00:00:07,920 --> 00:00:08,940
Hi everybody.

2
00:00:08,940 --> 00:00:10,840
Welcome back.

3
00:00:10,860 --> 00:00:17,220
In this video we will discuss Object Oriented Programming.

4
00:00:17,770 --> 00:00:28,200
Magical Dunder missiles Dunder missives no missiles is used with constructor which is any missile.

5
00:00:28,500 --> 00:00:37,920
Example underscore underscore Len underscore vanities as global entities and underscore David underscore

6
00:00:37,990 --> 00:00:43,560
his third voters rank double underscore

7
00:00:46,320 --> 00:00:47,740
member entities cross-border entities.

8
00:00:47,830 --> 00:00:57,670
We use these missiles for specific functions like if we want to brand an object we can do that by using

9
00:00:57,810 --> 00:00:59,620
an IT missile alone.

10
00:00:59,620 --> 00:01:06,280
But we use double underscore to string double underscore or memory entities close parentheses missile

11
00:01:06,640 --> 00:01:07,030
alone

12
00:01:10,760 --> 00:01:19,880
and if we want to calculate the lens of an object we use double underscore and E N double underscore

13
00:01:20,160 --> 00:01:28,250
embedded to the schools and entities missile let's try that in the end it method from the last value

14
00:01:29,280 --> 00:01:32,170
we have glass that I use it.

15
00:01:32,670 --> 00:01:42,720
Yes and it self name and age self the name equal one name fiftieth age equal age user underscore one

16
00:01:42,840 --> 00:01:52,300
equals that the user was tougher and sixteen user underscored two that the user timer and 36.

17
00:01:52,620 --> 00:01:54,210
We have this glass.

18
00:01:54,350 --> 00:01:59,390
Let's bring User 1 Brent

19
00:02:02,100 --> 00:02:04,280
User 1.

20
00:02:04,680 --> 00:02:13,360
We will get that object in the memory of our glass mean that the user is a memory of our class that

21
00:02:13,440 --> 00:02:22,480
uses plan of our user one.

22
00:02:23,020 --> 00:02:24,870
We will get type error.

23
00:02:25,060 --> 00:02:32,130
Our object of type that the user has no lens what we can do to me to bring to our user and measures

24
00:02:32,140 --> 00:02:46,050
the lens we will use magical dander methods and with the constructor let's go and do that let's put

25
00:02:46,230 --> 00:02:49,290
our magic string of missile he he's

26
00:02:53,540 --> 00:02:59,670
year double underscored string self

27
00:03:03,050 --> 00:03:06,320
grows by entities call them enter return

28
00:03:13,170 --> 00:03:14,040
then if

29
00:03:20,190 --> 00:03:20,730
user

30
00:03:25,760 --> 00:03:26,210
name

31
00:03:29,430 --> 00:03:29,820
is

32
00:03:34,380 --> 00:03:37,460
get record growth and records.

33
00:03:41,610 --> 00:03:42,530
And the has

34
00:03:47,740 --> 00:03:52,060
to get it back in because we've got a record year.

35
00:03:59,050 --> 00:03:59,750
That's for me.

36
00:04:04,220 --> 00:04:06,470
That's the name for the main

37
00:04:09,320 --> 00:04:10,680
cell.

38
00:04:11,120 --> 00:04:13,900
The AIDS benefit of AIDS.

39
00:04:17,380 --> 00:04:19,820
Yes.

40
00:04:19,970 --> 00:04:28,330
Level underscore in the end double underscore.

41
00:04:29,260 --> 00:04:29,550
Cell

42
00:04:34,250 --> 00:04:34,870
return

43
00:04:37,450 --> 00:04:40,240
cell that hits

44
00:04:43,520 --> 00:04:50,420
tiff and then then we will bring user one

45
00:04:58,290 --> 00:05:02,880
it will be granted so easy.

46
00:05:02,880 --> 00:05:03,920
No problem.

47
00:05:04,230 --> 00:05:06,570
We will calculate the length of user 1

48
00:05:13,020 --> 00:05:15,850
we will get 16.

49
00:05:16,080 --> 00:05:22,590
Also we will do that for user to rent user to

50
00:05:26,030 --> 00:05:36,360
brain to use that to shift and enter user name is tamer and has seventy six years old and lengths of

51
00:05:36,360 --> 00:05:37,110
user to

52
00:05:41,710 --> 00:05:43,320
36.

53
00:05:43,330 --> 00:05:44,560
Thank you for watching.

54
00:05:44,560 --> 00:05:46,180
See you next lecture.
