1
00:00:10,210 --> 00:00:10,910
Welcome.

2
00:00:10,960 --> 00:00:17,000
And this video will resolve last videos assignments, which analysts practice advanced.

3
00:00:17,300 --> 00:00:23,680
So, first of all, let's great a new file that's got collections, lists, practice

4
00:00:26,380 --> 00:00:27,190
advanced.

5
00:00:31,010 --> 00:00:38,870
All right, so let's leave a note also, collections lists practice.

6
00:00:42,310 --> 00:00:43,650
That's great.

7
00:00:44,120 --> 00:00:50,330
So first of all, I well, I asked you guys to create an employee employee's list.

8
00:00:54,560 --> 00:00:58,760
Creative employees, less so let's just declare it.

9
00:01:01,060 --> 00:01:11,400
Like this and state, the employees are here, so we have John Roberts or Adam or John.

10
00:01:11,650 --> 00:01:12,670
Yeah, like this.

11
00:01:15,910 --> 00:01:20,560
And let's not forget about the women we have, Dana and Ashley.

12
00:01:20,890 --> 00:01:21,480
Correct.

13
00:01:22,360 --> 00:01:22,750
Great.

14
00:01:22,780 --> 00:01:27,430
So, first of all, I asked you guys in the first assignment, just going to mention here the number

15
00:01:27,430 --> 00:01:28,050
of those times women.

16
00:01:28,060 --> 00:01:31,250
So we don't get mixed once we print all of them.

17
00:01:31,570 --> 00:01:37,210
So first of all, I asked you guys to print the list simply, is that so?

18
00:01:37,210 --> 00:01:43,030
Casting their employees and it's printed just to make sure.

19
00:01:43,980 --> 00:01:44,580
All right.

20
00:01:45,490 --> 00:01:45,770
All right.

21
00:01:45,820 --> 00:01:47,120
So we have the list right here.

22
00:01:47,830 --> 00:01:54,360
Then I wanted you guys to print the length of the list.

23
00:01:54,790 --> 00:01:57,940
So first of all, we have the list.

24
00:01:58,150 --> 00:02:00,970
OK, so anybody remember the key word?

25
00:02:01,190 --> 00:02:02,730
You print out the length of the list.

26
00:02:02,740 --> 00:02:05,110
We went over this in previous practice videos.

27
00:02:05,620 --> 00:02:09,060
So the key word, these is length.

28
00:02:10,270 --> 00:02:14,080
So this will give us the length of the list.

29
00:02:14,500 --> 00:02:23,050
So all around it, let's get the print action like this and let's also give a string and indicative

30
00:02:23,230 --> 00:02:24,570
string example.

31
00:02:24,640 --> 00:02:30,070
The length of the list is and this is assignment number two.

32
00:02:30,070 --> 00:02:30,610
Correct.

33
00:02:31,210 --> 00:02:31,930
Like this.

34
00:02:32,320 --> 00:02:35,110
And here closing quotation marks and plus.

35
00:02:35,710 --> 00:02:37,510
And I also want to show you a cool trick.

36
00:02:37,720 --> 00:02:45,010
You see that bit from having, like, weird brown background here on the lank employees.

37
00:02:45,190 --> 00:02:47,140
So I'm just going to click it once and then hover.

38
00:02:47,560 --> 00:02:54,220
And you see it states here that he has some kind of problem expects type string, but got an end.

39
00:02:55,010 --> 00:02:55,860
And why is that?

40
00:02:55,960 --> 00:03:03,550
Let's think and we have this message because lank states the length of the list and this is actually

41
00:03:03,910 --> 00:03:04,650
a string.

42
00:03:04,870 --> 00:03:11,710
But as we discussed many times, when we try to print something so by Trump does not like having two

43
00:03:11,710 --> 00:03:14,040
types of dots us inside the print.

44
00:03:14,050 --> 00:03:18,070
So we have a string and also have you anent.

45
00:03:18,340 --> 00:03:19,350
So that's not OK.

46
00:03:19,360 --> 00:03:24,190
So let's also cover it with a casting of string like this.

