1 00:00:02,048 --> 00:00:04,352 ‫Now let's move on to list 2 00:00:06,144 --> 00:00:08,704 ‫Lists are very similar to string 3 00:00:08,960 --> 00:00:11,776 ‫Except that each element can be of any type. 4 00:00:12,032 --> 00:00:14,080 ‫In a string each element 5 00:00:14,336 --> 00:00:15,616 ‫Was the character 6 00:00:16,384 --> 00:00:17,664 ‫But in list 7 00:00:17,920 --> 00:00:19,968 ‫Each element can be of any type. 8 00:00:21,248 --> 00:00:25,088 ‫So to define a list we have to use square bracket 9 00:00:25,344 --> 00:00:29,440 ‫So if I write L1 L1 is a variable name 10 00:00:29,696 --> 00:00:34,560 ‫Then in a square bracket if I write 1234 11 00:00:37,632 --> 00:00:39,168 ‫12345 12 00:00:39,680 --> 00:00:40,704 ‫And run this 13 00:00:40,960 --> 00:00:42,752 ‫L1 is our list. 14 00:00:43,776 --> 00:00:45,824 ‫To check right type 15 00:00:49,408 --> 00:00:50,176 ‫L1 16 00:00:52,736 --> 00:00:56,576 ‫It is showing that the type of L1 character is list 17 00:00:57,600 --> 00:01:01,696 ‫To print all its value we write print L1 18 00:01:07,584 --> 00:01:10,656 ‫And we are getting all the values that L1 is containing 19 00:01:13,472 --> 00:01:19,616 ‫Just like strings we can also use the same ####### techniques to manipulate list. 20 00:01:20,128 --> 00:01:21,408 ‫So if I write 21 00:01:22,432 --> 00:01:23,968 ‫L1 22 00:01:24,224 --> 00:01:26,016 ‫Square bracket 23 00:01:27,040 --> 00:01:27,808 ‫Zero 24 00:01:30,112 --> 00:01:31,136 ‫This will give me 25 00:01:31,648 --> 00:01:35,488 ‫Element present at the 0th location Which is one 26 00:01:35,744 --> 00:01:40,864 ‫So here one is that location 0,2 is at the location 27 00:01:41,376 --> 00:01:41,888 ‫1 28 00:01:42,400 --> 00:01:44,448 ‫3 is at location 2 29 00:01:44,704 --> 00:01:47,008 ‫4 at 3 and 5 at 4. 30 00:01:47,776 --> 00:01:52,384 ‫Just like a string I can use colon to select multiple 31 00:01:52,640 --> 00:01:53,664 ‫Element 32 00:01:53,920 --> 00:01:56,480 ‫If I write 0 colon 3 33 00:01:58,528 --> 00:02:00,832 ‫Will give me the first 3 elements 34 00:02:01,088 --> 00:02:04,160 ‫Here the location 3 is excluded so I will get 35 00:02:04,416 --> 00:02:05,184 ‫Elements 36 00:02:05,440 --> 00:02:09,792 ‫Present at location 0, location 1 and location 2 37 00:02:10,048 --> 00:02:11,328 ‫3 is excluded 38 00:02:11,584 --> 00:02:14,144 ‫Just like slicing in a string 39 00:02:14,400 --> 00:02:16,192 ‫You can also use step 40 00:02:16,704 --> 00:02:19,008 ‫So if I write L1 41 00:02:20,544 --> 00:02:25,152 ‫Now if I want to select all the elements I will just right colon 42 00:02:25,664 --> 00:02:27,456 ‫Then I will write another colon 43 00:02:28,224 --> 00:02:34,368 ‫So first argument was for the starting location second argument was for the 44 00:02:34,624 --> 00:02:38,208 ‫Stopping location and the third argument is for the steps. 45 00:02:38,464 --> 00:02:43,328 ‫We are not giving starting and stopping location since we want all the elements. 46 00:02:43,584 --> 00:02:46,144 ‫Now we are defining step as two 47 00:02:46,400 --> 00:02:49,728 ‫So it will give me all the alternate elements of my list 48 00:02:52,032 --> 00:02:57,920 ‫So again it is ignoring 2 and 4 since we provided Step of 2. 