you how I did it. 2:57

In fact, you know what? 3:00

I've already done the practice, so 3:02

let me show you what my final product looks like so you can try to recreate it. 3:04

So here, I'm gonna jump over to mine. 3:07

I'm not going to show you my code, nice try. 3:09

So say python and the name of that program is madlibs.py. 3:12

So this is what it looks like when it runs. 3:15

So it says, please enter a verb. 3:17

Now remember I don't know what that template is. 3:18

So dance, I don't know. 3:20

Enter a noun, let's see, dinosaur. 3:23

That's a good noun. 3:25

And an adjective. 3:27

How about wacky? 3:28

I enjoy practice, I find it helps me to dance better, I wish. 3:30

Without practice, my dinosaur probably wouldn't even work. 3:34

My codes gonna get more wacky every single day. 3:36

See, fun, right. 3:39

All right, so you can do this, right? 3:41

And again, don't beat yourself up if you can't quite get it, 3:43

I want you to really give it a try. 3:46

And remember, I'll show you how I did it in the next video, but 3:48

don't skip ahead, give it a go, you ready? 3:50

You got this. 3:53
