1
00:00:13,520 --> 00:00:15,360
Welcome to this video now.

2
00:00:15,380 --> 00:00:23,030
We will try to resolve top practice parts and all right, so once you open your projects, create a

3
00:00:23,030 --> 00:00:27,410
new file as always, and you can give it a meaningful name.

4
00:00:27,410 --> 00:00:39,440
For example, collections, double practice, and here also collections type of practice.

5
00:00:40,970 --> 00:00:41,510
Yeah.

6
00:00:42,230 --> 00:00:52,290
So the first assignment you were asked to create a double with double off tech terms.

7
00:00:52,400 --> 00:00:52,730
Yeah.

8
00:00:53,060 --> 00:00:55,410
So let's create it.

9
00:00:55,430 --> 00:01:05,630
It was tech, not loggi, called terms like that and topolice obviously with round brackets.

10
00:01:05,630 --> 00:01:07,160
And we had Python here.

11
00:01:10,860 --> 00:01:12,210
And then picture.

12
00:01:15,090 --> 00:01:15,690
Topal.

13
00:01:18,000 --> 00:01:22,500
Collections and string like that.

14
00:01:23,280 --> 00:01:25,480
Yeah, so let's try to print it.

15
00:01:25,500 --> 00:01:29,620
So this is the first assignment.

16
00:01:29,940 --> 00:01:38,130
This is the Toppo collection and we have a year plus and technological terms like that.

17
00:01:38,700 --> 00:01:45,930
So what we did here basically just create a basic Thorpdale as what we had in the first assignment and

18
00:01:45,930 --> 00:01:46,810
then just print it.

19
00:01:46,950 --> 00:01:48,350
Let's see that we are OK.

20
00:01:50,010 --> 00:01:50,460
Great.

21
00:01:50,470 --> 00:01:54,060
So the top is printed successfully and from here.

22
00:01:54,090 --> 00:01:56,550
Let's go straight forward to the next assignment.

23
00:01:56,940 --> 00:02:02,430
And the second assignment was let's just mark here that this is assignment number one as well.

24
00:02:03,090 --> 00:02:04,290
Yeah, like that.

25
00:02:04,650 --> 00:02:12,330
An assignment number two was to print a sentence using.

26
00:02:17,380 --> 00:02:21,820
Using cell extraction.

27
00:02:23,410 --> 00:02:29,600
Regular, regular and Nygård negative.

28
00:02:29,690 --> 00:02:37,310
Yeah, so because the sentence is a bit long, I have it here on the other screen, so I'm just going

29
00:02:37,310 --> 00:02:41,870
to copy it to the publisher so it will be easier to print it.

30
00:02:42,950 --> 00:02:46,420
So this is the sense, the sentence we have error here.

31
00:02:47,150 --> 00:02:52,130
So we just put the comment Mark before it and we'll be fine.

32
00:02:52,760 --> 00:02:54,770
So let's put it here in the beginning.

33
00:02:54,800 --> 00:02:55,700
Yeah, like that.

34
00:02:56,120 --> 00:02:57,530
So this is the sentence.

35
00:02:57,710 --> 00:02:58,930
We're ninja developers.

36
00:02:58,940 --> 00:03:06,140
We write Python called in by Charmides and now practicing tuple collection stuff that contains a string

37
00:03:06,140 --> 00:03:07,050
of variables.

38
00:03:07,580 --> 00:03:17,810
So we have the words here and that's just try to print it as we were asked by using negative and regular

39
00:03:18,320 --> 00:03:19,020
extraction.

40
00:03:19,400 --> 00:03:23,390
So first of all, let's mark here that this is assignment number two.

41
00:03:23,600 --> 00:03:26,650
And let's begin first of all, we have regular words.

42
00:03:26,660 --> 00:03:26,960
All right.

43
00:03:26,980 --> 00:03:33,400
So we have we are ninja developers, right?

44
00:03:33,800 --> 00:03:34,940
And then we.

45
00:03:37,580 --> 00:03:49,670
We write and then we have the first word, which is we write Python and we marked it as a regular extraction.