49 00:03:01,760 --> 00:03:05,856 ‫It is not necessary for list to have all the elements of same type 50 00:03:06,880 --> 00:03:12,256 ‫You can assign different types of element in a single list so if I write L2 51 00:03:12,512 --> 00:03:13,536 ‫Equal to 52 00:03:14,048 --> 00:03:14,816 ‫Square bracket 53 00:03:15,072 --> 00:03:15,840 ‫1 54 00:03:16,096 --> 00:03:16,864 ‫Comma 55 00:03:17,888 --> 00:03:21,728 ‫I want to provide a string I will write in double quotation 56 00:03:21,984 --> 00:03:22,496 ‫A 57 00:03:24,544 --> 00:03:29,664 ‫Comma if I want to provide floating point numbers I will write 1.0 58 00:03:30,944 --> 00:03:31,968 ‫And if I run this 59 00:03:34,528 --> 00:03:40,672 ‫My ######## is created and the data type of my first element is ####### second element is a string and the 60 00:03:40,928 --> 00:03:41,952 ‫third ####### is ####### 61 00:03:44,000 --> 00:03:45,280 ‫But we can assign 62 00:03:45,536 --> 00:03:48,096 ‫All this in a single list as well. 63 00:03:50,912 --> 00:03:57,056 ‫So if you want to check you can check using the type operators write type 64 00:03:57,312 --> 00:04:03,456 ‫Now inside L2 I want the data type of first elements I will write zero 65 00:04:04,992 --> 00:04:08,064 ‫And it is end because one is our end 66 00:04:08,832 --> 00:04:11,392 ‫If I write type 67 00:04:12,672 --> 00:04:13,696 ‫Do 68 00:04:13,952 --> 00:04:16,256 ‫Square bracket 1 69 00:04:17,536 --> 00:04:23,679 ‫Which is string because our a is an double quotation and we have provided it as a string 70 00:04:23,935 --> 00:04:25,215 ‫write L2 71 00:04:27,007 --> 00:04:31,615 ‫Our L2 is a list that's why we just write type of L2 72 00:04:31,871 --> 00:04:33,407 ‫It will showing us list. 73 00:04:34,943 --> 00:04:39,807 ‫We can also provide list as a element of another list 74 00:04:40,063 --> 00:04:43,135 ‫So we write L3 equal to 75 00:04:45,951 --> 00:04:46,719 ‫L2 76 00:04:49,023 --> 00:04:50,303 ‫Comma 77 00:04:50,815 --> 00:04:51,583 ‫1 78 00:04:53,375 --> 00:04:54,399 ‫Comma 79 00:04:54,655 --> 00:04:55,679 ‫2.0 80 00:04:58,239 --> 00:05:00,287 ‫If you run this command 81 00:05:00,543 --> 00:05:02,079 ‫So we have provided list 82 00:05:02,335 --> 00:05:06,175 ‫L2 list inside L3 so if we print L3 83 00:05:08,991 --> 00:05:13,343 ‫Here our first element is a list which is L2 84 00:05:14,111 --> 00:05:17,695 ‫and our second element is int and third element is 85 00:05:17,951 --> 00:05:18,463 ‫float. 86 00:05:19,231 --> 00:05:21,279 ‫So just to check if we write 87 00:05:22,303 --> 00:05:23,071 ‫Type of 88 00:05:23,327 --> 00:05:26,143 ‫L3 89 00:05:27,679 --> 00:05:29,215 ‫Comma zero 90 00:05:29,983 --> 00:05:34,591 ‫This is showing us a list because we have provided L2 inside of L3 91 00:05:36,127 --> 00:05:36,639 ‫Now 92 00:05:37,407 --> 00:05:40,991 ‫We are mentioned how to select the first element of L3 93 00:05:41,247 --> 00:05:42,783 ‫We can just write L3 94 00:05:43,295 --> 00:05:45,087 ‫And in bracket we can write 0. 95 00:05:46,111 --> 00:05:50,719 ‫This will give us the first element of my first element is a list 96 00:05:50,975 --> 00:05:53,791 ‫How to select first element of that list? 97 00:05:54,303 --> 00:05:55,327 ‫We can write 98 00:05:55,583 --> 00:05:56,351 ‫L3 99 00:05:59,167 --> 00:06:02,239 ‫Square bracket I will first write zero 100 00:06:02,495 --> 00:06:05,055 ‫Right now I am exercising 101 00:06:05,311 --> 00:06:07,103 ‫My first element which is the list 102 00:06:07,359 --> 00:06:10,943 ‫Now if I want the second element of this list 103 00:06:11,455 --> 00:06:14,015 ‫I will write in