1 00:00:00,510 --> 00:00:04,700 Throughout the previous videos, we have been using the request library. 2 00:00:04,710 --> 00:00:06,600 We use it into different ways. 3 00:00:06,600 --> 00:00:14,540 First, we tried to get the content of the Yahoo website and we did that by using the text property 4 00:00:14,550 --> 00:00:15,630 as you see in here. 5 00:00:15,930 --> 00:00:19,020 And then we use the request library. 6 00:00:22,310 --> 00:00:23,900 To get Jason data. 7 00:00:23,900 --> 00:00:27,560 And for that we use the JSON method as you see here. 8 00:00:27,800 --> 00:00:34,310 Now in both those cases, what we got was text data, so non binary daughter. 9 00:00:34,910 --> 00:00:37,790 But how do you get binary data? 10 00:00:37,790 --> 00:00:39,640 So how do you get an image? 11 00:00:39,650 --> 00:00:46,190 How can you download an image with three course library or a zip file from the web or any other file 12 00:00:46,190 --> 00:00:47,870 that is not text? 13 00:00:48,410 --> 00:00:50,570 That's what I'll show you in this video. 14 00:00:51,290 --> 00:00:59,720 So let's go to the browser and perhaps go to a Wikipedia page just to get the link of a file. 15 00:00:59,720 --> 00:01:02,090 For example, let's work on an image file. 16 00:01:02,540 --> 00:01:04,519 So I'll work on this image here. 17 00:01:04,940 --> 00:01:08,650 I will download this image with Python and the request library. 18 00:01:08,660 --> 00:01:16,220 So for that I need to know the URL of the image because each file, each image which you see on websites, 19 00:01:16,220 --> 00:01:22,340 they have a particular URL which locates the image in the server where the website is hosted. 20 00:01:22,370 --> 00:01:27,860 To get that, you are really going to right click over this image and Wikipedia and go to open image 21 00:01:27,860 --> 00:01:35,840 in new tab and that will open the image on your browser and you can copy the URL in the address bar. 22 00:01:36,470 --> 00:01:37,700 So I'll copy that. 23 00:01:38,180 --> 00:01:47,300 And since this is out of the context of our app, I'll just open a Python console and show you the code 24 00:01:47,300 --> 00:01:48,080 in here. 25 00:01:48,500 --> 00:01:53,660 So first I will create a URL variable to store the image in this variable. 26 00:01:55,370 --> 00:01:55,640 Right? 27 00:01:55,640 --> 00:02:00,440 So we have the URL variable containing the string pointing to the image. 28 00:02:00,440 --> 00:02:07,340 So make sure that the image name ends with an extension, an image extension such as jpg. 29 00:02:07,370 --> 00:02:11,750 That means the URL is correctly pointing to that image. 30 00:02:12,230 --> 00:02:15,800 So once I have a URL, then I want to import requests. 31 00:02:17,870 --> 00:02:20,890 Then I'll make a request object. 32 00:02:20,900 --> 00:02:30,380 Or you can also say a response object, actually, because the requests that get method actually gives 33 00:02:30,380 --> 00:02:32,750 you a response of the request. 34 00:02:32,750 --> 00:02:35,900 So it makes more sense to call the variable request. 35 00:02:36,350 --> 00:02:37,910 So here goes the URL. 36 00:02:39,530 --> 00:02:45,590 So we that we have a response rate which doesn't look any, I think, exciting. 37 00:02:45,950 --> 00:02:52,400 But we have this number 200 is an A.P. code, which means the response was successful. 38 00:02:53,310 --> 00:02:59,540 Now, we used to work on the tax property earlier. 39 00:03:00,970 --> 00:03:01,540 Both. 40 00:03:01,540 --> 00:03:06,850 This works when you are loading text data such as web pages. 41 00:03:06,850 --> 00:03:10,930 So web pages or text, but an image is not text. 42 00:03:10,930 --> 00:03:14,500 So what you need to use is a response that content. 43 00:03:16,380 --> 00:03:20,010 So these are points which make up the image. 44 00:03:20,010 --> 00:03:27,120 And in the command line you can not see the actual image, but you see the actual row coat that makes 45 00:03:27,120 --> 00:03:27,900 up the image. 46 00:03:27,930 --> 00:03:33,030 So we need to get that code and write it in a file. 47 00:03:33,060 --> 00:03:36,430 For that we use the open function, which you have learned before. 48 00:03:36,450 --> 00:03:39,150 So with open image dot P and sorry. 49 00:03:39,150 --> 00:03:42,030 JPG, it was a jpg file. 50 00:03:42,720 --> 00:03:46,570 And we need to open this in right binary modes. 51 00:03:46,590 --> 00:03:54,690 So for text files, when we created text files, we used to write just w, but this is a binary file. 52 00:03:54,690 --> 00:03:55,620 It's not a text file. 53 00:03:55,620 --> 00:04:01,530 So we need to write WB as file a column press enter. 54 00:04:01,650 --> 00:04:05,310 We indent here for spaces and then we say file. 55 00:04:05,310 --> 00:04:06,480 So that's variable. 56 00:04:06,870 --> 00:04:08,100 That's right. 57 00:04:08,100 --> 00:04:16,050 And here we write the response that content which points to these data to these numbers. 58 00:04:17,070 --> 00:04:25,140 So with that you press enter, enter again and in the root directory of your project you should see 59 00:04:25,140 --> 00:04:27,230 an image that JPG file. 60 00:04:27,240 --> 00:04:30,270 So let's refresh, let's reload this here. 61 00:04:30,300 --> 00:04:31,020 Here it is. 62 00:04:31,710 --> 00:04:32,760 And that's the image. 63 00:04:34,380 --> 00:04:41,940 So that's how you can download an image using a particular URL, the URL which points to the image. 64 00:04:44,400 --> 00:04:48,060 So that's the code again, request that gets the URL. 65 00:04:48,780 --> 00:04:49,680 And then. 66 00:04:53,060 --> 00:05:01,550 You create an empty file and you populate that file with the contents of the response object and that's 67 00:05:01,550 --> 00:05:01,910 it. 68 00:05:02,600 --> 00:05:08,990 The same technique can be used for other files, so if you have the link to a file which is hosted on 69 00:05:08,990 --> 00:05:15,320 some websites on the cloud anywhere on the web, then you can use basically the same code and use the 70 00:05:15,320 --> 00:05:21,080 same WB mode here to create the file and it will work basically the same. 71 00:05:22,040 --> 00:05:28,310 Of course, if it's a zip file, you should give here the correct extension in the file name with that. 72 00:05:28,340 --> 00:05:29,090 Thanks a lot. 73 00:05:29,120 --> 00:05:29,660 See you later.
