1
00:00:00,220 --> 00:00:04,290
And welcome back to another class of course about Python.

2
00:00:05,790 --> 00:00:13,490
So in today's class our main topic would be for loops and you will see it's not that hard to understand.

3
00:00:13,890 --> 00:00:16,980
It's when you practice it you'll see it's gonna be very easy.

4
00:00:17,250 --> 00:00:17,810
All right.

5
00:00:17,850 --> 00:00:24,630
So basically what are Froot Loops for loops are technically a loop that is used for iterating over a

6
00:00:24,630 --> 00:00:25,100
sequence.

7
00:00:25,200 --> 00:00:30,090
So the sequence could be a dictionary could be a list could be a string could be numbers could be a

8
00:00:30,090 --> 00:00:35,060
set of numbers could be trouble could be all of those together.

9
00:00:35,100 --> 00:00:42,540
So basically what it does it will execute the set this statement sorry and the ones for each item in

10
00:00:42,540 --> 00:00:44,270
the list topple.

11
00:00:45,780 --> 00:00:49,050
It could be numbers it could be dictionaries or whatever.

12
00:00:49,500 --> 00:00:52,410
So what what does this all mean.

13
00:00:52,410 --> 00:00:57,150
Very simple let's say for example you have a list of I don't know of things.

14
00:00:57,150 --> 00:01:03,360
Well if when you're going to make your for loop when you for example you will use the for loop what's

15
00:01:03,350 --> 00:01:07,120
going to happen is that that each element will be printed.

16
00:01:07,210 --> 00:01:09,160
So let's have an example here.

17
00:01:09,160 --> 00:01:10,690
Let's use for example.

18
00:01:10,690 --> 00:01:12,630
I don't know colors.

19
00:01:12,640 --> 00:01:18,850
So in this case we will have a variable that is will a list that will be named colors.

20
00:01:18,910 --> 00:01:21,800
And in this case we will create our list.

21
00:01:21,820 --> 00:01:26,840
So let's say we'll have blue red

22
00:01:41,400 --> 00:01:41,970
orange

23
00:01:45,150 --> 00:01:46,880
and black.

24
00:01:46,950 --> 00:01:47,540
All right.

25
00:01:47,670 --> 00:01:51,000
So we have a list of far forth colors right now.

26
00:01:51,000 --> 00:01:53,710
And let's say you want to use our for loop.

27
00:01:53,910 --> 00:01:56,380
So how exactly this for loop works.

28
00:01:56,580 --> 00:01:57,890
So very simple.

29
00:01:57,900 --> 00:01:59,450
Write down for.

30
00:01:59,470 --> 00:02:08,500
So this will be our for loop then let's say for example for one color this case since we're talking

31
00:02:08,500 --> 00:02:12,650
about colors we'll say for one color in

32
00:02:15,280 --> 00:02:15,980
colors.

33
00:02:16,120 --> 00:02:20,010
In this case colors is the name of our list

34
00:02:24,820 --> 00:02:25,810
two points.

35
00:02:25,820 --> 00:02:31,380
Print one color.

36
00:02:31,750 --> 00:02:32,050
Great.

37
00:02:32,860 --> 00:02:38,780
So if we run up as you can see your eyes each color will be printed.

38
00:02:39,280 --> 00:02:45,910
This thing right here which is one colors can be changed so it could be just X and if I run the app

39
00:02:46,210 --> 00:02:50,440
as you can see it will still work.

40
00:02:51,420 --> 00:02:53,340
So it's very very simple to use again.

41
00:02:53,350 --> 00:02:56,730
So basically what exactly does loops.

42
00:02:56,730 --> 00:02:58,650
What exactly does.

43
00:02:59,070 --> 00:03:05,920
It simply prints every element let's say off a list of a string of a number of absolutely well anything.

44
00:03:05,940 --> 00:03:10,940
So let's try it just on a string to show you guys what exactly it is.

45
00:03:10,940 --> 00:03:14,550
So let's say for example we have hour another time a color.

46
00:03:14,580 --> 00:03:23,930
So let's say this time will say for letter since we are going to print the letters in.

47
00:03:24,040 --> 00:03:25,880
In this case let's say the word blue

48
00:03:28,860 --> 00:03:29,900
two points.

49
00:03:30,210 --> 00:03:37,920
Print letter because we are printing letters once again could be just X and it will work.

50
00:03:38,490 --> 00:03:42,150
So when we run our up as you can see blue is printed this way.

51
00:03:42,150 --> 00:03:45,950
So we ask Python to print each letter of the string.

52
00:03:45,940 --> 00:03:47,580
So in this case we have a string.

53
00:03:47,910 --> 00:03:52,480
So we ask Python to print every letter of this string.

54
00:03:52,590 --> 00:03:53,220
All right.

55
00:03:53,230 --> 00:04:01,670
And there are a thing in which you can use the for loop while the loop statement will be for example

56
00:04:01,670 --> 00:04:03,170
with the British statement.

57
00:04:03,170 --> 00:04:05,860
So in this case how we can run all this.

58
00:04:05,870 --> 00:04:06,880
Well it's very simple.

59
00:04:06,980 --> 00:04:09,800
Let's say for example we once again have a set of colors.

60
00:04:09,830 --> 00:04:13,400
So let's name it color colors.

61
00:04:13,700 --> 00:04:17,960
In this case we write on equal and we will put our colors here.

62
00:04:17,990 --> 00:04:21,110
So let's say we have black and

63
00:04:26,560 --> 00:04:27,970
yeah.

64
00:04:31,310 --> 00:04:31,700
And

65
00:04:34,880 --> 00:04:35,410
green.

