1 00:00:00,880 --> 00:00:02,980 Welcome to today's bonus example. 2 00:00:02,980 --> 00:00:07,990 We're going to create a daily journal app which behaves like this. 3 00:00:07,990 --> 00:00:10,600 So let me demonstrate you the output of the program. 4 00:00:12,520 --> 00:00:15,820 The program first asks the user to enter today's date. 5 00:00:15,820 --> 00:00:21,070 So let's enter 2022 and ten, maybe 20. 6 00:00:22,900 --> 00:00:29,890 You press enter the program, asks you again to rate your moods the mood you had today from 1 to 10. 7 00:00:31,240 --> 00:00:36,100 Let's answer eight, for example, and then you write the thoughts of the day. 8 00:00:38,630 --> 00:00:41,790 So let's write something like it was a good day in general. 9 00:00:41,810 --> 00:00:43,050 No big events happened. 10 00:00:43,070 --> 00:00:44,000 Press enter. 11 00:00:44,630 --> 00:00:45,320 That's it. 12 00:00:45,350 --> 00:00:51,950 Now, if you go to the Journal Directory, which I had created earlier, so you need to create this 13 00:00:51,950 --> 00:00:53,120 directory manually. 14 00:00:53,360 --> 00:00:57,440 And then inside this, a file was generated by Python. 15 00:00:57,590 --> 00:01:00,140 So that's the contents of our. 16 00:01:01,220 --> 00:01:02,140 Program. 17 00:01:02,720 --> 00:01:08,600 So every new day that you execute the program, it will create a new file. 18 00:01:09,800 --> 00:01:17,990 So ten days, ten files, and each file is going to contain the date of the day as a file name. 19 00:01:19,210 --> 00:01:20,600 Yeah, let's write the program. 20 00:01:22,130 --> 00:01:25,230 So, first of all, we want to ask the user to enter today's date. 21 00:01:25,250 --> 00:01:29,090 So we need an input function for that with the string. 22 00:01:32,200 --> 00:01:35,620 Next, we ask the user to rate their mood. 23 00:01:35,620 --> 00:01:37,630 So another input function. 24 00:01:38,380 --> 00:01:41,110 So we've got two variables data and mood. 25 00:01:48,770 --> 00:01:53,480 Then we ask the user again to just write down their thoughts. 26 00:01:53,480 --> 00:01:55,640 So yet another input function. 27 00:01:56,450 --> 00:02:01,850 I'm writing here, I'm having a backslash and to create a break line. 28 00:02:01,850 --> 00:02:09,380 You saw that when I entered the inputs here as a user, the input was written in the next line. 29 00:02:09,380 --> 00:02:12,830 So a break line was created by this backslash. 30 00:02:12,830 --> 00:02:19,310 N By the way, this output was executed from. 31 00:02:20,250 --> 00:02:24,480 A script which is somewhere here, but I don't want to show the script to you in the beginning. 32 00:02:25,380 --> 00:02:27,990 So now we want to recreate that program again. 33 00:02:29,250 --> 00:02:36,720 Once we get the inputs, then we want to create a file using that as a name for the file. 34 00:02:36,750 --> 00:02:40,110 So let's write with open. 35 00:02:42,180 --> 00:02:43,020 Date. 36 00:02:43,650 --> 00:02:47,940 So the file, the actual file path would be something like 37 00:02:51,030 --> 00:02:52,800 dot, dot, slash. 38 00:02:54,180 --> 00:02:54,940 Journal. 39 00:02:55,230 --> 00:02:57,360 Slash and then the date 40 00:03:00,420 --> 00:03:05,010 and close and curly quotes and this would be an F string. 41 00:03:05,010 --> 00:03:08,760 So let me close the string here and make it an F string. 42 00:03:09,180 --> 00:03:17,310 And these two dots, as you know, are when my python file is inside an inner directory. 43 00:03:17,310 --> 00:03:19,200 In my case, it's inside bonus. 