46
00:03:50,060 --> 00:03:56,060
So regular extraction, it's this cell and this cell's index in regular extraction is zero.

47
00:03:56,330 --> 00:03:58,460
So let's just extract it.

48
00:03:59,030 --> 00:04:01,040
That's do a plus sign outside.

49
00:04:01,040 --> 00:04:06,170
It's outside the quotation mark because we want to insert a variable.

50
00:04:06,290 --> 00:04:07,460
So we do it like this.

51
00:04:07,550 --> 00:04:12,230
And then we just mention here the tuple and inside the square brackets.

52
00:04:12,440 --> 00:04:15,350
We just mention the cell number like that.

53
00:04:16,640 --> 00:04:23,110
Let's just print it for now so we'll know that we'll find that's our solution way is OK.

54
00:04:23,630 --> 00:04:24,050
Yeah.

55
00:04:25,190 --> 00:04:27,400
So it looks good so far, right.

56
00:04:28,130 --> 00:04:29,450
We are ninja developers.

57
00:04:29,450 --> 00:04:30,440
We write Python.

58
00:04:30,440 --> 00:04:30,630
Right.

59
00:04:30,650 --> 00:04:32,300
So, so far, so good.

60
00:04:32,870 --> 00:04:38,690
So from here inside the round brackets, because this is our present, you see it's marked in yellow

61
00:04:38,690 --> 00:04:38,990
here.

62
00:04:39,290 --> 00:04:42,210
So inside the round brackets, we want to continue.

63
00:04:42,230 --> 00:04:45,350
So we do it plus again and quotation marks to continue.

64
00:04:45,590 --> 00:04:52,930
And we write you code, right, because we're continuing starting from this word.

65
00:04:52,940 --> 00:04:54,440
So we need to continue this way.

66
00:04:54,440 --> 00:04:54,680
Right.

67
00:04:54,980 --> 00:05:01,370
Called in this regular string in and then we have PI charm.

68
00:05:01,790 --> 00:05:02,100
Right.

69
00:05:02,480 --> 00:05:09,150
So Pi Chameides was marked as negative extraction and we can start counting from here.

70
00:05:09,170 --> 00:05:16,330
This is, this cell is number minus one, negative counting minus two, minus three and minus four.

71
00:05:16,520 --> 00:05:22,610
So we need to mention the part, the tuple and inside the square brackets to.

72
00:05:22,610 --> 00:05:23,210
Right.

73
00:05:23,360 --> 00:05:24,260
Minus four.

74
00:05:24,320 --> 00:05:25,580
So I'm just going to copy it.

75
00:05:26,120 --> 00:05:27,050
Changed the number.

76
00:05:28,490 --> 00:05:28,910
Yeah.

77
00:05:28,910 --> 00:05:29,510
Right here.

78
00:05:29,900 --> 00:05:32,660
Plus and then right.

79
00:05:32,660 --> 00:05:33,620
Click and based.

80
00:05:34,040 --> 00:05:35,270
We have two classes here.

81
00:05:35,900 --> 00:05:36,280
Yeah.

82
00:05:36,290 --> 00:05:41,660
And inside the square brackets put minus four like that again.

83
00:05:41,660 --> 00:05:44,930
Let's just try to print it to see that we're in the right way.

84
00:05:46,010 --> 00:05:50,510
So we're ninja developers, we write Python called in pi charm.

85
00:05:50,510 --> 00:05:52,490
You see we have a small issue here.

86
00:05:53,030 --> 00:05:53,930
We don't have space.

87
00:05:53,940 --> 00:05:59,780
So after Python we need to put a space right here where the cursor is marking, blinking right now.

88
00:06:00,210 --> 00:06:03,170
So right here, let's try to print it again.

89
00:06:04,560 --> 00:06:05,520
And we're good.

90
00:06:06,150 --> 00:06:09,840
All right, so we are good to go.

91
00:06:11,430 --> 00:06:14,770
Let me just add here by picture ID, right.

