00:00:00,150 --> 00:00:03,850
Hello, guys, and welcome back to the lower class of our course about the complete introduction to

2
00:00:03,850 --> 00:00:06,310
the science with the use of Python.

3
00:00:06,930 --> 00:00:13,200
So in this class, we are still going to talk about SkyBitz and how all this works, but basically how

4
00:00:13,200 --> 00:00:13,620
it works.

5
00:00:13,630 --> 00:00:17,920
Skyfire, which is another tool inside of Python.

6
00:00:17,960 --> 00:00:19,420
So basically Python Library.

7
00:00:20,610 --> 00:00:22,350
So what we'll do today is pretty simple.

8
00:00:22,350 --> 00:00:28,470
We are going to work with Skype as well as Numberi, and we are going to work with another package of

9
00:00:28,470 --> 00:00:30,250
Skype, which is called for you.

10
00:00:30,780 --> 00:00:34,390
So we are going to make a full transformation for you.

11
00:00:34,850 --> 00:00:37,650
So basically for those who don't know what is it for you?

12
00:00:37,650 --> 00:00:43,980
Analysis is a method for expressing a function as a sum of periodic components and for recovering the

13
00:00:43,980 --> 00:00:45,660
signals from those components.

14
00:00:45,720 --> 00:00:48,960
This is simply the main terminology of it.

15
00:00:49,830 --> 00:00:55,770
So basically it provides a way to replace a number of functions and Skype with its own functions, which

16
00:00:55,770 --> 00:01:00,960
are usually significantly faster via by 50.

17
00:01:01,350 --> 00:01:04,080
So basically with this package interface.

18
00:01:05,190 --> 00:01:05,600
All right.

19
00:01:06,000 --> 00:01:08,580
So basically how all this would work is pretty simple.

20
00:01:09,020 --> 00:01:16,320
We are going to use the 50 sub package to be able to perform this transformation and to be able to perform

21
00:01:16,320 --> 00:01:17,520
this transformation as well.

22
00:01:17,550 --> 00:01:19,900
We are going to require an.

23
00:01:20,340 --> 00:01:24,330
So basically we are going to work with an array number.

24
00:01:24,420 --> 00:01:28,020
So we will need to import Skype as well as numbers.

25
00:01:28,050 --> 00:01:33,510
So basically, before we even start this, you guys need to check in your settings if you have important

26
00:01:33,510 --> 00:01:37,740
numbers and if you have Skype, usually normally you should have both of them.

27
00:01:38,670 --> 00:01:39,050
All right.

28
00:01:39,960 --> 00:01:43,660
So first thing that will do, import Skype, as we always do.

29
00:01:43,680 --> 00:01:52,850
So just import what exactly will the import import Skype as spe then what exactly we need to import,

30
00:01:53,430 --> 00:02:01,350
we need to import the library so we'll just import numpty as well as ENPI.

31
00:02:02,540 --> 00:02:07,100
So right now, we have imported the two libraries that we need and next thing that we need, we need

32
00:02:07,100 --> 00:02:10,010
to import the sub package that is inside of SCoPI.

33
00:02:10,030 --> 00:02:17,490
So in this case, what some package will need will need 50 sub package to be able to run this transformation.

34
00:02:18,170 --> 00:02:19,180
So pretty simple.

35
00:02:19,190 --> 00:02:20,530
We will just write it down.

36
00:02:20,540 --> 00:02:27,240
So from Skype, we want to import the 50 sub package.

37
00:02:27,260 --> 00:02:35,900
So right now we have imported 50 some package from Skype and we will be able to use it from this moment.

38
00:02:35,900 --> 00:02:38,850
When I do right now, we want to create our first area.

39
00:02:38,890 --> 00:02:43,970
So basically we will create a two dimensional aristo for those who don't remember how to create an array.

40
00:02:44,000 --> 00:02:46,370
It's pretty simple what we need.

41
00:02:46,370 --> 00:02:49,530
At first, we need to create a variable where we will store our area.

42
00:02:49,550 --> 00:02:55,340
So the name of their variable will be the one, as always, and we'll create our area.

43
00:02:55,370 --> 00:02:57,320
So basically we will start with ENPI.

44
00:02:57,320 --> 00:03:02,270
So we are making a reference to number by fire and DOT.

45
00:03:02,390 --> 00:03:08,690
And then since we are making this reference to company, we want to write down the function that will

46
00:03:08,690 --> 00:03:09,470
use in this case.