44 00:03:19,200 --> 00:03:26,430 So bonus and journal are in the same directory, so the file has to go up one level with these dots 45 00:03:26,430 --> 00:03:31,710 and then points to journal and then date dot text. 46 00:03:33,480 --> 00:03:38,220 So this file will be created in right mode. 47 00:03:41,470 --> 00:03:44,380 And in the next line, which is indented. 48 00:03:46,060 --> 00:03:46,760 We say, fine. 49 00:03:46,780 --> 00:03:47,800 That's right. 50 00:03:48,880 --> 00:03:50,800 What do we write here? 51 00:03:52,240 --> 00:03:57,280 So the content would have the rates on top. 52 00:03:57,580 --> 00:04:01,330 So that means this would be the mood. 53 00:04:05,170 --> 00:04:08,340 Then we don't close the file we write. 54 00:04:10,350 --> 00:04:12,690 The journal in the file. 55 00:04:13,610 --> 00:04:15,740 All the text or whatever you call it. 56 00:04:16,160 --> 00:04:18,200 So the thoughts of the user. 57 00:04:19,899 --> 00:04:24,790 Let's rename it to false actually does make more sense. 58 00:04:28,130 --> 00:04:36,200 And yeah, I'll run the script now, so make sure that a journal directory exists and it reflects that. 59 00:04:37,110 --> 00:04:37,820 Path there. 60 00:04:37,950 --> 00:04:38,550 Journal. 61 00:04:38,550 --> 00:04:39,420 Journal. 62 00:04:39,450 --> 00:04:43,680 I'll delete the existing file and run the script. 63 00:04:45,330 --> 00:04:49,740 Today's date 2022 2010. 64 00:04:49,860 --> 00:04:50,610 Enter. 65 00:04:50,910 --> 00:04:51,740 How do you rate? 66 00:04:51,750 --> 00:04:52,920 Let's try seven. 67 00:04:55,050 --> 00:04:57,330 Nice day in general. 68 00:04:59,190 --> 00:05:00,300 It was fun. 69 00:05:00,690 --> 00:05:01,680 Press enter. 70 00:05:04,000 --> 00:05:05,920 And let's check journal. 71 00:05:06,430 --> 00:05:08,440 So that's the outputs. 72 00:05:08,710 --> 00:05:09,880 We're close. 73 00:05:09,910 --> 00:05:14,890 Seven is the rate and is not so well formatted. 74 00:05:14,890 --> 00:05:20,020 So we want to have like one two break lines between these two. 75 00:05:20,320 --> 00:05:26,710 So in that case, we want to go back to the Python file. 76 00:05:28,110 --> 00:05:33,990 And after Moody's, which is seven, seven, is a string. 77 00:05:34,350 --> 00:05:37,260 So it comes as a string from the input function. 78 00:05:38,430 --> 00:05:44,010 So basically, mood is a string. 79 00:05:44,190 --> 00:05:47,760 And if you do mood. 80 00:05:51,680 --> 00:05:54,110 Plus backslash. 81 00:05:54,110 --> 00:06:04,550 GN You get seven backslash N But this is the output in the command line, so if you use a print function. 82 00:06:07,080 --> 00:06:09,810 Backslash, and it's printed out as an actual brake line. 83 00:06:10,560 --> 00:06:16,560 So now we have a brick line here when you just call the expression like that, without printing in the 84 00:06:16,560 --> 00:06:20,820 python console, you always get the row, the row string like that. 85 00:06:23,950 --> 00:06:29,550 So we can use that expression or we can also do two times that. 86 00:06:29,560 --> 00:06:40,570 So we have to break lines one, two, so let's say plus two times backslash ends. 87 00:06:40,960 --> 00:06:46,210 So that is the equivalent of if you set plus backslash n. 88 00:06:48,450 --> 00:06:49,920 Plus another backslash. 89 00:06:49,920 --> 00:06:56,520 N And so you get the same behavior you see here and there. 90 00:06:56,520 --> 00:07:07,350 We have these break lines so that we can try the code again, this time with another date going to 21. 91 00:07:08,630 --> 00:07:10,510 Ten Press enter. 92 00:07:10,610 --> 00:07:11,880 How do you rate?