92
00:06:15,390 --> 00:06:17,510
So let's run it.

93
00:06:18,300 --> 00:06:18,600
Yeah.

94
00:06:18,600 --> 00:06:20,910
By Charmides so let's continue.

95
00:06:21,030 --> 00:06:27,030
And after picture I.D., we have this and now practicing topical collections.

96
00:06:27,310 --> 00:06:32,550
And our next word is Toppo.

97
00:06:32,670 --> 00:06:33,090
Right.

98
00:06:33,270 --> 00:06:34,680
So this is our next word.

99
00:06:34,720 --> 00:06:38,640
So until this point, we just add a regular string again.

100
00:06:38,820 --> 00:06:45,120
So we have Bloss quotation mark and codine by Charmides and we have a comma.

101
00:06:45,210 --> 00:06:50,180
Right, because is this comma right here after Charmides, this comma right here.

102
00:06:50,520 --> 00:06:57,750
So we put the comma and and now back to seeing Toppo.

103
00:06:58,470 --> 00:07:01,830
Top Ball is marked for us in

104
00:07:04,260 --> 00:07:07,610
positive meaning, regular extraction.

105
00:07:07,890 --> 00:07:15,090
So we just put here a technological term and two because we have zero one and two.

106
00:07:15,690 --> 00:07:16,670
Right subtable.

107
00:07:16,680 --> 00:07:25,950
We extracted tuple right now and after tuple we have collection stop that will constrain string variables.

108
00:07:25,950 --> 00:07:28,260
So string is our next word.

109
00:07:28,260 --> 00:07:30,330
This one is our last extraction.

110
00:07:30,960 --> 00:07:33,410
So right now we are in trouble.

111
00:07:33,420 --> 00:07:35,020
So we need to continue from here.

112
00:07:35,310 --> 00:07:36,010
You know what?

113
00:07:36,120 --> 00:07:37,420
Let me just copy this one.

114
00:07:37,500 --> 00:07:38,730
Yeah, it's the same way.

115
00:07:38,740 --> 00:07:39,300
Copy.

116
00:07:39,420 --> 00:07:45,180
Just going to show you some shortcuts because instead of writing it in the keyboard, you can also copy

117
00:07:45,180 --> 00:07:45,360
it.

118
00:07:45,600 --> 00:07:49,800
So plus quotation marks and inside quotation mark, we can just.

119
00:07:49,980 --> 00:07:50,280
Right.

120
00:07:50,280 --> 00:07:51,210
Click and paste it.

121
00:07:51,210 --> 00:07:51,480
Right.

122
00:07:51,840 --> 00:07:52,470
The same thing.

123
00:07:53,730 --> 00:07:59,130
And now we need to extract the string, which is the last cell.

124
00:07:59,280 --> 00:08:02,820
And we were asked to do it in negative extraction.

125
00:08:02,830 --> 00:08:09,050
So just mentioning here plus in technological terms and square brackets minus one.

126
00:08:09,360 --> 00:08:09,690
Yeah.

127
00:08:10,140 --> 00:08:10,790
Like that.

128
00:08:11,070 --> 00:08:16,890
So now we need to just add the last word plus.

129
00:08:20,250 --> 00:08:29,010
Quotation marks and variables, yeah, like that, you see, it's it's a very, very long and we have

130
00:08:29,010 --> 00:08:29,850
a line here.

131
00:08:29,850 --> 00:08:32,940
Yeah, we have a line that goes from top to bottom right here.

132
00:08:33,270 --> 00:08:36,490
And we cannot market it because it's on the background.

133
00:08:36,630 --> 00:08:39,330
We'll see what we'll do it with it in a minute.

134
00:08:39,540 --> 00:08:42,030
That's just print it for now and see that we are OK.

135
00:08:43,010 --> 00:08:44,940
So we're in ninja developers.

136
00:08:45,090 --> 00:08:51,840
We write Python called in by Charmides and nonpracticing tuple collections topic that contains string

137
00:08:51,840 --> 00:08:52,560
variables.

