WEBVTT 00:01.080 --> 00:01.890 Hello, everyone. 00:02.190 --> 00:07.980 Now you have the knowledge of basic input, output and mathematical operations. 00:08.250 --> 00:12.960 So let's test your knowledge using these very simple questions. 00:13.620 --> 00:19.050 You can pause your screen and try these questions and follow. 00:19.080 --> 00:21.450 I will be explaining the questions after that. 00:34.960 --> 00:37.300 So I hope you have solved these questions. 00:37.600 --> 00:41.290 Now, let me explain these solutions for these one by one. 00:43.090 --> 00:49.060 So the first question is the two numbers as input and print, the result as below. 00:50.020 --> 00:55.600 So first, we'll see how we can take inputs and then print those. 00:56.080 --> 00:56.710 So what? 00:56.710 --> 01:00.280 Digging in, what you can take and put in any way see X 01:04.240 --> 01:09.070 and we say input and insight, input. 01:09.070 --> 01:13.840 We can give any message so that according to the message, the person can give us input. 01:14.170 --> 01:21.310 So we will say, please enter the first number. 01:23.230 --> 01:25.780 And similarly, we will get this number one. 01:43.750 --> 01:57.520 Now, let's also check the class and the data type of X and Y in Boston, you can run using print defects 01:57.520 --> 01:59.770 also and simply type also. 02:00.250 --> 02:02.230 The board will give you similar results. 02:02.650 --> 02:04.030 So let me run this. 02:06.160 --> 02:07.830 So let's say 24. 02:08.090 --> 02:12.460 And so it tells me that the type of string. 02:12.970 --> 02:14.980 But we are expecting numbers. 02:15.160 --> 02:17.740 So this means we need to type these. 02:17.980 --> 02:21.250 So we will simply say int or float. 02:21.670 --> 02:23.350 So let me see it for now. 02:25.780 --> 02:27.870 So I'm assuming that these are individuals. 02:27.880 --> 02:33.430 So I'm digging into you can dig float also or let me take it as sort of set. 02:41.360 --> 02:42.710 And then run this code. 02:47.330 --> 02:51.180 See, now the glassful, both X and Y is flawed. 02:51.230 --> 02:53.600 So now these will be treated as numbers. 02:55.820 --> 03:05.810 Now we can simply find out the sum difference right after the two numbers so we can easily do that. 03:06.350 --> 03:11.780 So we'll simply say print and in the print statement, we can likely get the result. 03:11.780 --> 03:21.800 You can write different statements or something like X plus Y, and then you give a comma so that you 03:21.800 --> 03:25.340 can write string and numbers simultaneously. 03:25.790 --> 03:28.970 And you can see X plus Y. 03:29.570 --> 03:31.520 So you can see you get the results. 03:33.230 --> 03:38.120 Similarly, you can do the same thing for Dufresne's. 03:44.610 --> 03:45.410 Product. 03:58.670 --> 04:05.780 Result of endangered division, so integer division is named this. 04:16.470 --> 04:17.810 Let's see. 04:20.820 --> 04:22.970 So this is the integer division. 04:23.040 --> 04:25.140 This is the product of these numbers. 04:25.380 --> 04:26.940 This is the difference. 04:27.390 --> 04:28.380 This is the sun. 04:28.680 --> 04:34.560 And you can see all the results are coming in flawed because the other day that I have which we have 04:34.560 --> 04:35.780 given is floated. 04:36.090 --> 04:42.450 If you wanted this to be an integer, you could have simply given the type as a leader, and then it 04:42.450 --> 04:45.390 would have dealt with these numbers as integers. 04:45.390 --> 04:46.760 You can practice that also. 04:46.770 --> 04:48.360 You can try different variants. 04:48.390 --> 04:51.330 What happens if X is in Ægir rise fluid? 04:51.340 --> 04:53.460 What happens when water flows? 04:53.790 --> 04:55.920 What happens when both had integer? 04:56.130 --> 04:57.750 So you can try all these things. 05:01.130 --> 05:07.730 Next is the result of flawed division, so let's also get that very quickly. 05:17.510 --> 05:22.180 This is the floor division now you see we have Banner Integer Division. 05:22.220 --> 05:24.930 That is why we are getting one here. 05:24.980 --> 05:29.630 Whatever the remainder is, it is getting completely ignored while here. 05:30.380 --> 05:33.530 These are coming in a float number. 05:33.980 --> 05:42.460 Then we have the Montello, but we don't know what Madeley operator does is it gives you the remainder. 05:42.470 --> 05:45.260 So let's do that as well. 05:49.810 --> 05:58.410 And let's get this so you can see 22 divided by 12. 06:01.210 --> 06:06.010 It gives us Dayna's remainder as expected. 06:06.430 --> 06:09.370 Now, next is the result of Bellmont. 06:09.400 --> 06:12.130 Now let's see what actually the more does. 06:12.460 --> 06:15.280 We are not aware of that is my function. 