a square bracket 1 104 00:06:15,039 --> 00:06:17,343 ‫If I run this command it will give us 105 00:06:18,111 --> 00:06:21,951 ‫Character A this type of list are called 106 00:06:22,207 --> 00:06:26,047 ‫Nested lists because we have list inside a list. 107 00:06:28,095 --> 00:06:33,215 ‫Now you can also create list using special functions such as ####### 108 00:06:33,471 --> 00:06:35,775 ‫If I write list 109 00:06:37,311 --> 00:06:40,639 ‫And in bracket write range 110 00:06:40,895 --> 00:06:45,759 ‫In range I have to provide starting point stopping point ####### 111 00:06:46,015 --> 00:06:52,159 ‫So if I provide 0 as my starting point 10 as my stopping point 112 00:06:52,415 --> 00:06:53,951 ‫And step as 113 00:06:54,463 --> 00:06:55,231 ‫2 114 00:06:56,511 --> 00:06:57,791 ‫And if I run this 115 00:06:58,047 --> 00:07:00,607 ‫Range will provide me an output 116 00:07:01,375 --> 00:07:04,447 ‫Of 02468 117 00:07:04,959 --> 00:07:10,079 ‫And I am using list keyword to convert this output in the form of 118 00:07:10,335 --> 00:07:10,847 ‫List. 119 00:07:12,639 --> 00:07:16,735 ‫So we can create another variable l4 equal to 120 00:07:20,831 --> 00:07:22,367 ‫List 121 00:07:22,879 --> 00:07:27,743 ‫Range 0 to 10 with step 2. 122 00:07:33,375 --> 00:07:36,703 ‫If we print a variable l4 123 00:07:39,775 --> 00:07:42,847 ‫We can see zero is our first element 124 00:07:43,615 --> 00:07:47,199 ‫246 and then 8 if you want to sort it 125 00:07:47,967 --> 00:07:52,575 ‫The descending order we'll write L4 as sort, sort is a function 126 00:07:53,087 --> 00:07:59,231 ‫And the argument here is Reverse equal to true if you don't give this reverse equal to true 127 00:07:59,487 --> 00:08:04,095 ‫It will automatically sorted in the ascending order but we want it in the descending order 128 00:08:04,351 --> 00:08:07,423 ‫That's why we are providing argument rivers equal to true 129 00:08:07,935 --> 00:08:09,727 ‫Now if we check L4 130 00:08:09,983 --> 00:08:10,751 ‫You can see 131 00:08:11,519 --> 00:08:16,383 ‫It is sorted in the descending order or first element is 8 which is the 132 00:08:16,639 --> 00:08:17,407 ‫Largest 133 00:08:17,663 --> 00:08:20,735 ‫And the last element is zero the smallest element. 134 00:08:23,551 --> 00:08:26,367 ‫If you want to add more elements into 135 00:08:26,623 --> 00:08:27,391 ‫Our list 136 00:08:27,903 --> 00:08:33,279 ‫We can use append function will write L4 137 00:08:33,535 --> 00:08:34,815 ‫Dot append 138 00:08:37,631 --> 00:08:38,655 ‫And in bracket 139 00:08:38,911 --> 00:08:40,191 ‫Mentioned 140 00:08:40,447 --> 00:08:41,215 ‫Variable 141 00:08:41,471 --> 00:08:43,263 ‫Here we are writing pen 142 00:08:45,311 --> 00:08:46,591 ‫This 143 00:08:46,847 --> 00:08:47,615 ‫Add 144 00:08:47,871 --> 00:08:50,431 ‫The value 10 at the end of the list 145 00:08:50,687 --> 00:08:51,711 ‫You can see 146 00:08:52,223 --> 00:08:54,271 ‫We have 10 at the end of the list 147 00:08:55,295 --> 00:08:59,903 ‫If you want to change value of any element we can just write 148 00:09:00,927 --> 00:09:05,279 ‫That element address so L4 square bracket zero 149 00:09:06,815 --> 00:09:10,911 ‫This is our first element and we want the value of this element 150 00:09:11,167 --> 00:09:14,751 ‫To be three equal so if we write equal to 3 151 00:09:15,519 --> 00:09:18,079 ‫It will automatically change the value of 152 00:09:18,591 --> 