00:00:00,690 --> 00:00:01,890
Instructor: Welcome back.

2
00:00:01,890 --> 00:00:04,200
I want to quickly touch on the subject

3
00:00:04,200 --> 00:00:07,893
of what we call string concatenation.

4
00:00:08,850 --> 00:00:11,970
Yes, programmers love creating really

5
00:00:11,970 --> 00:00:16,970
complex names when concepts may not be as complex.

6
00:00:17,040 --> 00:00:20,400
So what does string concatenation mean?

7
00:00:20,400 --> 00:00:23,850
Well, it simply means adding strings together.

8
00:00:23,850 --> 00:00:27,623
So I can do hello plus Andrei

9
00:00:29,520 --> 00:00:31,500
and I've concatenated this string.

10
00:00:31,500 --> 00:00:34,230
I've added two strings together.

11
00:00:34,230 --> 00:00:38,913
So if I print this, I get hello Andrei.

12
00:00:39,810 --> 00:00:41,400
So if you ever hear people talk

13
00:00:41,400 --> 00:00:44,520
about string concatenation, that's what they mean.

14
00:00:44,520 --> 00:00:47,700
We're concatenating strings.

15
00:00:47,700 --> 00:00:49,260
By the way, what do you think will happen

16
00:00:49,260 --> 00:00:54,123
if I do hello plus five?

17
00:00:55,410 --> 00:00:57,240
If I click run,

18
00:00:57,240 --> 00:01:00,423
hmm, that's not good, is it?

19
00:01:01,500 --> 00:01:03,420
I get TypeError.

20
00:01:03,420 --> 00:01:05,673
Must be string not int.

21
00:01:06,810 --> 00:01:09,750
So it looks like string concatenation

22
00:01:09,750 --> 00:01:12,063
only works with strings.

23
00:01:13,200 --> 00:01:15,950
We'll explore that a little bit more in the next video.
