WEBVTT 00:01.910 --> 00:07.440 On in this particular session, we would be learning about Ogg's and GWM. 00:08.270 --> 00:15.680 So first of all, before completely digging into what these are, let us try to understand what is the 00:15.680 --> 00:17.080 actual need for this. 00:17.960 --> 00:23.590 So let me simply create a function C. diff. 00:24.970 --> 00:34.180 This is my function name, which is my phone, and in my function, I want to give two arguments the 00:34.180 --> 00:35.020 economy. 00:35.890 --> 00:39.730 And as a result, I want to read on. 00:42.310 --> 00:43.240 There's some. 00:45.210 --> 00:51.090 Of the values which I've got as my argument, so let's say a form of. 00:54.320 --> 00:57.890 So let me run this particular function, so my. 01:02.540 --> 01:08.390 And let us say, I want to get us out of a hundred and fifty. 01:09.670 --> 01:13.050 So on running this, I get 150 as a result. 01:14.700 --> 01:21.720 Now, let us try another scenario now in this particular case, let us say I want to have. 01:23.140 --> 01:24.730 Some of these values only. 01:25.660 --> 01:28.160 That is one difference which I want to have you. 01:28.570 --> 01:37.740 I want to have a default value as zero so that in case I want to have more numbers, I want to add more 01:37.750 --> 01:38.180 numbers. 01:38.200 --> 01:44.470 I'm not sure how many numbers I will have, but I know that the maximum number of values which I will 01:44.470 --> 01:45.690 be getting is five. 01:45.940 --> 01:48.410 I just want to do a song for them. 01:49.120 --> 01:54.040 So let us copy this entire thing again and create this function again. 01:54.310 --> 01:57.820 But this time I want to given more value, Cissie. 01:58.970 --> 02:00.140 Dean and. 02:01.810 --> 02:05.220 Now, I can do the same thing here. 02:07.400 --> 02:16.070 And I can return the news now, it's fine if I have five values in hand and I run this, I will get 02:16.070 --> 02:16.570 the result. 02:17.270 --> 02:20.280 But let's say I'm not sure how many values I have. 02:20.540 --> 02:23.830 So what I can do is I can put a default value as. 02:29.790 --> 02:34.140 And in that case, if I only have to use. 02:35.440 --> 02:39.790 This would still work, but if I have just one value. 02:41.160 --> 02:42.450 It was minister. 02:43.970 --> 02:56.000 So let us run this again so far that what I can do is I can again give a default value to all of these. 02:57.570 --> 03:04.710 This is perfectly fine if I have an upper limit to the number of values which I will be having, but 03:04.920 --> 03:12.690 in case I might have state, instead of these five values, I can have a hundred values or thousand 03:12.690 --> 03:22.530 values, then it would be difficult for me to track how many variables I have created and to keep a 03:22.530 --> 03:27.660 note of each and every variable and write the entire piece of code again and again. 03:29.010 --> 03:33.060 So this is where the need for are coming. 03:34.920 --> 03:40.050 So what I can do here is I can create another function. 03:42.130 --> 03:43.180 In the same way. 03:44.650 --> 03:50.470 And in this function, I can give the initial values as default if I want if I don't want to give a 03:50.470 --> 03:54.060 default value and I wanted to throw in it, or I can do that also. 03:54.310 --> 03:57.280 But let us I just want to give the two values as default. 03:59.070 --> 04:07.250 And I want to give the value, which is I'm not sure I know that I will be getting at least two values. 04:07.530 --> 04:10.650 So let me bring these also. 04:13.460 --> 04:20.300 I am not sure if I will be getting more than two values or I'm just I just know that the minimum number 04:20.300 --> 04:21.320 of values would be, too. 04:21.500 --> 04:22.730 So I'm ready for those. 04:22.910 --> 04:28.980 And whatever extra values I'll have, I'll keep them as a part of star parks. 04:29.630 --> 04:33.920 Now, this is just a name which we have provided. 04:34.130 --> 04:37.820 We can have any other new also instead of OG's. 04:37.820 --> 04:48.320 I can give name or names or X, Y, Z, anything instead of ours. 04:48.650 --> 04:54.320 But by default, just to make it a little simplistic in nature, we just give it to you. 04:55.130 --> 05:00.830 And instead of returning some of this, what I can do is I can simply return to some of this. 05:02.170 --> 05:02.830 Plus. 05:04.830 --> 05:05.670 The SAML. 05:06.840 --> 05:07.420 Thanks. 