47
00:03:25,000 --> 00:03:27,760
And now we don't have any issues.

48
00:03:27,760 --> 00:03:33,310
We don't have the shady background behind the employees.

49
00:03:34,360 --> 00:03:35,080
Let's print it.

50
00:03:37,240 --> 00:03:37,660
Great.

51
00:03:37,660 --> 00:03:39,520
So we have the length printed out here.

52
00:03:39,910 --> 00:03:44,510
Just want to mention an important thing we already discussed, but it's worth mentioning.

53
00:03:45,100 --> 00:03:47,020
Remember this thing, guys.

54
00:03:47,890 --> 00:03:48,250
All right.

55
00:03:48,250 --> 00:03:50,290
So we have the indexes.

56
00:03:50,290 --> 00:03:50,610
All right.

57
00:03:50,650 --> 00:03:54,450
We already discussed index and why it is so index of the list.

58
00:03:54,580 --> 00:03:59,440
This one is index zero, this index one, index two and three and index four.

59
00:03:59,680 --> 00:04:07,180
So in total, the last index we have is for this is regarding indexes and in a different topic once

60
00:04:07,180 --> 00:04:08,780
we talk about the length.

61
00:04:09,250 --> 00:04:09,850
All right.

62
00:04:10,060 --> 00:04:13,060
So the length starts its count down from one.

63
00:04:13,330 --> 00:04:17,020
And that's why you see here five and not for it starts from one.

64
00:04:17,020 --> 00:04:20,450
So we have one, two, three, four and five.

65
00:04:21,340 --> 00:04:27,760
So once discussing the length, it starts from one, once discussing the index, it starts from zero.

66
00:04:27,790 --> 00:04:31,150
You have to differentiate, differentiate between the two of these.

67
00:04:32,260 --> 00:04:32,520
Great.

68
00:04:32,560 --> 00:04:35,800
So let's head over to the next assignment once.

69
00:04:36,400 --> 00:04:37,480
Jack sorry.

70
00:04:37,480 --> 00:04:44,920
John left, Jack took its place.

71
00:04:47,710 --> 00:04:57,250
So let's use the let's, first of all, declare a mansion, so that's the mentioned the list and then

72
00:04:57,520 --> 00:04:59,780
choose the index that we would like to change.

73
00:05:00,130 --> 00:05:06,790
So once applying it with square brackets, with a number of the index and then after equals, we put

74
00:05:06,790 --> 00:05:12,070
the new value, this will run over the value here and put the new value instead of it.

75
00:05:16,620 --> 00:05:25,860
Jack added, instead of John, and this one was assignment number three.

76
00:05:27,720 --> 00:05:28,510
All right.

77
00:05:28,520 --> 00:05:36,840
And here in the casting staff sorry, staff and then employees enter and I sprinted.

78
00:05:39,510 --> 00:05:45,730
OK, so we had we had John and I, we have Jack here, so this is great.

79
00:05:45,740 --> 00:05:47,210
This is exactly what we wanted.

80
00:05:48,050 --> 00:05:48,620
All right.

81
00:05:48,620 --> 00:05:50,900
So let's go over to the next assignment.

82
00:05:50,930 --> 00:05:53,090
So now we have a new employee, right?

83
00:05:56,770 --> 00:06:00,730
And the company, LAT's added.

84
00:06:03,840 --> 00:06:14,670
That's added to in the extreme, but this time we have to remember not to run over zero one, two,

85
00:06:14,670 --> 00:06:16,810
three, not to run over Dana.

86
00:06:16,830 --> 00:06:18,360
We want to add maverick.

87
00:06:18,810 --> 00:06:19,380
All right.

88
00:06:19,920 --> 00:06:23,670
New employee in the company, Maverick.

89
00:06:24,750 --> 00:06:30,320
Let's add it to industry without moving, Dana.

90
00:06:31,110 --> 00:06:34,300
So we have to be careful not to remove Dana.

91
00:06:34,410 --> 00:06:35,790
We don't want to upset her.

92
00:06:36,540 --> 00:06:37,110
All right.

