00:00:00,650 --> 00:00:06,020
Hey long time no see it's it's been a while but I'm glad you're back and I'm I'm glad you're still hanging

2
00:00:06,020 --> 00:00:06,700
in there.

3
00:00:06,800 --> 00:00:11,720
Trust me thinks things are going to get a lot more fun once we actually start building applications.

4
00:00:11,720 --> 00:00:15,710
But we do have to go through the basics so hang in there.

5
00:00:15,710 --> 00:00:23,060
Now you may have heard me mention methods and functions before and I briefly touched on the subject

6
00:00:23,090 --> 00:00:23,760
right.

7
00:00:23,810 --> 00:00:32,980
We have functions like list print we have things like Max man what else do we have.

8
00:00:32,990 --> 00:00:34,370
We have input.

9
00:00:34,370 --> 00:00:38,290
These are all built in functions in Python.

10
00:00:38,360 --> 00:00:40,800
Python just comes with this and we're able to use them.

11
00:00:41,330 --> 00:00:48,380
And we also learned about functions that we can create ourselves custom functions like well some random

12
00:00:49,610 --> 00:00:57,970
stuff and I just created a function that does absolutely nothing I can just pass through and these are

13
00:00:57,970 --> 00:01:06,640
all functions because the way we call them is Well we say some random stuff and then we call it with

14
00:01:06,640 --> 00:01:14,950
the brackets and give it some sort of data or leave it empty but we also learned about methods and methods

15
00:01:14,950 --> 00:01:22,170
were different because the way we used them was using the dot notation we said Dot something.

16
00:01:22,180 --> 00:01:32,580
For example if we had a string hello and I do dot I get a list of all these methods that the string

17
00:01:32,730 --> 00:01:34,880
data type can use.

18
00:01:35,010 --> 00:01:42,450
These aren't things that we can use like this because if I do capitalize

19
00:01:45,170 --> 00:01:49,370
like this well it's going to give me an error.

20
00:01:49,460 --> 00:01:55,920
It's going to say well I'm going to get an error with Max because it's expecting an argument here bullets

21
00:01:56,220 --> 00:02:04,910
comet this out and click Run Again I get named capitalized is not defined because it's not a function

22
00:02:05,360 --> 00:02:13,460
it's a method and then method has to be owned by something and who owns a method well whatever is to

23
00:02:13,460 --> 00:02:25,590
the left of the dot in our case the string owns the method capitalized and that's what methods are they're

24
00:02:25,940 --> 00:02:35,100
built in objects that have methods such as strings dictionaries sets topples all the things we've talked

25
00:02:35,100 --> 00:02:43,980
about where as soon as we do dot we have access to all these methods they're owned by an object or a

26
00:02:43,980 --> 00:02:44,510
data type.

27
00:02:45,150 --> 00:02:52,560
And the fun thing is that there's a ways to build your own methods and I'll show you how to do that

28
00:02:52,560 --> 00:02:58,680
later on and when we start talking about classes but he can see here that our editors help us determine

29
00:02:58,890 --> 00:03:01,040
what type of methods that we can use.

30
00:03:01,140 --> 00:03:09,600
And again these are built into python and you can also learn about these methods that we can use by

31
00:03:09,600 --> 00:03:11,610
going to the Python documentation right.

32
00:03:11,610 --> 00:03:19,860
Python 3 documentation is going to have a ton of things for us if we go to library reference for example

33
00:03:20,160 --> 00:03:22,770
we can see here that we can learn about built in types.

34
00:03:22,770 --> 00:03:26,260
So let's go to let's go to the set types.

35
00:03:26,490 --> 00:03:29,840
And here you can see that we have set type.

36
00:03:29,970 --> 00:03:31,470
And it shows us how we can use it.

37
00:03:31,680 --> 00:03:37,200
Now Python doesn't have the easiest documentation to read for beginners unfortunately.

38
00:03:37,320 --> 00:03:44,640
So sometimes it's better to actually just Google instead of going through the actual documentation but

39
00:03:44,640 --> 00:03:53,260
you see here that the set type has clear has pop has remove if we want to use it we have update.

40
00:03:53,400 --> 00:04:01,710
And these are the methods that we can use but at the end of the day both methods and functions allow

41
00:04:01,710 --> 00:04:09,780
us to take actions right to take actions on our data types to have our programs do something.

42
00:04:09,780 --> 00:04:15,150
And although they have these different names and one has a dot in front of it and another one while

43
00:04:15,150 --> 00:04:17,310
we can just call it like this.

44
00:04:17,310 --> 00:04:19,380
The difference is very minimal.

45
00:04:19,410 --> 00:04:24,580
But keep that in mind when you hear people talking about methods and functions there is that difference.

46
00:04:24,600 --> 00:04:29,610
And like I said before we will get two methods when we talk about classes to show you how we can create

47
00:04:29,910 --> 00:04:30,760
our own.

48
00:04:30,960 --> 00:04:32,170
I'll see in the next one.

49
00:04:32,330 --> 00:04:32,550
Bob.
