00:00:00,120 --> 00:00:03,940
On a boon to computer I'm going to start Python 3.

2
00:00:04,080 --> 00:00:06,860
What type is one two three.

3
00:00:06,960 --> 00:00:08,260
That's an integer.

4
00:00:08,340 --> 00:00:11,050
What type is one dot two three.

5
00:00:11,130 --> 00:00:13,010
That's a floating point number.

6
00:00:13,500 --> 00:00:16,350
Integers are whole numbers positive or negative.

7
00:00:16,350 --> 00:00:18,680
Floating point numbers have fractions.

8
00:00:18,750 --> 00:00:24,270
What type is a notice I get an error here saying that A is not defined.

9
00:00:24,480 --> 00:00:31,710
But if I say that A equals hello and then specify type a notice it's a string.

10
00:00:31,750 --> 00:00:39,520
If I say a plus one two three I get an error because A is a string and one two three is an integer and

11
00:00:39,520 --> 00:00:45,410
they can't be added together but I could say a plus string.

12
00:00:45,460 --> 00:00:46,810
One two three.

13
00:00:46,810 --> 00:00:51,950
The result is Hello One two three because A's a variable contains the string hello.

14
00:00:52,180 --> 00:00:57,820
And I've converted one two three to a string and then concatenated them together.