00:09:20,127 ‫Of the first element to 3 153 00:09:20,383 --> 00:09:23,455 ‫So there it was it now the value is 3 154 00:09:26,015 --> 00:09:30,879 ‫If you want to change values of multiple elements we can write 155 00:09:31,647 --> 00:09:32,671 ‫L4 156 00:09:34,207 --> 00:09:38,303 ‫I want to change the value of second and third will write one 157 00:09:40,607 --> 00:09:45,215 ‫Colon three this means element second and third 158 00:09:45,471 --> 00:09:47,263 ‫since 3 is not included 159 00:09:48,543 --> 00:09:49,823 ‫And one is included. 160 00:09:50,335 --> 00:09:52,383 ‫And then in the square bracket 161 00:09:53,919 --> 00:09:57,759 ‫You can write the values for ignore if we write 5, 7 162 00:10:00,063 --> 00:10:06,207 ‫Now we are replacing this 6 to 5 in this 4 to 7 so we'll run this and 163 00:10:09,023 --> 00:10:11,583 ‫You can see the values are now changed. 164 00:10:12,351 --> 00:10:17,471 ‫In a way we are providing another list to replace the elements of this list. 165 00:10:21,567 --> 00:10:25,919 ‫Now if you want to insert an element at an specific index 166 00:10:26,175 --> 00:10:31,551 ‫Will do this by using a Keyword insert if we right L4 167 00:10:32,063 --> 00:10:33,855 ‫Insert 168 00:10:34,623 --> 00:10:36,415 ‫And we want to insert 169 00:10:36,671 --> 00:10:39,999 ‫This element at the first position will write zero 170 00:10:40,511 --> 00:10:41,791 ‫since 0 is our 1st 171 00:10:42,303 --> 00:10:45,375 ‫Position will write 15. 172 00:10:46,655 --> 00:10:52,543 ‫If we write 15 in double quotation this means we are passing this element as a string 173 00:10:52,799 --> 00:10:54,847 ‫So let's do this 174 00:10:59,455 --> 00:11:00,223 ‫You can see 175 00:11:00,479 --> 00:11:03,039 ‫We have inserted this 15 string 176 00:11:03,807 --> 00:11:08,415 ‫At the first position now all my other elements 177 00:11:08,671 --> 00:11:10,719 ‫are shifted by one space 178 00:11:10,975 --> 00:11:17,119 ‫Now if you want to remove element of this string we can do this 179 00:11:17,375 --> 00:11:22,751 ‫By using two commands first visit remove function and the second is the delete function 180 00:11:23,263 --> 00:11:29,407 ‫Remove function will remove the value of that element so for example if I write remove 181 00:11:30,175 --> 00:11:36,319 ‫Bracket 3 and 4 dot remove bracket 3 it will first search the element 182 00:11:36,575 --> 00:11:37,855 ‫Which have the value 3 183 00:11:38,367 --> 00:11:43,743 ‫That is this is the second element so it will delete this second element from this. 184 00:11:46,303 --> 00:11:49,119 ‫Whereas if I am using delete 185 00:11:49,631 --> 00:11:52,447 ‫It will delete the position of that element 186 00:11:52,703 --> 00:11:53,983 ‫So for example 187 00:11:54,495 --> 00:11:55,519 ‫if we write 188 00:11:55,775 --> 00:11:56,543 ‫Dell 189 00:11:56,799 --> 00:11:58,591 ‫,L4 190 00:11:59,615 --> 00:12:05,759 ‫And then I have to specify the location so if I write zero that means the first location 191 00:12:06,271 --> 00:12:08,575 ‫Will be deleted 192 00:12:09,343 --> 00:12:10,879 ‫we'll run L4 193 00:12:11,647 --> 00:12:14,463 ‫Can see the ###### is now deleted 194 00:12:14,719 --> 00:12:15,487 ‫We are only 195 00:12:15,999 --> 00:12:19,071 ‫Only 5 7 2 10 are remaining. 