1
00:00:00,180 --> 00:00:04,060
I've got and a boon to computer here I'm going to start Python 3.

2
00:00:04,170 --> 00:00:06,970
What type is true.

3
00:00:06,990 --> 00:00:09,350
Be careful when I press enter here.

4
00:00:09,360 --> 00:00:10,750
What's gonna happen.

5
00:00:12,260 --> 00:00:13,840
Notice I get an error.

6
00:00:13,850 --> 00:00:18,230
True is not defined what type however is true.

7
00:00:18,230 --> 00:00:19,860
Written like that.

8
00:00:20,030 --> 00:00:22,790
Notice it's a Boolean true or false.

9
00:00:22,820 --> 00:00:24,970
What type is false.

10
00:00:26,430 --> 00:00:30,210
Notice error but change that to uppercase.

11
00:00:30,210 --> 00:00:31,260
It's a boolean.

12
00:00:31,380 --> 00:00:34,940
So as an example is one equal to one.

13
00:00:34,980 --> 00:00:35,920
That's true.

14
00:00:36,060 --> 00:00:37,500
Is one equal to two.

15
00:00:37,500 --> 00:00:39,360
No that's false.

16
00:00:39,360 --> 00:00:42,460
Is one equal to two minus one.

17
00:00:42,510 --> 00:00:43,770
That's true.

18
00:00:43,860 --> 00:00:48,880
Billions allow us to determine if something is true or false and then do something accordingly.

19
00:00:48,910 --> 00:00:54,800
So as an example I'm in England at the moment a boolean that I would use is.

20
00:00:54,870 --> 00:00:56,170
Is it raining outside.

21
00:00:56,190 --> 00:00:56,690
True.

22
00:00:56,730 --> 00:00:57,540
Take a umbrella.

23
00:00:57,540 --> 00:00:58,430
False.

24
00:00:58,440 --> 00:01:00,350
Don't take an umbrella.

25
00:01:00,360 --> 00:01:02,350
Well in England you probably want to take it with you.

26
00:01:02,490 --> 00:01:04,680
But on a day like today it's sunny.

27
00:01:04,680 --> 00:01:07,920
No rain is predicted so I don't need an umbrella.

28
00:01:07,920 --> 00:01:08,580
It's false.
