1 00:00:00,990 --> 00:00:08,490 ‫So we have started this reporter's notebook from an academic and then we go to now to create a new notebook. 2 00:00:08,940 --> 00:00:14,220 ‫Click on this new button in the top right corner and click on Python three. 3 00:00:15,720 --> 00:00:18,600 ‫This will open a new notebook in the new tab. 4 00:00:24,220 --> 00:00:31,450 ‫This is the forage, a notebook interface and notebook you write and run your codes and small segments, 5 00:00:32,110 --> 00:00:34,570 ‫and this segments are called cells. 6 00:00:36,560 --> 00:00:44,180 ‫Apart from executing your code, the cells can also be used for commenting, and it is really helpful 7 00:00:45,020 --> 00:00:51,170 ‫to make your code readable and easy to follow to write the code. 8 00:00:51,200 --> 00:00:57,800 ‫You just have to click on this cell and, for example, to actual numbers, you can just write 2+2. 9 00:00:57,890 --> 00:01:02,210 ‫So this is where you will write your codes to execute this code. 10 00:01:02,360 --> 00:01:04,460 ‫Just press control. 11 00:01:04,460 --> 00:01:04,970 ‫Enter. 12 00:01:09,690 --> 00:01:15,220 ‫So you can write your codes in the cell and you will get the output just below. 13 00:01:16,290 --> 00:01:23,310 ‫You can see what input we have and and for all the outputs we have out 14 00:01:26,040 --> 00:01:28,620 ‫on the top, you can see different menu items. 15 00:01:30,920 --> 00:01:42,590 ‫File contains general options like saving, printing or renaming added contents related options like 16 00:01:42,590 --> 00:01:46,040 ‫cut cell copy, cell based cell or delete cell. 17 00:01:48,830 --> 00:01:56,570 ‫View contains interface related options and inserts contents option to insert new cells. 18 00:02:00,520 --> 00:02:08,620 ‫Since menu item contains execution related options, and as the name suggests, help contains references 19 00:02:08,620 --> 00:02:11,620 ‫and manuals on how to use your partner notebook. 20 00:02:12,430 --> 00:02:15,430 ‫You can also find a list of shortcuts from your. 21 00:02:22,920 --> 00:02:28,620 ‫Now, most of the options we are going to use are also available in the form of buttons. 22 00:02:29,670 --> 00:02:37,860 ‫So suppose if I want to rename this file as lecture one, I will do that by clicking on this file name 23 00:02:37,860 --> 00:02:41,130 ‫and title and just rename it to lecture one. 24 00:02:49,310 --> 00:02:52,430 ‫To save this file, we can click on the Save button. 25 00:02:55,390 --> 00:02:58,800 ‫It will automatically save your file and your default directory. 26 00:03:01,350 --> 00:03:06,900 ‫And next time you open Jupyter Notebook, you will be able to see this file in the ordinary directly 27 00:03:07,350 --> 00:03:09,270 ‫from Jupyter Notebook homepage. 28 00:03:12,200 --> 00:03:15,200 ‫There are also buttons to cut copy paste. 29 00:03:17,570 --> 00:03:20,720 ‫We also have a button to execute our codes. 30 00:03:21,530 --> 00:03:28,850 ‫So again, if I if I click on my cell and click on run, it will execute the same. 31 00:03:31,660 --> 00:03:35,680 ‫Now you can see this drop down menu is code. 32 00:03:36,850 --> 00:03:40,630 ‫This means the cell we have selected, it's containing a code. 33 00:03:41,830 --> 00:03:47,260 ‫If I wanted to contain a comment, I can change it to either raw or markdown formatting. 34 00:03:49,420 --> 00:03:57,460 ‫If I change it to download Raw, our Python kernel will note that the sale the content of this particular 35 00:03:57,460 --> 00:04:01,480 ‫cell is just for commenting and it will not execute it. 36 00:04:02,680 --> 00:04:09,910 ‫The presence of this feature make over code more readable and understandable, so I will go ahead and 37 00:04:09,910 --> 00:04:14,590 ‫change the format of this said it to me, which is modern. 