1 00:00:00,150 --> 00:00:01,160 Hi, welcome back. 2 00:00:01,470 --> 00:00:09,900 In this lecture, we will learn that a type of structure, which is dictionaries dictionary as Python 3 00:00:09,900 --> 00:00:19,230 spelled and baMMing type, this means that dictionaries map case to values all these key value bears 4 00:00:19,470 --> 00:00:22,970 are a useful way to store data and python. 5 00:00:23,010 --> 00:00:26,850 When we use a dictionary, we use curly brackets. 6 00:00:26,880 --> 00:00:37,410 So if we want to create a dictionary with all the names and ages of specific students, it will be the 7 00:00:37,410 --> 00:00:38,040 following. 8 00:00:38,040 --> 00:00:43,260 Students equal Provencal brackets between two single codes. 9 00:00:43,530 --> 00:00:46,530 Samey column 13. 10 00:00:46,710 --> 00:00:50,370 Comma Sara column 14. 11 00:00:51,470 --> 00:00:54,920 Comma Zone Column 16. 12 00:00:55,890 --> 00:01:01,680 Coma Ball Column 15 and close to Carlebach. 13 00:01:04,150 --> 00:01:11,620 And to branches to the dictionary, we will use Python brain function as the following brain between 14 00:01:11,620 --> 00:01:19,210 two entities, the students, this World Brain Students dictionary, the final data structure, data 15 00:01:19,210 --> 00:01:28,870 type and python assets, which are unordered collection data types that is iterable mutable and has 16 00:01:28,870 --> 00:01:36,070 no duplicate or duplicated element to create a system based on you will do add the following you will 17 00:01:36,070 --> 00:01:41,920 obtain to carry Brackett's and Edds items inside it, separated by comma. 18 00:01:42,160 --> 00:01:50,590 And if you have a string digit five elements, you are included inside to double code or two single 19 00:01:50,590 --> 00:01:52,180 codes as you like. 20 00:01:52,420 --> 00:02:01,090 After we execute the self hatred in the same list, but written in a different order, then we write 21 00:02:01,090 --> 00:02:01,390 it. 22 00:02:01,660 --> 00:02:10,630 Then we will assign it to a variable called my underscore set and try to present it using print function 23 00:02:10,930 --> 00:02:11,870 as the following. 24 00:02:12,040 --> 00:02:21,450 So Brent, between two parentheses, my underscore said would return the same set in a different order. 25 00:02:21,540 --> 00:02:28,660 Also, this type of data which is set can be changed into frozen sets or immutable data type as the 26 00:02:28,660 --> 00:02:30,940 following phrase underscore. 27 00:02:30,940 --> 00:02:36,670 My underscore said equal frozen sat between two parentheses. 28 00:02:36,670 --> 00:02:45,090 My underscore said Zambrana phrase underscore my underscore said between two parentheses. 29 00:02:45,160 --> 00:02:48,960 This will bring a frozen version of my set. 30 00:02:49,060 --> 00:02:56,590 We will learn how to convert from one type of data to another as the following. 31 00:02:59,270 --> 00:03:08,600 We will use flawed methods or flawed function to convert integers to flawed and vice versa. 32 00:03:08,630 --> 00:03:21,020 We will use and method or function to convert flow to integers as a all so flawed minus one equals minus 33 00:03:21,020 --> 00:03:28,330 one point, OK, and end ten point four will return ten. 34 00:03:28,970 --> 00:03:36,370 And if we want to know the type of our data we will use to function as the following type. 35 00:03:36,380 --> 00:03:37,190 My end. 36 00:03:38,800 --> 00:03:44,530 We return and untie my flow to a return float and so on. 37 00:03:45,700 --> 00:03:49,390 At this moment, we reach the end of this lecture. 38 00:03:49,810 --> 00:03:53,070 Hope you enjoyed this lecture and get all of that. 39 00:03:53,780 --> 00:03:55,220 Thanks for being here. 40 00:03:55,880 --> 00:03:57,050 Thanks for watching. 41 00:03:57,170 --> 00:03:59,140 See you next with you.