196 00:12:20,095 --> 00:12:24,959 ‫Now if you want to know more about less you can write help 197 00:12:25,471 --> 00:12:31,615 ‫Help is a Keyword you can use anywhere you can write help and in bracket 198 00:12:31,871 --> 00:12:34,943 ‫You can write list 199 00:12:35,455 --> 00:12:36,991 ‫if you run this 200 00:12:38,271 --> 00:12:44,159 ‫You will get all the information about list we are not going to discuss all here 201 00:12:44,415 --> 00:12:49,791 ‫and just quick tip if you want to remove your output 202 00:12:50,047 --> 00:12:51,583 ‫Just select the cell 203 00:12:52,351 --> 00:12:58,495 ‫Convert it to low MB and then again convert it to 4 then now your output is ###### 204 00:12:59,519 --> 00:13:04,127 ‫If you have some large output you can you probably want to do this 205 00:13:04,895 --> 00:13:09,503 ‫Now let's move on to tuples, tuples is another data type 206 00:13:10,527 --> 00:13:11,807 ‫Provided by Python 207 00:13:18,975 --> 00:13:21,535 ‫So tuples are just like list 208 00:13:21,791 --> 00:13:25,119 ‫Except that they cannot be modified once created 209 00:13:26,399 --> 00:13:27,935 ‫That's why we call them 210 00:13:28,191 --> 00:13:29,471 ‫Immutable 211 00:13:29,727 --> 00:13:31,775 ‫So tuples are immutable 212 00:13:32,031 --> 00:13:33,311 ‫and a list 213 00:13:33,567 --> 00:13:34,847 ‫Is mutable 214 00:13:36,383 --> 00:13:39,455 ‫So to assign a tuple we use 215 00:13:40,223 --> 00:13:41,247 ‫Parenthesis 216 00:13:41,759 --> 00:13:46,367 ‫So for list we use square bracket for tuples we use 217 00:13:46,879 --> 00:13:48,671 ‫Parenthesis so if you write 218 00:13:48,927 --> 00:13:50,207 ‫P 219 00:13:50,975 --> 00:13:52,255 ‫Equal to 220 00:13:52,511 --> 00:13:53,791 ‫Parenthesis 221 00:13:54,047 --> 00:13:56,095 ‫1, 2. 222 00:14:01,727 --> 00:14:03,519 ‫If you see 223 00:14:03,775 --> 00:14:06,335 ‫When we were out putting the list 224 00:14:06,847 --> 00:14:10,687 ‫There were square bracket at the end and at the start 225 00:14:10,943 --> 00:14:13,247 ‫But for the tuples we have 226 00:14:13,503 --> 00:14:14,527 ‫Parenthesis 227 00:14:15,039 --> 00:14:19,135 ‫And we cannot change the values of this elements 228 00:14:20,671 --> 00:14:21,695 ‫So 229 00:14:21,951 --> 00:14:22,975 ‫Just you try 230 00:14:23,487 --> 00:14:28,095 ‫If you want to change the value of first element we can write P1 231 00:14:29,887 --> 00:14:31,935 ‫Then square bracket 0 232 00:14:33,471 --> 00:14:35,007 ‫Equal to 5 233 00:14:35,263 --> 00:14:37,567 ‫Since this is a tuple 234 00:14:37,823 --> 00:14:43,199 ‫Will get an error while running this you can see the error is 235 00:14:43,455 --> 00:14:49,599 ‫Tuple object does not support item assignment you cannot change the value of tuple once created. 236 00:14:50,367 --> 00:14:54,463 ‫To get the type of the ####### type T1 237 00:14:54,975 --> 00:14:57,023 ‫You can see the type is tuple. 238 00:14:58,815 --> 00:15:03,167 ‫There are very limited use cases of tuples and we will hardly use tuples 239 00:15:03,935 --> 00:15:07,007 ‫In our analysis let's move on to 240 00:15:07,263 --> 00:15:09,567 ‫The next data type which is dictionary. 241 00:15:15,711 --> 00:15:18,271 ‫Dictionaries are also like list 242 00:15:18,783 --> 00:15:22,111 ‫Except that each element is a key value pair 243 00:15:22,879 --> 00:15:28,767 ‫And the syntax for assigning dictionaries is using curly brackets in a list 244 00:15:29,279 --> 00:15:35,423 ‫We use the square bracket in tuple we use parentheses in dictionaries will 245 00:15:35,679 --> 00:15:36,959 ‫Curly bracket. 