1 00:00:00,590 --> 00:00:05,250 Hi, welcome back, asked by the media students. 2 00:00:05,770 --> 00:00:15,910 Serious in this lecture, we will discuss two of the requests or questions of our README students. 3 00:00:16,090 --> 00:00:27,010 The first question, right, a program that has a Dictionary of POCs name as KS and their prize as values, 4 00:00:27,280 --> 00:00:34,750 then Brent is the items in the dictionary and assorted orders and prompt the user to enter a name and 5 00:00:34,750 --> 00:00:37,950 check if it is present in the dictionary. 6 00:00:37,960 --> 00:00:44,990 If the name doesn't exist, then ask the user to enter pride and detail in the dictionary. 7 00:00:46,720 --> 00:00:49,590 So let's begin to conclude our program. 8 00:00:50,320 --> 00:01:00,010 Firstly, we will create a dictionary called Batak, which will has or contain book names as gays and 9 00:01:00,310 --> 00:01:08,070 prizes as values, both equal in curly bracket between two parentheses. 10 00:01:08,080 --> 00:01:09,940 We will add the name. 11 00:01:10,270 --> 00:01:20,500 The book names a column five comma B between two parentheses column 10. 12 00:01:20,830 --> 00:01:23,050 Comma between two. 13 00:01:23,050 --> 00:01:26,650 Parentheses C, column 15. 14 00:01:28,380 --> 00:01:40,900 Comma between two parentheses D column to any comma between two parentheses E colon twenty five. 15 00:01:41,070 --> 00:01:45,840 Then we ask the user to enter the name of the book he wants. 16 00:01:46,980 --> 00:01:54,450 So name equal aimbot between two bracket two parentheses and at between two. 17 00:01:54,450 --> 00:01:56,040 But the two parentheses. 18 00:01:56,460 --> 00:02:07,200 You want the book named Space close the second parentheses then if the name of the book is in vogue 19 00:02:07,200 --> 00:02:16,470 DECT so program will birth control flow and will form the next print orders if the name and book underscore 20 00:02:16,470 --> 00:02:27,330 dect dot case method best and if the name of the book isn't invoked so the program will ask for the 21 00:02:27,330 --> 00:02:35,550 price of the the user want else price equal aimbot between two brackets and two parentheses. 22 00:02:35,550 --> 00:02:43,750 What is the price of the book you want and leave space and leave his base before you close the second 23 00:02:43,750 --> 00:02:44,240 parenthesis. 24 00:02:44,310 --> 00:02:52,230 Then the program will add the name and the price of the scifi book by the user into pocket book between 25 00:02:52,230 --> 00:02:56,660 two brackets name Equal Price Finalist. 26 00:02:56,660 --> 00:03:04,710 The book will print book after adding the new book by the user's brain between two them bracket print 27 00:03:04,920 --> 00:03:08,760 in brackets sort of in bracket polka dot items. 28 00:03:09,300 --> 00:03:14,910 Items may close the second bracket, then close the first black. 29 00:03:14,920 --> 00:03:17,850 So let's try to run this program. 30 00:03:17,860 --> 00:03:27,750 The program asking me you want the book named AI so it will print the item we enter in the first so 31 00:03:27,750 --> 00:03:30,090 it will print the dictionary items. 32 00:03:30,090 --> 00:03:33,780 Let's start kernel and clear output. 33 00:03:35,330 --> 00:03:39,090 Yes, and run it again at. 34 00:03:39,650 --> 00:03:51,740 Asking me about the name of the book so I will add Z, which is not an architect, so the program will 35 00:03:51,740 --> 00:03:55,260 ask for the price of the book that I want. 36 00:03:55,490 --> 00:04:06,650 I will add 30 35 since the program finally branched out after adding the last item case and values, 37 00:04:06,650 --> 00:04:09,110 which is Z and thirty five. 38 00:04:10,040 --> 00:04:14,750 The second program we will discuss in this lecture or this video. 39 00:04:15,170 --> 00:04:19,760 Consider a scenario where our son is five ice cream every day. 40 00:04:20,490 --> 00:04:23,390 The price of ice cream is different. 41 00:04:23,540 --> 00:04:29,390 His mother pays the bill to the ice cream vendor at the end of every week. 42 00:04:29,390 --> 00:04:29,880 Right. 43 00:04:29,900 --> 00:04:35,900 I buy some programs that can generate the best for the ice cream and send to his mother. 44 00:04:36,140 --> 00:04:43,820 Firstly, we will create the ice cream class, which contain two attributes daily ice cream and price 45 00:04:44,060 --> 00:04:45,230 class ice cream. 46 00:04:45,890 --> 00:04:57,640 D.F. underscore, underscore and underscore underscore, which is that any method for open bracket itself 47 00:04:57,680 --> 00:05:05,080 and daily ice cream and price bracket and column self-doubt. 48 00:05:05,300 --> 00:05:11,330 Daily ice cream ekwall daily ice cream, self-doubt price, equal price. 49 00:05:11,780 --> 00:05:18,460 We will create another method to calculate the total price of every type of the ice cream. 50 00:05:18,680 --> 00:05:27,210 The total price itself then returns the daily ice cream multiplied by itself, the price. 51 00:05:27,440 --> 00:05:33,350 Suppose we have the quantity and the price of three types of the ice cream. 52 00:05:34,220 --> 00:05:40,790 Ice cream one, equal ice cream three and the five that eat in every day. 53 00:05:41,300 --> 00:05:46,220 And five is about ice ice cream to equal ice cream. 54 00:05:46,400 --> 00:05:52,000 One and seven ice cream three, equal ice cream, one and nine. 55 00:05:52,730 --> 00:06:01,870 Then we will print this object, not total price and end the brain function on the to order in the right 56 00:06:01,920 --> 00:06:02,200 order. 57 00:06:02,210 --> 00:06:03,620 We will collect them. 58 00:06:03,770 --> 00:06:12,880 As you see, after we run this school, we will get thirty one, which is the total cost of the prices 59 00:06:13,070 --> 00:06:16,310 of the ice cream consumed by this kid. 60 00:06:16,700 --> 00:06:25,730 But if we want to calculate the total price of the ice cream that gets consumed and in one week we will 61 00:06:25,730 --> 00:06:32,870 add multiply by seven to the total price to be G.F. total. 62 00:06:33,050 --> 00:06:44,450 But I self return self-doubt daily ice cream multiplied by self-doubt price multiply by seven and run 63 00:06:44,630 --> 00:06:45,440 this good. 64 00:06:45,740 --> 00:06:49,760 We will get two hundred and seventeen dollars. 65 00:06:50,420 --> 00:06:51,400 Thanks for watching. 66 00:06:52,190 --> 00:06:53,900 I hope you get all of that. 67 00:06:54,410 --> 00:06:56,360 See you next with you.