05:09.030 --> 05:13.090 So here this ogg's is present in form of a couple. 05:13.350 --> 05:19.620 So it will basically some values inside this of some key values of this under this. 05:21.520 --> 05:32.110 So here we have the desire and in case we have more number of values, it can add those also and it 05:32.110 --> 05:35.890 could be any number of values and it will be judged on the result accordingly. 05:38.000 --> 05:39.800 Another thing to note here is. 05:41.490 --> 05:44.820 The minimum number of values which it is expecting. 05:46.080 --> 05:46.620 It's to. 05:49.100 --> 05:53.200 Because we have already said that it will be getting in the. 05:54.640 --> 06:01.210 So if we are not sure that the minimum number of values will be true, then what we can do is we can 06:01.210 --> 06:02.030 remove these. 06:02.890 --> 06:07.280 So what will happen is let's say we have just one value and we don't have other values. 06:07.720 --> 06:14.540 So in that case, if we done this, if you give us an error because it needs oppositional argument. 06:15.430 --> 06:22.060 So what we can do is instead of this, we can simply say we don't want this value. 06:22.060 --> 06:23.790 We want just one value a. 06:24.940 --> 06:33.880 And we don't want this additional value here, so based on this, it will walk perfectly fine. 06:34.510 --> 06:36.320 So it is not a trivial in nature. 06:36.340 --> 06:45.700 So instead of having this complex structure, we can simply have only Ogg's present and then we don't 06:45.700 --> 06:46.780 have any restriction. 06:46.780 --> 06:53.560 We can given one value we can give any number of values, any number of values could be given. 06:56.020 --> 06:58.900 And it was just as good as before. 07:01.400 --> 07:03.150 This is about Star. 07:03.920 --> 07:10.140 So this is when we have one type of value, which we are not sure how many values would be present. 07:10.520 --> 07:14.210 So in that case, we will be using start ups. 07:14.630 --> 07:24.170 Now, that is on the that type of method which we have, which is the Blue Ox, which is basically keyword 07:24.170 --> 07:25.030 arguments. 07:25.560 --> 07:27.530 OK, so when we say. 07:28.840 --> 07:30.240 Star OG's. 07:32.430 --> 07:45.390 It does for one of values and always remember the values which are which we are sure we would be providing 07:45.750 --> 07:47.310 would be coming up first. 07:47.580 --> 07:56.940 After that, we will be declaring the start ups and even after that, we will be starting talking about 07:56.940 --> 07:57.820 the KW. 07:58.830 --> 08:05.550 So this is the cynics and this is the order in which we will always be providing the arguments and the 08:05.550 --> 08:06.070 documents. 08:06.660 --> 08:08.520 So this is one thing to be remembered. 08:09.090 --> 08:10.350 So let me to move this. 08:10.800 --> 08:17.370 And he worded argument is given with two stars in front of it. 08:17.820 --> 08:19.470 So this would be AWB. 08:19.820 --> 08:25.170 Again, the state of new ogg's could be replaced by any of the characters or any of those strings would 08:25.170 --> 08:25.310 be. 08:25.320 --> 08:26.250 Hello, hi. 08:26.250 --> 08:31.650 My name, your name, anything like that and all it can be used for. 08:32.990 --> 08:36.200 Multiple values. 08:38.370 --> 08:41.840 That began with the same two a.m. phone from. 08:44.040 --> 08:48.030 OK, now let us see an example of this. 08:49.350 --> 08:56.730 So this gate of new arguments is in a form of a dictionary, so whenever I will be giving this, I will 08:56.730 --> 08:58.640 be giving it in form of a dictionary. 08:58.920 --> 09:03.240 So what I can do is so let me declare a function again. 09:03.240 --> 09:04.100 See this? 09:04.680 --> 09:06.190 And again, my funk. 09:07.080 --> 09:14.820 And in this function, I want to give or let us say I want to give two values, C and B, these are 09:14.820 --> 09:17.570 two default value, which I will be anyhow giving. 09:17.580 --> 09:22.560 So I'm just giving the name in case I want to give any of the traditional values. 