1 00:00:01,680 --> 00:00:06,689 And this video, you learn how to perform grammar checking with Python. 2 00:00:07,680 --> 00:00:15,810 And we're going to do this using an API called Language Tool API, so we're going to be sending requests 3 00:00:15,810 --> 00:00:19,670 to Vets Rest API in the request. 4 00:00:19,680 --> 00:00:26,340 We will send the text we want to check for grammar and we will return the corrected text back. 5 00:00:26,970 --> 00:00:32,340 This will work through a post through requests, not a gets requests, as we have done so far. 6 00:00:32,940 --> 00:00:34,310 So we've get requests. 7 00:00:34,320 --> 00:00:43,440 You just get some ready made dots on there, but with post requests, you send some data. 8 00:00:43,620 --> 00:00:48,460 In this case, we're going to send some text there and the server will process that. 9 00:00:49,140 --> 00:00:57,480 So this time in this post request scenario, the server has to process our data and do calculations 10 00:00:57,480 --> 00:01:02,010 and then return those data to our clients to our program. 11 00:01:03,030 --> 00:01:13,200 The tool will be using, though again, requests so important quests and then create a response object 12 00:01:13,230 --> 00:01:16,530 requests that post this time not gets. 13 00:01:16,650 --> 00:01:21,930 Previously, we used gets no use post and the URL is the first argument. 14 00:01:21,930 --> 00:01:27,300 So you URL is this will be the URL of this API. 15 00:01:27,600 --> 00:01:37,890 So if you go to a language tool dot org slash HTP Dash API and then you go to default in here, so you're 16 00:01:37,890 --> 00:01:40,080 going to see these. 17 00:01:41,930 --> 00:01:43,970 If you press here, check a text. 18 00:01:53,050 --> 00:01:56,890 You're going to see the parameters I'll return in just a while. 19 00:01:57,820 --> 00:02:04,300 What these parameters mean, but the routes you earl is. 20 00:02:07,350 --> 00:02:08,520 HTP as. 21 00:02:10,340 --> 00:02:15,110 Colin Slash slash API dot language tool. 22 00:02:15,410 --> 00:02:16,580 Dot org. 23 00:02:21,430 --> 00:02:26,530 That's a v two slash v to slash check. 24 00:02:27,640 --> 00:02:33,820 So that's where L is going to go in here, but then we have to pass parameters here. 25 00:02:34,210 --> 00:02:38,740 Unlike in the gets requests here, you have to parse dots all you want to process. 26 00:02:39,100 --> 00:02:41,530 So see here what data we can pass. 27 00:02:41,800 --> 00:02:44,620 We can pass text, for example. 28 00:02:45,400 --> 00:02:48,820 This is the text that we need to send for grammar checking. 29 00:02:49,900 --> 00:02:54,280 All you can pass it as Jason, not as a string. 30 00:02:54,280 --> 00:02:59,500 So in that case, you would pass a delta arguments and then you have language, which is a required 31 00:02:59,500 --> 00:03:02,830 argument and all of the parameters as well. 32 00:03:03,080 --> 00:03:10,000 What language is the only required arguments and also texts if you want to check some actual text? 33 00:03:10,930 --> 00:03:13,280 So how do we give these parameters? 34 00:03:13,300 --> 00:03:16,840 Well, we give them through a dictionary. 35 00:03:17,650 --> 00:03:24,760 So first we creates a dictionary, let's say delta, or use just any valuable you like that would be 36 00:03:25,450 --> 00:03:26,590 equal to this dictionary. 37 00:03:26,860 --> 00:03:28,510 And then here you pass keys. 38 00:03:28,840 --> 00:03:34,150 So text, for example, of this key as to reflects one of the parameters in here. 39 00:03:34,360 --> 00:03:38,410 So text and then you parse the text you want to check. 40 00:03:39,850 --> 00:03:43,600 Let's write something grammatically wrong by purpose. 41 00:03:44,470 --> 00:03:50,540 So let's say this is a nice day. 42 00:03:51,040 --> 00:03:57,250 So I wanted to say this is a nice date, but I did want typo in here and one typo in here. 43 00:03:57,860 --> 00:03:58,340 Mm. 44 00:03:58,360 --> 00:04:03,100 So that's the text key and then a comma, and then you pass more parameters. 45 00:04:03,700 --> 00:04:08,290 Language is a required arguments and it will be equal to. 46 00:04:09,310 --> 00:04:15,430 Well, you can press and but you can also say Alter so that you can get the checking, even if this 47 00:04:15,430 --> 00:04:19,209 is another language for any language that this API supports. 48 00:04:19,779 --> 00:04:25,240 And then once you have defined your dictionary there, then in here you provide data. 49 00:04:25,960 --> 00:04:31,630 That's how it's a parameter of the post requests and that is equal to this variable delta. 50 00:04:31,960 --> 00:04:40,210 So data is equal to delta and then print responds the text and run. 51 00:04:42,530 --> 00:04:43,940 And that's the output. 52 00:04:45,320 --> 00:04:49,550 Let's check the type of this output using a type function. 53 00:04:50,900 --> 00:04:58,610 So wrap that expression inside the type and run and you'll see this is a string. 54 00:05:00,320 --> 00:05:04,400 So first of all, we want to convert this into a dictionary. 55 00:05:05,360 --> 00:05:07,460 Therefore, I'm going to import Jason. 56 00:05:08,590 --> 00:05:19,760 And then what I'll do here is, I'll say results is equal to response dot text, but that will go inside 57 00:05:19,760 --> 00:05:20,420 Jason. 58 00:05:20,420 --> 00:05:21,350 That loads. 59 00:05:23,000 --> 00:05:30,800 So JSON that loads converts a string into a dictionary so that we are able to parse that dictionary 60 00:05:30,800 --> 00:05:31,190 we can. 61 00:05:33,100 --> 00:05:40,090 Extracted items of the dictionary, and we cannot do that if the format is a string because a string 62 00:05:40,090 --> 00:05:48,010 is made of characters and the dictionary is recognized by Python as a more compound, other type which 63 00:05:48,010 --> 00:05:52,180 has items and which are made of keys and values. 64 00:05:52,390 --> 00:05:56,680 So Ron, this oh, let me print out results. 65 00:06:00,630 --> 00:06:09,900 So we've got the same outputs as before, but now this will be a dictionary if I check the type of that. 66 00:06:12,850 --> 00:06:13,750 So it's addiction it. 67 00:06:16,380 --> 00:06:17,700 And I'd like to stop here. 68 00:06:18,090 --> 00:06:20,610 So that is a final output for this video. 69 00:06:20,700 --> 00:06:25,800 No, you know how to parse dictionaries, so how to extract Delta from a dictionary? 70 00:06:26,010 --> 00:06:28,050 Using the dictionary keys. 71 00:06:28,440 --> 00:06:34,530 So depending on the application that you want to make, which contains grammar correction functionality, 72 00:06:34,830 --> 00:06:42,270 you might want to extract different values from the dictionary, so you may extract the suggestion of 73 00:06:42,270 --> 00:06:43,530 the correct word. 74 00:06:43,800 --> 00:06:50,040 And in this dictionary, you also have the information where that word is located in the text. 75 00:06:50,460 --> 00:06:55,110 So you can extract the index of the word that is wrong. 76 00:06:55,410 --> 00:07:01,080 Maybe you create a web and then you show this information as popups on the app. 77 00:07:01,410 --> 00:07:06,030 So I'd like to close this video here and to leave you with this dictionary. 78 00:07:06,180 --> 00:07:09,330 So I'll thank you for following this and I'll see you later.