138
00:08:52,800 --> 00:08:54,360
That's for now.

139
00:08:54,360 --> 00:08:56,880
Just add here a space after tuple.

140
00:08:58,320 --> 00:08:58,680
Yep.

141
00:08:58,860 --> 00:09:02,120
So practicing right here.

142
00:09:02,130 --> 00:09:02,490
Yeah.

143
00:09:04,200 --> 00:09:06,150
So now we should be fine.

144
00:09:06,460 --> 00:09:06,870
Yeah.

145
00:09:06,870 --> 00:09:08,100
So it's the same thing.

146
00:09:08,370 --> 00:09:15,900
We have the same sentence in the output as we were asked to do like that.

147
00:09:16,230 --> 00:09:16,500
Yeah.

148
00:09:16,500 --> 00:09:19,050
It's the same one is going to raise it.

149
00:09:20,940 --> 00:09:24,150
So we were great in this assignment.

150
00:09:24,420 --> 00:09:28,440
So you can see like the background line here that goes from top to bottom.

151
00:09:28,440 --> 00:09:36,090
It goes from from here under the name of the collection dictionary practice advanced here, the marker.

152
00:09:36,270 --> 00:09:40,440
And it goes through this word now and you can see line here.

153
00:09:40,740 --> 00:09:46,430
So if you see line it, it's here because PI Charm advises us not to cross this line.

154
00:09:46,620 --> 00:09:50,250
So our code would be would look static.

155
00:09:50,460 --> 00:09:52,560
So we don't want to cross this line.

156
00:09:52,560 --> 00:09:56,460
So everything that we have here, we would like not to cross this line.

157
00:09:56,460 --> 00:10:00,900
So the thing I'm going to do is right here to just hit enter.

158
00:10:02,790 --> 00:10:09,030
All right, they didn't do the job, so let's go a little bit back and forth here under a lot right

159
00:10:09,030 --> 00:10:12,930
after the four just hit enter here, right.

160
00:10:13,140 --> 00:10:15,750
And just backspace, the whole thing.

161
00:10:18,000 --> 00:10:25,180
Yeah, like that, and now for some reason, I have erased it.

162
00:10:25,200 --> 00:10:32,400
Yeah, so you see, for some reason I raised the square brackets here, so I just edit it, edit it

163
00:10:32,400 --> 00:10:33,500
in now.

164
00:10:33,840 --> 00:10:34,280
All right.

165
00:10:34,290 --> 00:10:38,340
We were OK, we're all we just passed the line a little bit.

166
00:10:38,340 --> 00:10:39,150
But that's all right.

167
00:10:39,330 --> 00:10:44,070
We're not we didn't not pass it a lot like it was before and now it looks more static.

168
00:10:44,070 --> 00:10:48,390
So you just hit the enter and make sure we don't have any errors.

169
00:10:48,600 --> 00:10:53,790
And you see, I hit the intro right after the square brackets here after the four.

170
00:10:54,030 --> 00:10:57,290
And let's just try to print it and see that we were OK.

171
00:10:57,480 --> 00:10:57,860
Yeah.

172
00:10:57,870 --> 00:10:59,670
So to see the output is fine.

173
00:10:59,790 --> 00:11:05,400
We didn't break anything and we're good to go for to the third assignment.

174
00:11:05,700 --> 00:11:11,610
So we have completed successfully the second assignment of printing out the sentence using negative

175
00:11:11,610 --> 00:11:14,220
and positive extraction.

176
00:11:15,000 --> 00:11:23,520
And the third assignment we were asked to do the following thing, insert float.

177
00:11:25,780 --> 00:11:36,640
And list variables into the tuple, so as you recall in the previous video, not the previous like the

178
00:11:36,640 --> 00:11:42,040
one before it once we discussed advanced Toppo, we mentioned the tuple.

179
00:11:42,730 --> 00:11:44,740
We cannot add variables.

180
00:11:44,740 --> 00:11:46,840
We can add cells into Toppo.

