00:00:00,000 --> 00:00:03,540
Hi, welcome to a new video. This is an

2
00:00:03,541 --> 00:00:06,060
introductory video of the functions and

3
00:00:06,061 --> 00:00:09,540
conditionals section. So now you're entering a

4
00:00:09,541 --> 00:00:14,280
more advanced section of Python. Functions and

5
00:00:14,281 --> 00:00:17,250
conditionals are some advanced core concepts of

6
00:00:17,251 --> 00:00:21,300
Python, and these are very fundamental blocks, which

7
00:00:21,301 --> 00:00:23,760
you can use to make your programs more

8
00:00:23,761 --> 00:00:26,820
intelligent, and more manageable. So you make your

9
00:00:26,821 --> 00:00:30,180
programs more intelligent by making them take

10
00:00:30,181 --> 00:00:33,570
decisions, and that you can implement a via

11
00:00:33,571 --> 00:00:37,170
conditionals. So if your program gets some inputs,

12
00:00:37,200 --> 00:00:39,990
and you want to think, you want to make your

13
00:00:39,991 --> 00:00:43,950
program think if that input is fine or not, and

14
00:00:43,951 --> 00:00:47,280
you want to do something if that input is true,

15
00:00:47,370 --> 00:00:53,370
and something else if that is input is false. So you're making decisions in your program

16
00:00:53,371 --> 00:00:55,890
through a conditional block. And then you have

17
00:00:55,891 --> 00:00:59,970
functions on the other hand. Functions are used

18
00:00:59,971 --> 00:01:04,830
to wrap in blocks of code, so similar blocks of

19
00:01:04,831 --> 00:01:08,100
codes, it helps you organize your code. So a

20
00:01:08,101 --> 00:01:14,433
function for example, could convert USD to Euros.

21
00:01:14,434 --> 00:01:17,670
So this function does this certain things

22
00:01:17,671 --> 00:01:20,970
and does it well. So it gets USD as input

23
00:01:21,000 --> 00:01:25,620
and it gives you Euros as output. So inside the

24
00:01:25,621 --> 00:01:28,590
function, you have those Math operations which do

25
00:01:28,591 --> 00:01:32,460
the conversion. So conditionals and functions are

26
00:01:32,461 --> 00:01:34,950
two things you're going to learn this section

27
00:01:35,190 --> 00:01:39,700
through examples, of course. So I'll see you in the next video.