246 00:15:37,727 --> 00:15:38,239 ‫So 247 00:15:38,495 --> 00:15:39,263 ‫in our list 248 00:15:40,543 --> 00:15:46,687 ‫There are indexes starting from 0 1 2 3 4 here you can say that you are 249 00:15:46,943 --> 00:15:52,831 ‫You are assigning this indexes on your own so for each element you have to assign an index 250 00:15:53,087 --> 00:15:54,367 ‫Which we call a key. 251 00:15:54,879 --> 00:16:01,023 ‫And the element is called as value that's why we define dictionaries as a collection of key-value 252 00:16:01,279 --> 00:16:02,303 ‫Pairs. 253 00:16:02,815 --> 00:16:06,655 ‫So to assign a variable B1 254 00:16:08,447 --> 00:16:11,519 ‫Which is the dictionary will write equal to curly bracket 255 00:16:12,287 --> 00:16:16,639 ‫Now here first we have to write the key 256 00:16:16,895 --> 00:16:17,663 ‫###### 257 00:16:18,431 --> 00:16:22,015 ‫And then get colon and the value of this key 258 00:16:22,527 --> 00:16:24,319 ‫Which is one 259 00:16:25,599 --> 00:16:27,135 ‫Comma 260 00:16:27,391 --> 00:16:28,159 ‫key 2 261 00:16:32,767 --> 00:16:34,303 ‫So in a list 262 00:16:34,815 --> 00:16:40,959 ‫There were indexes 01234 this T1 T2 T3 and just like indexes. 263 00:16:48,895 --> 00:16:50,687 ‫if we run this 264 00:16:52,735 --> 00:16:56,575 ‫we'll write ###### run this you can see 265 00:16:58,367 --> 00:17:00,927 ‫In this we were only getting the values 266 00:17:01,183 --> 00:17:03,743 ‫And here we are getting first the keys 267 00:17:03,999 --> 00:17:05,279 ‫And then the value. 268 00:17:06,303 --> 00:17:07,839 ‫So if you want 269 00:17:08,351 --> 00:17:14,239 ‫You can see that type of this D1 write type P1 270 00:17:16,031 --> 00:17:16,799 ‫The type is 271 00:17:17,055 --> 00:17:17,823 ‫Dictionary. 272 00:17:18,847 --> 00:17:19,615 ‫Now 273 00:17:19,871 --> 00:17:23,455 ‫If I want to Grab the first value I will write D1 274 00:17:25,503 --> 00:17:27,039 ‫And in square bracket 275 00:17:27,295 --> 00:17:29,087 ‫I will write keyone. 276 00:17:33,439 --> 00:17:34,719 ‫if we run this 277 00:17:35,743 --> 00:17:37,023 ‫You can see 278 00:17:38,047 --> 00:17:39,071 ‫for the key 279 00:17:39,327 --> 00:17:41,887 ‫key1 we have a value of 1 280 00:17:42,143 --> 00:17:42,911 ‫In a list 281 00:17:43,679 --> 00:17:48,031 ‫We were using directly using the indexes such as 0 1 2 3 4 282 00:17:48,799 --> 00:17:51,359 ‫In dictionaries we have to use this keys 283 00:17:51,615 --> 00:17:53,919 ‫To get the value of that pair. 284 00:17:56,223 --> 00:17:58,271 ‫So 285 00:17:58,783 --> 00:18:04,671 ‫if I try to write like this D1 square bracket 0 that is the first element I will get an error 286 00:18:05,439 --> 00:18:10,047 ‫I always have to refer this value using the key of this value. 287 00:18:15,167 --> 00:18:17,215 ‫So Python also supports 288 00:18:17,471 --> 00:18:19,775 ‫Conditional statement such as 289 00:18:20,031 --> 00:18:22,335 ‫If, else or else if 290 00:18:22,591 --> 00:18:24,639 ‫It also support 291 00:18:25,151 --> 00:18:27,967 ‫Loops such as for loop and while loop 292 00:18:28,479 --> 00:18:30,527 ‫We are not going to discuss this here 293 00:18:30,783 --> 00:18:32,575 ‫If you want you can explore 294 00:18:32,831 --> 00:18:33,343 ‫This 295 00:18:33,599 --> 00:18:34,623 ‫On your own 296 00:18:35,647 --> 00:18:37,439 ‫If needed we will discuss it 297 00:18:38,207 --> 00:18:39,743 ‫In our upcoming lectures.
