1
00:00:00,360 --> 00:00:01,020
Or not.

2
00:00:01,050 --> 00:00:02,880
It is time to start with the numbers.

3
00:00:02,960 --> 00:00:06,900
OK, so again, this is the president's big problem.

4
00:00:07,230 --> 00:00:09,900
So inside it, let's print what?

5
00:00:10,080 --> 00:00:12,210
OK, like, it's as simple as that.

6
00:00:12,330 --> 00:00:16,770
Now, let's open the terminal here and it's just up the road.

7
00:00:17,100 --> 00:00:17,920
And Bressington.

8
00:00:17,980 --> 00:00:23,370
OK, D'Abruzzo, which is the last command, as you can see, by the way, I'm sure you are familiar

9
00:00:23,370 --> 00:00:26,990
with that, but I'm just giving you some hints in case you don't know.

10
00:00:27,030 --> 00:00:32,610
OK, so the center, which is the last command, which is the button three first by and you can see

11
00:00:32,610 --> 00:00:35,670
that it is one because we print that one number.

12
00:00:35,760 --> 00:00:44,370
OK, now what if I typed that operation plus or the additional operation like this now and if I typed

13
00:00:44,910 --> 00:00:52,790
for example and I copy and paste that the same thing for multiplication, for addition.

14
00:00:52,800 --> 00:00:53,700
Sorry about that.

15
00:00:54,000 --> 00:00:57,820
Subtraction, multiplication and division, by the way.

16
00:00:58,110 --> 00:01:00,570
So but let's change the values.

17
00:01:00,570 --> 00:01:03,900
So he only put ten minus one.

18
00:01:03,930 --> 00:01:09,170
And here let's put two multiplied by four or by three.

19
00:01:09,180 --> 00:01:11,040
Anyway, here let's put.

20
00:01:12,050 --> 00:01:16,670
Ten multiplied by five and so on, just about everybody.

21
00:01:16,820 --> 00:01:19,430
OK, now here, if I return to that.

22
00:01:21,060 --> 00:01:28,590
And let's put that, you can see that it is two nine six two point five and so on, OK, which is two,

23
00:01:28,740 --> 00:01:34,890
by the way, this is integer multiplied by an integer, but it will give you that as a float value.

24
00:01:35,070 --> 00:01:36,710
OK, which is 2.0.

25
00:01:36,760 --> 00:01:38,970
OK, because this is the division now.

26
00:01:39,780 --> 00:01:47,050
We have this function called the type and inside it, let's put that value.

27
00:01:47,940 --> 00:01:49,640
This will return to the value.

28
00:01:50,070 --> 00:01:52,500
What will that that return.

29
00:01:52,710 --> 00:02:01,860
OK, so if I type type type 10 multiplied by five now this should return float and the same thing for

30
00:02:01,860 --> 00:02:02,630
the one plus one.

31
00:02:02,640 --> 00:02:07,360
I don't need to put them for everything just to do that and test it out.

32
00:02:07,380 --> 00:02:07,750
OK.

33
00:02:08,070 --> 00:02:08,880
So yeah.

34
00:02:10,220 --> 00:02:16,510
If you can see that the glass is for the first one, which is the one plus one.

35
00:02:16,530 --> 00:02:19,170
OK, now 14 divided by five.

36
00:02:19,680 --> 00:02:23,710
You can see that it is a float, which is the two point zero.

37
00:02:24,120 --> 00:02:32,940
So as you can see, by using this function, we learned how to know what is the data type for this specific

38
00:02:32,940 --> 00:02:33,310
number.

39
00:02:33,360 --> 00:02:33,730
OK.

40
00:02:34,020 --> 00:02:36,670
Now, actually, there are other things, which is the explanation.

41
00:02:36,960 --> 00:02:48,220
So if I type print like this and to the explanation is double start, OK, or there are six to three.

42
00:02:48,450 --> 00:02:49,650
So this will give us.

43
00:02:51,080 --> 00:02:51,560
Eight.

44
00:02:53,520 --> 00:02:54,750
So if I return here.

45
00:02:56,440 --> 00:02:57,160
To determine that.

46
00:02:57,950 --> 00:03:03,740
And Bouttier, yeah, it is eight, but let's clear the screen, actually, yeah, it is eight, as

47
00:03:03,740 --> 00:03:04,690
you can see now.

48
00:03:04,700 --> 00:03:09,620
And we have the module which is there, if you can see it.

49
00:03:09,620 --> 00:03:10,490
Is that two?

50
00:03:11,440 --> 00:03:13,510
In the forward slash.

51
00:03:15,070 --> 00:03:21,890
So if I type to and here is for OK, so this should return zero.

52
00:03:22,780 --> 00:03:27,280
So, yeah, as you can see, it is, you know, don't worry about the map.

53
00:03:27,280 --> 00:03:34,870
Actually, this is not about math, but I'm just giving you a brief overview how to use both in that.

54
00:03:35,050 --> 00:03:41,020
OK, now the next lecture, we will start learning some of that math functions actually that can be

55
00:03:41,020 --> 00:03:45,610
used like the absolute, like the cosine sine whatever.

56
00:03:45,670 --> 00:03:50,230
OK, but again, this is not about math or something like this.

57
00:03:50,710 --> 00:03:54,970
This is about ethical hacking and about creating the only thing and using Python.

58
00:03:54,970 --> 00:03:59,020
But to do that, you need to understand the python first.

59
00:03:59,050 --> 00:04:00,280
OK, all right.

60
00:04:00,280 --> 00:04:00,940
I will see you there.