38 00:04:15,520 --> 00:04:21,340 ‫You can see when I'm changing my cell to mark down, the input symbol goes away. 39 00:04:21,940 --> 00:04:28,240 ‫There is no input symbol here and what symbols are present on the in the front of codes. 40 00:04:29,590 --> 00:04:33,990 ‫I can write anything in this empty cell, and Python reads this as a command. 41 00:04:34,510 --> 00:04:36,220 ‫So let's go ahead and write. 42 00:04:36,370 --> 00:04:37,630 ‫This is an empty cell. 43 00:04:47,210 --> 00:04:55,820 ‫Meltdown cells also supports modern formatting, so if I want to give her name, I can use bone symbol. 44 00:04:58,550 --> 00:05:00,800 ‫So will give up hiding, hiding one. 45 00:05:06,610 --> 00:05:07,750 ‫If I execute this. 46 00:05:11,590 --> 00:05:15,850 ‫You can see, since I use bomb symbol in front of the siding one. 47 00:05:16,570 --> 00:05:19,990 ‫The fine for hiding one is in the hiding format. 48 00:05:22,740 --> 00:05:27,480 ‫We can also use multiple bones symbols to change this size. 49 00:05:27,870 --> 00:05:31,110 ‫So if I use those symbols for heading to. 50 00:05:37,650 --> 00:05:42,120 ‫You can see heading to is slightly smaller than heading one. 51 00:05:42,360 --> 00:05:48,690 ‫You can also use three, four, five or six bond symbol to change the size of the settings. 52 00:05:52,880 --> 00:05:57,560 ‫You can also use as strict symbols to give bullets. 53 00:05:59,390 --> 00:06:10,400 ‫So if I write a strike, if I write bullet point, this strict symbol will be directly converted into 54 00:06:10,400 --> 00:06:10,890 ‫a bullet. 55 00:06:10,930 --> 00:06:11,270 ‫So. 56 00:06:20,740 --> 00:06:26,410 ‫If I execute it, you can see the stick symbols are now converted into bullets. 57 00:06:26,590 --> 00:06:30,340 ‫And we are seeing all our points and proper bullet points. 58 00:06:35,870 --> 00:06:38,680 ‫There are multiple features for editing Mondo. 59 00:06:39,110 --> 00:06:44,250 ‫You can Google it, and if you want, you can learn more about this formatting. 60 00:06:45,680 --> 00:06:53,060 ‫Again, note that Mondo not just for commenting your python is not actually executing this sentence. 61 00:06:55,700 --> 00:06:57,410 ‫The next cell format is raw. 62 00:06:58,130 --> 00:07:02,300 ‫Raw is similar to markdown, but it does not support formatting. 63 00:07:03,590 --> 00:07:05,150 ‫So if you convert it to raw. 64 00:07:08,860 --> 00:07:11,670 ‫If you converted to drop, it will remain like this. 65 00:07:12,210 --> 00:07:17,000 ‫You will not be able to get formatting out of this cells again. 66 00:07:17,020 --> 00:07:21,000 ‫Roy's also for commenting and Python will not execute it. 67 00:07:23,670 --> 00:07:31,870 ‫Code is the format in which we write our codes, and Python will only execute cells that are marked 68 00:07:31,920 --> 00:07:32,700 ‫death squads. 69 00:07:34,470 --> 00:07:38,370 ‫You can see the format for this cell is scored. 70 00:07:39,450 --> 00:07:42,090 ‫Therefore, I can use my codes in this cell. 71 00:07:42,750 --> 00:07:53,340 ‫So if I write 2+2, I can execute it either by clicking this run button or by pressing the shortcut 72 00:07:53,340 --> 00:07:56,730 ‫key that is control, enter or not. 73 00:07:57,420 --> 00:07:59,280 ‫I will click on this red button. 74 00:08:01,680 --> 00:08:09,030 ‫Similarly, if I write five plus three, this time, I will lose control under control, and there is 75 00:08:09,030 --> 00:08:12,270 ‫no shortcut to run the Senate to execute the Senate. 76 00:08:15,560 --> 00:08:21,630 ‫But most of the time, we also want to enter a blank cell, been in this cell. 77 00:08:23,180 --> 00:08:30,320 ‫In that case, I can use oil and instead of controlling the alternator, will execute the cell. 78 00:08:31,120 --> 00:08:33,290 ‫Also, it will insert a blank cell. 79 00:08:34,630 --> 00:08:44,170 ‫Just below this cell, so for all alternator, it has executed the sale and it has inserted a new sale, 80 00:08:44,200 --> 00:08:46,950 ‫a new blank sell just below this.