181
00:11:46,840 --> 00:11:49,020
We cannot modify it or delete it.

182
00:11:49,270 --> 00:11:57,940
So the trick here is to create a new collection of list and to pass all the items from the tuple to

183
00:11:57,940 --> 00:11:58,480
the list.

184
00:11:58,570 --> 00:12:07,540
And in the list we will add some new cells and then we will cast the list back to topple.

185
00:12:07,930 --> 00:12:08,250
Right.

186
00:12:08,590 --> 00:12:12,540
So you can see it, by the way, you can see it in the advanced part of tuple.

187
00:12:12,730 --> 00:12:18,590
There is an attachment file with all the material and you can see the example one by one right there.

188
00:12:18,820 --> 00:12:23,770
So first of all, let's create a deck technological terms list.

189
00:12:24,070 --> 00:12:27,090
Yeah, this would be a new collection.

190
00:12:27,760 --> 00:12:28,150
Yeah.

191
00:12:28,450 --> 00:12:35,940
And then we just mentioned we just do a casting of list and mention inside our toppled.

192
00:12:36,190 --> 00:12:42,780
So what we did here, actually we have casted our tuple into a list.

193
00:12:42,870 --> 00:12:43,210
Right.

194
00:12:43,510 --> 00:12:46,930
This one is casting same as we do in the printout.

195
00:12:46,930 --> 00:12:47,300
Right.

196
00:12:47,500 --> 00:12:48,940
Same as you did right here.

197
00:12:49,210 --> 00:12:51,560
We casted the top into a string.

198
00:12:51,580 --> 00:12:53,890
So now we're casting the tuple into a list.

199
00:12:54,100 --> 00:12:55,810
And this would be our list.

200
00:12:55,930 --> 00:13:04,360
And once we were dealing with a list, yeah, we can add new items so you can see the lecture that handles

201
00:13:04,540 --> 00:13:09,490
lists, the advanced part of lists that we previously studied.

202
00:13:09,670 --> 00:13:12,430
And you can see there how to add new cells.

203
00:13:12,640 --> 00:13:16,030
And the way to add new cells is using append action.

204
00:13:16,060 --> 00:13:16,390
All right.

205
00:13:18,880 --> 00:13:25,690
So we'll use a band and inside quotation marks, single double doesn't matter, we just add the items

206
00:13:25,690 --> 00:13:31,990
float and we will add the item list like that.

207
00:13:32,710 --> 00:13:38,710
And once we are done and again, we will mention the tuple equals.

208
00:13:38,890 --> 00:13:42,910
And now what we need to do is to cast the list.

209
00:13:43,090 --> 00:13:43,510
Yeah.

210
00:13:43,630 --> 00:13:45,820
This one back to topple.

211
00:13:46,000 --> 00:13:49,750
Right, with the new items inside it.

212
00:13:51,610 --> 00:13:51,930
All right.

213
00:13:51,940 --> 00:13:53,370
So you see what we did here?

214
00:13:53,380 --> 00:13:54,400
We have three steps.

215
00:13:54,400 --> 00:13:59,290
We have step number one, where we took the tuple and casted it into a list.

216
00:13:59,710 --> 00:14:01,390
And this will be our list.

217
00:14:01,930 --> 00:14:06,520
Then once we handle with the list, we added new items using a band action key.

218
00:14:07,210 --> 00:14:12,520
And the third step was to take this list and to cast it back.

219
00:14:12,520 --> 00:14:18,610
To topple and or topple will be equals to what we have here with the new items.

220
00:14:18,730 --> 00:14:22,690
And once we did that, we can just print it and have the new items inside.

221
00:14:25,540 --> 00:14:29,830
This is our new poll with the added cels.

222
00:14:30,930 --> 00:14:31,350
Yeah.

223
00:14:34,540 --> 00:14:37,910
Let's see the magic run.

224
00:14:38,620 --> 00:14:46,740
Yeah, so you can see here the output is successful, we have added float and less to support successfully.

225
00:14:47,290 --> 00:14:47,740
Great.