06:15.290 --> 06:19.420 So it is a good information for us. 06:19.600 --> 06:21.370 So let's see what more does. 06:37.210 --> 06:46.420 Now, you can see it is giving us that this morning is not a flawed operation. 06:46.990 --> 06:51.260 So this means that there is something which is wrong here. 06:52.510 --> 06:58.600 So let's understand how we can look at the documentation of different functions. 06:59.830 --> 07:05.700 So to see the documentation, you can simply say help and insight help. 07:05.710 --> 07:10.540 You can push and give more whatever function you want to need help on. 07:11.050 --> 07:20.650 So here you see the Morente X, X and Y as input, and then it returns to values to us. 07:20.890 --> 07:23.050 So we will get the results out of work. 07:23.290 --> 07:30.040 One is the divisor and the other one is the remainder. 07:30.040 --> 07:35.710 So you get the both the values which you would have got from these two operations separately. 07:36.040 --> 07:41.470 So the desire to have these two operations, I will be getting them separately when I use the word function. 07:41.800 --> 07:49.570 Now, it is very useful to use this help operation because it allows us to see all the documentation. 07:49.580 --> 07:52.330 So you need not remember everything every time. 07:52.540 --> 07:57.550 So whenever you are facing some kind of problem or you forget how the function works, you can simply 07:57.550 --> 07:58.540 use help there. 07:59.950 --> 08:05.170 So we removed this and took X here and done this. 08:05.470 --> 08:06.820 So you can see the result. 08:07.360 --> 08:13.120 So you get one here and then here, as expected. 08:21.750 --> 08:31.950 Now let's see if we can find the result of this particular function using Mad, not Fabel EBC. 08:32.250 --> 08:33.180 Now, what is this? 08:33.660 --> 08:37.740 Let's see these two operations separately. 08:38.010 --> 08:41.310 So for this, we will actually need three numbers. 08:41.610 --> 08:45.510 So let's input another number or let me just simply 08:48.450 --> 08:49.920 create a number here. 08:52.680 --> 08:55.080 So it needs A, B and C. All three. 08:55.500 --> 09:02.880 So I simply say in the form of the pharmacy is equal to see to form a four comma. 09:04.680 --> 09:12.280 So what this operation does here is it will assign two to a four to be five. 09:12.300 --> 09:23.610 To see this particular operation is as good as saying E is equal to to be equal to four and C equal 09:23.610 --> 09:24.090 to five. 09:25.200 --> 09:30.090 So you can either write it this way or write in this way, this one and the same thing. 09:30.840 --> 09:32.840 This is simple in nature. 09:32.850 --> 09:36.230 It's not taking too many lines also. 09:36.240 --> 09:38.140 So that is why we prefer that. 09:38.160 --> 09:40.920 But it's just completely up to you, which some Dexy. 09:40.920 --> 09:41.490 Wonderful. 09:44.020 --> 09:49.720 Now let's have a look at this and let's bring the results of. 09:54.030 --> 09:56.820 And we will also bring the results for this one as well. 10:00.390 --> 10:02.730 Let's see what is the difference between all of this. 10:03.900 --> 10:05.790 OK, so we need the math also. 10:05.790 --> 10:08.550 So math is a package or a library. 10:08.550 --> 10:13.740 You can say, well, we can find many more functions related to mathematics. 10:14.400 --> 10:16.920 So let's import facts. 10:21.690 --> 10:27.510 So this is how you import a library and then you can use the functions of that library or different 10:27.510 --> 10:29.580 attributes associated with that library. 10:29.580 --> 10:36.450 By simply using this dot operator, you simply write the library name, dot the function you want to 10:36.540 --> 10:37.410 use from it. 10:37.980 --> 10:39.450 So I just run this. 10:40.350 --> 10:45.200 And here Bao is expecting two arguments. 10:45.210 --> 10:46.440 Well, got three. 10:47.760 --> 10:49.950 So let us see how this works. 10:54.080 --> 10:55.550 Again, we will put it into. 10:59.290 --> 10:59.540 Help. 11:00.330 --> 11:01.380 So it takes. 11:02.070 --> 11:04.140 So we need to input base. 11:04.680 --> 11:10.650 And it needs the exponential value to what power we want to take it to. 11:13.440 --> 11:19.240 So here you can see this is one. 11:19.260 --> 11:20.340 How did we get it? 11:20.790 --> 11:23.490 We got it from Italy. 11:24.540 --> 11:27.090 And then we are trying to find the remainder of it. 11:27.930 --> 11:28.280 Right. 11:28.680 --> 11:32.890 So similarly, let's say Italy, Barbie. 11:33.360 --> 11:41.580 And then after that, we can simply get the remainder of it using this. 11:42.750 --> 11:43.550 This is the design. 11:43.920 --> 11:49.110 We did the same thing using two different operators. 11:49.110 --> 11:57.060 We can use the double star for the finding of the father. 