93
00:06:37,110 --> 00:06:41,040
So that's the maverick and we can do it.

94
00:06:41,340 --> 00:06:42,540
You know what lot before that.

95
00:06:42,840 --> 00:06:45,690
Let's just head out to the action itself.

96
00:06:45,690 --> 00:06:48,930
So we have employee then.

97
00:06:49,260 --> 00:06:52,350
Then we have the insert key, key, key action key.

98
00:06:52,710 --> 00:06:54,870
And then we choose the.

99
00:06:55,410 --> 00:07:00,660
All right, let's put the comma first and then we choose the left, the cell that we want to answer

100
00:07:00,660 --> 00:07:03,310
to and then the value to the right.

101
00:07:03,600 --> 00:07:11,670
So what will happen is whoever is on cell number three will move over and Maverick will go instead.

102
00:07:12,120 --> 00:07:15,990
That sprint, it added Maverick.

103
00:07:19,500 --> 00:07:25,500
To sell three, and this is assignment number four.

104
00:07:28,560 --> 00:07:32,340
So SDR employee and Toura and let's run it.

105
00:07:34,360 --> 00:07:40,880
All right, so you seize this index zero, index one and X2 and index three, so on index three, we

106
00:07:40,880 --> 00:07:43,580
have Maverick and then moved over to the right.

107
00:07:43,910 --> 00:07:48,020
This is exactly what we wanted because we didn't want to remove Dana from the list.

108
00:07:48,860 --> 00:07:49,460
Great.

109
00:07:49,870 --> 00:07:57,350
OK, and that's headed over to the next assignment, which is remove Maverick

110
00:08:00,950 --> 00:08:05,660
and add him to the end of the list.

111
00:08:06,080 --> 00:08:15,110
Using a band, you don't have to use a band that you can also use the insert as well because it's the

112
00:08:15,110 --> 00:08:15,830
same thing.

113
00:08:16,280 --> 00:08:18,530
But I chose to use a band.

114
00:08:18,860 --> 00:08:23,930
So first of all, we would like to remove him completely.

115
00:08:24,770 --> 00:08:32,480
So we have employees that and then we have the action remove and let's state here that it's maverick

116
00:08:33,290 --> 00:08:36,390
and the quotation marks and then print.

117
00:08:37,340 --> 00:08:47,900
So this assignment was five a not mistaken and then remove Maverick from the list.

118
00:08:49,460 --> 00:08:50,030
All right.

119
00:08:50,100 --> 00:08:50,780
I'm sorry.

120
00:08:52,700 --> 00:08:58,970
Like this that sprint it and see that it has been removed so well.

121
00:08:58,970 --> 00:08:59,190
All right.

122
00:08:59,210 --> 00:09:00,830
So Maverick has been removed.

123
00:09:01,070 --> 00:09:06,680
By the way, guys, if you get into trouble with these assignments, just look over to the presentation

124
00:09:06,680 --> 00:09:12,890
attached to the previous lecture or just watched the previous lecture and you would see all of this

125
00:09:13,040 --> 00:09:15,950
all of these key action keys mentioned there.

126
00:09:16,430 --> 00:09:23,030
OK, so now we removed the maverick from the list and we don't see him anymore.

127
00:09:23,390 --> 00:09:30,560
And then what we wanted to do is to add Maverick to.

128
00:09:33,660 --> 00:09:38,370
Index three, same as we did before.

129
00:09:39,540 --> 00:09:45,270
All right, so employees that insert three.

130
00:09:47,860 --> 00:09:55,570
Oh, sorry, I just got a mistake here at Maverick to the end of the list, correct.

131
00:09:56,200 --> 00:09:59,910
So it's not insert, it's not a band.

132
00:10:00,390 --> 00:10:04,630
OK, and then we want to add Maverick to the end.

133
00:10:05,760 --> 00:10:06,330
All right.

134
00:10:06,340 --> 00:10:06,780
Like this.

135
00:10:06,790 --> 00:10:07,810
So a band action.

