Hey guys, welcome back to 100 Days of Code.

2
00:00:03,910 --> 00:00:05,650
Today is day 4,

3
00:00:05,860 --> 00:00:10,060
and we're going to be focusing on randomization in Python,

4
00:00:10,420 --> 00:00:12,850
and we're going to be learning about Python lists.

5
00:00:13,270 --> 00:00:17,590
Now randomization in any sort of programming language is really,

6
00:00:17,590 --> 00:00:20,770
really useful because if we want to create a game,

7
00:00:20,770 --> 00:00:24,040
if we want a program to do something different each time,

8
00:00:24,400 --> 00:00:27,730
then we need to introduce a little bit of randomness, right?

9
00:00:28,120 --> 00:00:32,380
So we're going to be looking at using the random module in order to achieve

10
00:00:32,380 --> 00:00:35,050
this. And by the end of today,

11
00:00:35,080 --> 00:00:39,640
you will have learned enough to be able to build this Rock-paper-scissors game.

12
00:00:40,150 --> 00:00:45,150
So it starts out asking you, the user, type 0 for rock, 1 for paper or 2

13
00:00:45,970 --> 00:00:49,450
for scissors. So I'm going to go forward with 0 for rock.

14
00:00:50,080 --> 00:00:54,160
And it shows me using ASCII art that this is what I chose, rock.

15
00:00:54,610 --> 00:00:59,500
And then the computer chose scissors and rock beats scissors. So I win.

16
00:01:00,010 --> 00:01:02,230
Now you can run this as many times as you want.

17
00:01:02,620 --> 00:01:06,460
If I choose paper and the computer chooses rocks, then I win.

18
00:01:06,760 --> 00:01:10,390
If I choose paper and the computer chooses paper than it is a draw.

19
00:01:10,960 --> 00:01:15,160
But if I choose paper and the computer chooses scissors, then I lose.

20
00:01:15,610 --> 00:01:17,140
So this is a pretty simple game,

21
00:01:17,590 --> 00:01:20,710
but we're going to get the computer to play this game with us.

22
00:01:20,890 --> 00:01:25,840
And we're going to do that by learning about randomization, lists and a whole lot

23
00:01:25,840 --> 00:01:27,190
more. I hope you're ready.

24
00:01:27,520 --> 00:01:31,600
And once you are, then head over to the next lesson, and let's get started.