66
00:04:38,050 --> 00:04:40,850
And finally the last one would be red.

67
00:04:41,140 --> 00:04:41,340
All right.

68
00:04:41,350 --> 00:04:50,470
We have our four colors and right now what we can use also let's say we want to stub the eighth iteration

69
00:04:50,800 --> 00:04:51,240
at Green.

70
00:04:51,280 --> 00:04:55,960
So everything will stop at the green so will only generate black yellow and green.

71
00:04:55,960 --> 00:04:57,640
In this case so very simple.

72
00:04:57,760 --> 00:05:00,540
The way it's gonna be written down.

73
00:05:00,550 --> 00:05:02,830
We will use our for loop of course.

74
00:05:02,830 --> 00:05:07,090
So for example in this case it's colors.

75
00:05:07,330 --> 00:05:08,530
So let's name it.

76
00:05:08,650 --> 00:05:12,050
Let's say for one color.

77
00:05:12,850 --> 00:05:19,300
But it could be just X or Y or any letter in colors.

78
00:05:19,300 --> 00:05:21,280
So in this list right here

79
00:05:24,390 --> 00:05:27,930
print one color

80
00:05:33,450 --> 00:05:33,730
all right.

81
00:05:34,090 --> 00:05:34,560
So what.

82
00:05:34,690 --> 00:05:37,290
All those were what all this means.

83
00:05:37,330 --> 00:05:39,790
So very simple for one color.

84
00:05:40,030 --> 00:05:45,990
So only one color in colors in this list print one color.

85
00:05:46,000 --> 00:05:46,800
So what's gonna happen.

86
00:05:46,900 --> 00:05:50,190
It's gonna print each color one after the other.

87
00:05:50,230 --> 00:05:53,960
So if we run this up as so you have black yellow green the red.

88
00:05:54,070 --> 00:06:01,600
But if we want to stop our iteration at Green for example it's very simple we can use an if statement

89
00:06:02,140 --> 00:06:09,600
and simply write down one color if one color is equal to.

90
00:06:09,670 --> 00:06:17,740
In this case green we want the loop to stop.

91
00:06:17,950 --> 00:06:20,280
So a simple two points and write down brick.

92
00:06:20,290 --> 00:06:25,660
So in this case we'll use the break statement and if we run our app as you can see we'll have black

93
00:06:25,720 --> 00:06:26,800
yellow and green.

94
00:06:26,910 --> 00:06:29,300
Everything is going to stop at Green.

95
00:06:29,330 --> 00:06:38,030
So once again this is just by using the well the how you call it the if statement of the bridge statement

96
00:06:38,040 --> 00:06:38,300
sorry.

97
00:06:38,570 --> 00:06:41,300
So if you use the brake statement it's going to all stop again.

98
00:06:41,380 --> 00:06:42,620
Let's again see the loop.

99
00:06:42,680 --> 00:06:48,380
Well the for loop is something that is not hard the very very hard to understand and it's something

100
00:06:48,380 --> 00:06:49,620
that is very simple.

101
00:06:49,730 --> 00:06:57,900
The main goal of the for loop is simply to print everything that can be in a list in a in a string in

102
00:06:57,900 --> 00:06:58,710
numbers.

103
00:06:58,740 --> 00:07:00,510
Well absolutely anywhere.

104
00:07:00,540 --> 00:07:04,730
So let's have another example.

105
00:07:04,740 --> 00:07:07,530
So in this case we'll use another.

106
00:07:07,540 --> 00:07:12,210
Well we'll talk about another statement which is the range statement.

107
00:07:12,210 --> 00:07:16,920
And in this case let's say we have four.

108
00:07:16,920 --> 00:07:21,340
Let's use let's let's call it number four.

109
00:07:21,350 --> 00:07:27,610
Number in range six

110
00:07:30,410 --> 00:07:33,160
print number.

111
00:07:33,150 --> 00:07:40,620
All right if we run this up as you can see it's gonna print all the numbers from 0 to 6 but it's not

112
00:07:40,620 --> 00:07:42,030
going to print the number 6.

113
00:07:42,240 --> 00:07:47,550
And if for example we want to print just numbers that are in let's say from one number to another.

114
00:07:47,550 --> 00:07:51,130
So in this case let's say want to print out the numbers between them.

115
00:07:51,150 --> 00:07:57,570
I don't know it could be 20 and 30 for example you can just write it this way.

116
00:07:58,050 --> 00:08:03,150
And from our app as you can see it's going to put on all the numbers that are between 20 and 30 but

117
00:08:03,150 --> 00:08:06,300
just not the 30 that you can see.

118
00:08:06,300 --> 00:08:08,710
It's not something that is very very hard to understand.

119
00:08:08,820 --> 00:08:11,810
And those are simply the basics of the for loop.

120
00:08:11,880 --> 00:08:16,010
So the way that you can use it can be way more complex.

121
00:08:16,010 --> 00:08:20,760
But in this case this is just this simple the simple part of the fault.

122
00:08:20,980 --> 00:08:26,850
So as you can see guys as I explained to the for loop the main reason why the for loop exists is really

123
00:08:26,850 --> 00:08:31,950
to help you print all the elements of let's say you could be at least it could be a dictionary.

124
00:08:31,950 --> 00:08:34,770
It could be a string could be numbers in range of numbers.

125
00:08:34,770 --> 00:08:37,860
It could be well absolutely anything.

126
00:08:37,860 --> 00:08:39,620
So right now you understand how it works.

127
00:08:39,660 --> 00:08:41,170
So that's it for this class guys.

128
00:08:41,190 --> 00:08:43,050
And see you all in our next class.