47
00:03:09,470 --> 00:03:17,150
We'll use the functionality, we open up the parenthesis and we can write down are.

48
00:03:17,450 --> 00:03:19,330
So basically we will do as we always do.

49
00:03:19,340 --> 00:03:21,820
So even and odd numbers are two, four, six.

50
00:03:21,920 --> 00:03:23,260
This is what I usually do.

51
00:03:23,930 --> 00:03:27,860
If you guys want to write down other numbers, it's up to you.

52
00:03:28,850 --> 00:03:30,830
So one, three, five.

53
00:03:31,010 --> 00:03:33,280
So basically we have a two dimensional, as you can see.

54
00:03:34,430 --> 00:03:39,620
All right, so what we'll do right now, usually to be sure that everything works fine, I like to print

55
00:03:39,620 --> 00:03:43,100
my area, so we'll print it and look what it looks like.

56
00:03:43,130 --> 00:03:48,410
So basically, if we don't make a mistake or if there is no problem and if there is a problem, we can

57
00:03:48,410 --> 00:03:48,800
correct it.

58
00:03:48,800 --> 00:03:50,170
So you can see there is a problem here.

59
00:03:50,510 --> 00:03:54,470
I wrote dots instead of commas, so I'll correct it.

60
00:03:56,180 --> 00:03:58,580
So what we'll do right now, we'll just rerun the app.

61
00:03:59,540 --> 00:04:01,820
And as you can see right now, it works pretty fine.

62
00:04:01,830 --> 00:04:02,900
So that's amazing.

63
00:04:03,440 --> 00:04:03,770
All right.

64
00:04:03,780 --> 00:04:09,680
So right now we have our first variable, which is our iris or iris inside of our variables.

65
00:04:09,980 --> 00:04:11,140
What to do right now?

66
00:04:11,150 --> 00:04:17,750
We want to create a second variable which will be used to make the transformation, let's call it in

67
00:04:17,750 --> 00:04:20,090
this case, trends one.

68
00:04:20,130 --> 00:04:21,800
So this will be transformation one.

69
00:04:23,120 --> 00:04:25,850
So instead of transforming, what we'll do will use the function.

70
00:04:25,850 --> 00:04:29,720
FFE so pretty simple how exactly we use it.

71
00:04:30,080 --> 00:04:33,830
We want to use a Skype function.

72
00:04:33,830 --> 00:04:37,460
So spe function that is in this package.

73
00:04:37,460 --> 00:04:40,990
FFE so ffe basically Ifti.

74
00:04:41,450 --> 00:04:41,840
All right.

75
00:04:41,850 --> 00:04:45,050
So from this moment what we'll do right now is pretty simple.

76
00:04:45,590 --> 00:04:52,820
We want to make this transformation to our variable veigar one, which is just there.

77
00:04:52,820 --> 00:04:55,560
So you can see our vair one is right here.

78
00:04:56,450 --> 00:04:59,680
So from this moment we want to print right now, we want to print trends.

79
00:04:59,750 --> 00:05:05,150
One, since we we made a transformation to the air one.

80
00:05:05,150 --> 00:05:06,710
So we have our area right here.

81
00:05:07,100 --> 00:05:08,870
Here in this line of code.

82
00:05:08,870 --> 00:05:13,120
We are making our transformation via this operation right here.

83
00:05:13,130 --> 00:05:19,580
So we are applying this operation right here to this function right here, to this label right here.

84
00:05:20,240 --> 00:05:23,150
So we want to do right now, we simply want to run everything.

85
00:05:23,510 --> 00:05:27,890
And as you can see, the transformation have been made work.

86
00:05:27,910 --> 00:05:29,050
So it works pretty fine.

87
00:05:29,480 --> 00:05:32,750
So this would be the end of the operation.

88
00:05:32,990 --> 00:05:33,800
So let's get to see you guys.

89
00:05:33,800 --> 00:05:38,360
This is exactly how we can do a four year transformation way for your analysis.

90
00:05:38,360 --> 00:05:40,880
So you can see it's pretty simple to do.

91
00:05:41,780 --> 00:05:42,170
All right.

92
00:05:42,440 --> 00:05:44,540
So I hope you guys understood everything.

93
00:05:44,540 --> 00:05:45,770
It's not that complicated.

94
00:05:45,770 --> 00:05:50,960
And I hope you guys saw that you can use non-pay as well as Skype together.

95
00:05:51,320 --> 00:05:52,460
So that's it for us guys, guys.

96
00:05:52,460 --> 00:05:54,560
And see you all in our next class.