136
00:10:07,810 --> 00:10:14,840
We all went over in the previous practice video, which was the bonus assignment, and we can now see

137
00:10:14,840 --> 00:10:15,870
it here as well.

138
00:10:16,150 --> 00:10:19,930
So that's Brent Maverick first.

139
00:10:20,190 --> 00:10:26,440
First of all, I need to put to you that this is 5V and Maverick.

140
00:10:31,350 --> 00:10:33,690
Add it to the end of the list.

141
00:10:34,350 --> 00:10:44,430
OK, this SDR and employee's printed great.

142
00:10:44,430 --> 00:10:52,410
So Mattrick, first of all, he was here then he was remove the tile and then he was added to the end

143
00:10:52,410 --> 00:10:52,980
of the list.

144
00:10:53,180 --> 00:11:00,990
In what way we can use to add Maverick to the end of the list beside the fact we can also use employees

145
00:11:02,220 --> 00:11:04,710
and use the insert.

146
00:11:05,670 --> 00:11:06,170
Right.

147
00:11:06,480 --> 00:11:07,950
So we have Maverick here.

148
00:11:08,160 --> 00:11:09,970
And what cell number should we use?

149
00:11:10,080 --> 00:11:10,700
Let's see.

150
00:11:11,130 --> 00:11:13,290
So we have here five.

151
00:11:13,290 --> 00:11:15,870
A five, a maverick was removed.

152
00:11:16,020 --> 00:11:16,490
All right.

153
00:11:16,500 --> 00:11:21,100
So now we want to add them to the end of the list of this list after he was removed.

154
00:11:21,360 --> 00:11:23,280
So this one is index zero.

155
00:11:23,310 --> 00:11:26,250
One, two, three, four.

156
00:11:26,430 --> 00:11:30,660
And actually, we want to add it to index number five right after Ashely.

157
00:11:31,020 --> 00:11:35,380
So that's, what, five here and run it.

158
00:11:36,960 --> 00:11:39,410
So again, you see, Maverick was added right here.

159
00:11:39,600 --> 00:11:46,470
So basically for this assignment and for other assignments as well, you have several solutions for

160
00:11:46,500 --> 00:11:47,190
this assignment.

161
00:11:47,190 --> 00:11:55,380
You can use this aband action or the insert action by stating that you want to inserted into index five.

162
00:11:55,740 --> 00:11:56,250
All right.

163
00:11:56,820 --> 00:11:59,850
And let's head over to the next one.

164
00:12:00,030 --> 00:12:05,190
And we would like to remove the battery from the team.

165
00:12:06,420 --> 00:12:10,980
He was making trouble, remove Patrick and not Patrick Maverick.

166
00:12:11,820 --> 00:12:16,260
Remove Maverick from the employee's.

167
00:12:18,560 --> 00:12:24,980
List because he did some trouble and then we have employees, Pop

168
00:12:27,140 --> 00:12:30,440
and Maverick inside the BOP.

169
00:12:31,420 --> 00:12:38,690
Oh, we don't even need to mention because if you recall, Pop removes the last item of the list.

170
00:12:39,290 --> 00:12:44,390
So all that sprint, this is the sixth assignment.

171
00:12:44,720 --> 00:12:45,950
Remove Patrick.

172
00:12:49,080 --> 00:12:50,520
Maverick oh.

173
00:12:53,600 --> 00:13:01,940
I have a friendly battery, so I always saying, Maverick, my mistake, a move maverick from the list.

174
00:13:07,000 --> 00:13:15,310
And employees, great, so we have removed them using pop again, pop removes the last item of the list

175
00:13:15,670 --> 00:13:19,810
and I sprinted, so he was removed.

176
00:13:19,990 --> 00:13:26,410
By the way, can anyone say if I stayed here, I can also stay here than the number of the cell?

177
00:13:26,440 --> 00:13:27,760
OK, let's do an example.

178
00:13:27,970 --> 00:13:29,860
Just stating here zero.

179
00:13:30,010 --> 00:13:34,210
And we should see that Adam would be removed after we run it.

180
00:13:34,870 --> 00:13:37,100
OK, so Adam was removed.