226
00:14:47,750 --> 00:14:50,300
So this was wasn't an easy assignment.

227
00:14:50,320 --> 00:14:51,340
This was a bit hard.

228
00:14:51,800 --> 00:14:57,940
So because we needed to involve your list also together with Toppo, but this is what programming is

229
00:14:57,940 --> 00:14:58,480
all about.

230
00:14:58,690 --> 00:15:03,730
You need to mix all the topics all together, because eventually when you're going to write code, you're

231
00:15:03,730 --> 00:15:10,180
going to use all the topics mixed together with string variables, lists, loops, eve statements all

232
00:15:10,210 --> 00:15:10,720
together.

233
00:15:11,090 --> 00:15:14,050
So it's a great example, great practice right here.

234
00:15:15,460 --> 00:15:23,050
And the first fourth assignment was to create a single cell tuple.

235
00:15:23,290 --> 00:15:23,710
Yeah.

236
00:15:24,040 --> 00:15:28,480
So single cell Toppo like that.

237
00:15:28,840 --> 00:15:32,100
And right here we studied that.

238
00:15:32,110 --> 00:15:39,790
What we need to do is not to leave it like this, but to add the camera here and then just print the

239
00:15:39,790 --> 00:15:40,450
single.

240
00:15:42,020 --> 00:15:43,130
Sell to Apple.

241
00:15:43,690 --> 00:15:53,480
Yeah, as always, just mentioning enter and also you were asked to bring the type of the top.

242
00:15:53,590 --> 00:15:55,680
You know what, you don't need to add a string here.

243
00:15:55,710 --> 00:16:02,360
Just mentioned the single celled Dupo and around it.

244
00:16:03,170 --> 00:16:10,160
Just use the action key type with round brackets.

245
00:16:10,550 --> 00:16:12,970
Let's print it and see that we're OK.

246
00:16:13,730 --> 00:16:14,140
Great.

247
00:16:14,210 --> 00:16:18,520
So we have printed it and also we can see here the type that is tuple.

248
00:16:19,250 --> 00:16:19,870
All right.

249
00:16:19,890 --> 00:16:23,360
This just add here a marker that it's the fourth assignment.

250
00:16:23,580 --> 00:16:27,240
And let's see what happens if we just remove the comma from here.

251
00:16:27,260 --> 00:16:27,530
All right.

252
00:16:27,740 --> 00:16:29,000
Let's just remove the comma.

253
00:16:29,690 --> 00:16:33,710
Once we remove the common, print it immediately.

254
00:16:33,890 --> 00:16:40,400
You can see here that the variable that mentions here in the type is integer.

255
00:16:40,400 --> 00:16:41,570
It became an integer.

256
00:16:41,660 --> 00:16:45,590
So only if you leave here the comma, this becomes a double.

257
00:16:45,830 --> 00:16:49,790
If you if you remove the comma, it's not double anymore.

258
00:16:49,790 --> 00:16:50,930
It becomes a variable.

259
00:16:50,990 --> 00:16:51,220
All right.

260
00:16:51,230 --> 00:16:56,860
So this very important thing and I think that we are done OK.

261
00:16:56,870 --> 00:17:00,530
So we have completed successfully the practice part of tuple.

262
00:17:01,010 --> 00:17:05,240
This was not an easy assignment list right here.

263
00:17:05,460 --> 00:17:12,920
And by now you can tap yourself on the shoulder and tell yourself, good job, because we have completed

264
00:17:12,920 --> 00:17:18,380
successfully all the variables part of the course and also all the collection part of the course.

265
00:17:18,650 --> 00:17:21,170
And that's a meaningful part.

266
00:17:21,320 --> 00:17:21,650
All right.

267
00:17:21,650 --> 00:17:26,150
That's about thirty or forty 40 percent of the python part.

268
00:17:26,360 --> 00:17:29,690
And we can go straight forward to the next topic.

269
00:17:30,050 --> 00:17:31,700
So that's about it.

270
00:17:31,700 --> 00:17:33,830
And I will see you in the next video.
