1
00:00:03,240 --> 00:00:05,490
In this example I've gotten a boon to computer.

2
00:00:05,490 --> 00:00:07,620
I'm going to start Python 3.

3
00:00:07,800 --> 00:00:16,310
I'm going to create a variable a and set it to one two three credit variable B and set it to Hello notice

4
00:00:16,310 --> 00:00:24,860
what happens when I try and add a and b I get an error because we've got unsupported types integer and

5
00:00:24,860 --> 00:00:28,030
string a is a integer.

6
00:00:28,040 --> 00:00:37,070
We can see that by using type B is a string you can't add them together like that but I could change

7
00:00:37,220 --> 00:00:44,900
a two string and then concatenate it with B and I end up getting one two three Hello A's a variable

8
00:00:45,030 --> 00:00:53,840
B's a variable I've changed the type of a to a String b is a string I can concatenate them together

9
00:00:54,350 --> 00:01:04,280
I could as an example say B plus space plus a and I should say string a to make it a string I notice

10
00:01:04,280 --> 00:01:05,450
now I get Hello.

11
00:01:05,450 --> 00:01:06,540
One two three.

12
00:01:06,710 --> 00:01:10,470
You can't add integers and strings together Hello plus Hello.

13
00:01:10,490 --> 00:01:20,180
Doesn't give you two Hello How would you use additions for hello and by these strings they would be

14
00:01:20,180 --> 00:01:21,530
concatenated together.