181
00:13:37,360 --> 00:13:43,060
OK, so anyone can tell me if I put here minus one.

182
00:13:43,720 --> 00:13:50,380
What minus one states for we've seen it in the theory part of BASIX and lists.

183
00:13:51,100 --> 00:13:53,950
So if I put here minus one, what will happen.

184
00:13:55,970 --> 00:14:03,520
OK, so Maverick was removed as well, because if you remember once you use the minus one regarding

185
00:14:03,520 --> 00:14:08,690
list, it addresses the last item of the list that I sell.

186
00:14:08,860 --> 00:14:14,110
So basically not mentioning it, mentioning here anything or mentioning minus one is the same.

187
00:14:14,980 --> 00:14:19,930
All right, I'll leave here the minus one just to stay, just to show that you can use any number here

188
00:14:19,930 --> 00:14:21,490
to remove any cell that you want.

189
00:14:22,390 --> 00:14:23,020
All right.

190
00:14:23,440 --> 00:14:25,840
So now we came up to the bonus.

191
00:14:25,960 --> 00:14:26,480
All right.

192
00:14:26,500 --> 00:14:27,850
We have the bonus.

193
00:14:29,110 --> 00:14:34,790
Simon, sort the list by ABC.

194
00:14:35,140 --> 00:14:38,830
So let's try to do it together, OK?

195
00:14:39,160 --> 00:14:43,690
So fight on short list.

196
00:14:46,240 --> 00:14:47,340
All right.

197
00:14:47,350 --> 00:14:58,930
So just picking a website here and the results and I can see here that by default, so it doesn't require

198
00:14:58,930 --> 00:15:00,180
any parameter.

199
00:15:00,430 --> 00:15:06,640
So we can see here the sort action and we can see here an example of the list.

200
00:15:08,020 --> 00:15:10,030
And this one is assort.

201
00:15:10,450 --> 00:15:13,170
So let's try to use this one.

202
00:15:13,180 --> 00:15:13,640
All right.

203
00:15:13,660 --> 00:15:23,950
So let's try the employees that sort of like this and try to print sorted lists like this

204
00:15:27,520 --> 00:15:36,910
and employees and casting staff like this.

205
00:15:38,120 --> 00:15:38,800
All right.

206
00:15:40,290 --> 00:15:41,200
There you have it.

207
00:15:41,380 --> 00:15:46,510
So it is sorted by ABC, this one, A, the G and J.

208
00:15:47,020 --> 00:15:47,500
All right.

209
00:15:47,510 --> 00:15:56,120
So we have just encountered of searching online for something that we need and for example, this sort

210
00:15:56,140 --> 00:15:59,710
action and this one was really easy to find.

211
00:15:59,740 --> 00:16:06,550
Basically, I just picked up the first result was searching for the phrase, before we finish, I just

212
00:16:06,550 --> 00:16:20,860
want to state that we use this website and also mention here all all rights reserved

213
00:16:23,140 --> 00:16:23,650
to.

214
00:16:24,550 --> 00:16:25,000
All right.

215
00:16:25,030 --> 00:16:28,320
This website that we've taken this example from.

216
00:16:29,200 --> 00:16:30,760
But you see, it's pretty easy.

217
00:16:31,930 --> 00:16:37,700
Just look it up in the Internet using simple phrases as you can and you can find it, find it easily.

218
00:16:37,870 --> 00:16:41,800
So this sort actually practices how actual developers work.

219
00:16:42,010 --> 00:16:44,890
So once they get an assignment, they don't know what to do.

220
00:16:44,890 --> 00:16:49,450
They can ask their friends, but also they can look it up in the Internet and find it instantly.

221
00:16:49,630 --> 00:16:50,650
It's not very hard.

222
00:16:50,860 --> 00:16:52,140
Just copy paste it.

223
00:16:52,240 --> 00:16:55,660
And usually if the things is simple, it works.

224
00:16:55,870 --> 00:16:57,450
And that's about it, guys.

225
00:16:57,640 --> 00:17:04,090
So we have finished the advanced practice regarding lists and see you in the next video.