09:22.560 --> 09:28.740 Then I can give the start of which is of which may or may not be given. 09:29.130 --> 09:34.770 And after that let's say I have these key worded arguments. 09:36.240 --> 09:44.610 OK, this is what I want to have an interest of this, what I want to do is I want to let us see the 09:44.610 --> 09:51.390 first operation, which I want to do is I just want to print the letter, say the sum of these values. 09:51.390 --> 09:54.130 So I want to print A plus B, OK? 09:54.150 --> 09:55.240 This is what I want to do. 09:56.340 --> 09:57.810 And after that. 09:58.780 --> 10:00.100 I want to check. 10:01.380 --> 10:03.000 If let us say. 10:04.590 --> 10:11.130 I'm just talking about different values, so let's say we are talking about fruit, so let us say I 10:11.130 --> 10:15.750 want to have something like if some fruit. 10:17.180 --> 10:18.410 Is president. 10:22.730 --> 10:30.410 In my key ordered arguments, OK, if in the keyboarder documents, I have some fruit. 10:31.430 --> 10:35.960 Then what I wanted to do is I just want to bring back. 10:43.770 --> 10:46.920 I love to eat. 10:49.030 --> 10:56.530 And then I want to give this in a dictionary form, right, and this has to be sort of, you know, 10:56.830 --> 10:58.550 for my thing, kind of a structure. 10:58.720 --> 11:07.150 So what I can do is I can simply say I love to eat and then I want to have the name of the value which 11:07.150 --> 11:07.530 I want. 11:07.540 --> 11:08.470 I would love to it. 11:08.770 --> 11:10.560 And then I give DOT. 11:16.110 --> 11:18.710 OK, just in mustering you. 11:23.770 --> 11:31.690 And what I love, I love to eat the value from the dictionary, so remember I said that we will be giving 11:31.690 --> 11:35.250 this in form of a key value pair or a dictionary form. 11:35.530 --> 11:38.530 So the dictionary name is KW Elsea. 11:39.100 --> 11:44.410 So KW adds, I'm from the gate was what is my key? 11:45.190 --> 11:53.960 Fruit is the key, which is that OK, so I'm checking for fruit so it will check in the dictionary which 11:53.960 --> 11:58.810 fruit you will you have provided that you like and based on that. 12:00.110 --> 12:01.320 It will give the result. 12:02.210 --> 12:10.670 OK, so we will just try to bring this back if this happens, it's well and good. 12:10.670 --> 12:14.660 If this doesn't happen, then I can see else. 12:19.250 --> 12:20.120 Brent. 12:22.870 --> 12:24.630 I paid. 12:25.820 --> 12:26.180 It's. 12:29.970 --> 12:31.530 So this is the function. 12:32.590 --> 12:35.470 And let me see my fun. 12:36.800 --> 12:43.840 I'm inside this, I want to give the value see twenty three point fifty four, which I want to add, 12:44.470 --> 12:48.560 I don't want to give any arguments so I can completely skip that. 12:48.980 --> 12:53.270 And in include I want to give. 12:54.890 --> 12:55.820 Of Throop. 12:57.250 --> 13:00.460 And the fraud, which I want to give, is saying. 13:01.500 --> 13:06.570 Banana and I have a veggie. 13:07.990 --> 13:09.610 And what would do I like? 13:11.590 --> 13:12.940 Let us say. 13:16.450 --> 13:17.240 Garrett. 13:19.860 --> 13:21.180 So let me run this. 13:22.810 --> 13:30.250 And here we get seventy seven, which is the sum of twenty three and fifty four, and I get I love to 13:30.250 --> 13:35.620 eat bananas, so let us say we didn't have fruit inside this. 13:39.630 --> 13:44.720 And I just simply done this so it would give me a true test, the result. 13:46.060 --> 13:55.860 So I just put that back, so similarly, we can have any number of these values so I can have formed 13:55.870 --> 14:00.210 vegies and like and have chocolate or anything within here. 14:00.220 --> 14:04.960 And based on that, I can give any values and I can have any arguments. 14:04.960 --> 14:06.480 And he wanted arguments. 14:06.490 --> 14:16.690 The only thing we can get off is that it has to be in this particular format that the rebels have to 14:16.690 --> 14:17.800 be forced. 14:18.100 --> 14:23.170 Then the arguments have to be given and followed by the keyword argument. 14:23.620 --> 14:29.410 And based on this, you can simply create any index or anything like that and you can just create any 14:29.770 --> 14:34.230 of your code using this entire syndicate, which has been provided to.