11:57.420 --> 12:00.990 And also we can use my daughter Bella for the same operation. 12:01.200 --> 12:02.250 You can do it both ways. 12:05.370 --> 12:14.400 Next is rounding up a number to the nearest 20 thousand and the next multiple of this particular number. 12:16.200 --> 12:20.280 So these are two different things which we want to achieve now. 12:20.790 --> 12:27.810 One important thing is that when you want to try and round up a number, you can simply do that to a 12:27.810 --> 12:29.370 particular number of digits. 12:30.000 --> 12:33.890 So it is simple when you want to do it for a particular number of digits. 12:33.930 --> 12:37.140 So let's have a look at the round function. 12:40.340 --> 12:44.160 See, so that function gives us. 12:44.180 --> 12:49.850 It simply takes the number and it takes the number of digits you want to round the number do. 12:50.210 --> 12:52.370 So let's try this out. 12:52.820 --> 12:59.770 So we see a round and we give let's see, one, five, six, seven, some. 13:00.020 --> 13:01.130 What particular number? 13:01.400 --> 13:02.420 Let's do it this way. 13:02.630 --> 13:04.850 And we say let's save two. 13:04.970 --> 13:06.110 Let's see what happens. 13:08.060 --> 13:11.480 It doesn't do anything because here there are two numbers. 13:11.810 --> 13:12.980 Let's make it four. 13:17.250 --> 13:19.030 Now, what is happening? 13:19.050 --> 13:20.310 Nothing is happening here. 13:20.670 --> 13:23.850 So there is some problem with the direction. 13:24.270 --> 13:27.810 So let's put it out here and make it a floating point number. 13:28.110 --> 13:30.330 So I say two, three, four, five, six. 13:30.750 --> 13:32.790 I think a lot of numbers in front of it. 13:33.180 --> 13:35.550 Now let's do it as one. 13:36.540 --> 13:42.270 So it rounds it up to one decimal point. 13:43.680 --> 13:48.300 The next Big Three, it will rounded up to three decimal points. 13:48.930 --> 13:51.300 Now let's put minus three here in stack. 13:52.890 --> 13:57.060 So when we say minus three, it rounds up in the other direction. 13:57.360 --> 14:02.640 So we do not want to do it in a positive direction, but we want to do it in the negative direction. 14:02.970 --> 14:08.250 So we don't want to round up the best moves, but we actually want to round up the numbers. 14:09.450 --> 14:16.530 OK, so we want to rounded to the nearest 20000. 14:19.260 --> 14:21.090 So let's make it minus four. 14:23.380 --> 14:26.520 Well, that is something which we did not want. 14:27.510 --> 14:30.650 What is happening here is we have sixty seven hundred. 14:31.050 --> 14:41.220 So the nearest 20000 will be one five two oh one five. 14:43.040 --> 14:43.970 Twenty thousand. 14:44.360 --> 14:53.030 So this is thousand, so this is fifty six thousand, so the nearest twenty thousand would be one six 14:53.030 --> 14:53.660 seven zero. 14:53.690 --> 14:56.420 So let's complicate this number a little bit. 14:57.320 --> 14:59.190 Let's use some other numbers. 15:03.890 --> 15:08.960 So let's take it one by one, maybe. 15:10.220 --> 15:12.200 So this number. 15:13.130 --> 15:14.600 Let's take another number. 15:14.610 --> 15:16.100 Let's pick three numbers here. 15:42.650 --> 15:52.580 So the nearest 20 thousand to eighty one thousand will be 80000, the nearest 20000 to eighty nine thousand 15:54.380 --> 15:58.920 will be again 80000. 16:00.050 --> 16:05.870 The nearest 20000 to ninety one thousand will be one leg. 16:06.230 --> 16:07.700 So that is what we are expecting. 16:08.210 --> 16:10.640 So let's put it here first. 16:15.390 --> 16:19.380 It gives eighty thousand when we let's print all of these. 16:52.020 --> 16:59.220 So here you can see it is a rounding to the next or the nearest ten thousand right now. 16:59.520 --> 17:04.860 So for eighty one thousand, it is rounding to eighty thousand for eighty nine thousand nine hundred 17:04.860 --> 17:07.350 resounding to ninety thousand four ninety one thousand. 17:07.650 --> 17:09.120 It is rounding to 90000. 17:09.120 --> 17:11.940 So this is not rounding to the nearest twenty thousand. 17:12.330 --> 17:14.310 Back to the nearest ten thousand. 17:14.310 --> 17:16.770 But we are looking for the nearest twenty thousand. 17:18.240 --> 17:20.670 So let's get for them now. 17:21.390 --> 17:29.160 Let's divide this particular number with twenty thousand. 17:29.170 --> 17:31.020 So let me create another reading. 17:31.030 --> 17:33.870 Everything is equal to twenty thousand. 17:35.640 --> 17:42.480 And look, we divided with all these numbers, so I will simply divide it. 17:47.330 --> 17:47.840 Baby, 17:56.070 --> 17:59.390 and let's get rid of this. 18:04.460 --> 18:05.210 What do we have? 18:05.870 --> 18:07.820 We have four, four, five. 18:08.480 --> 18:11.840 And let's multiply it with the again. 18:20.770 --> 18:23.110 So here you get what we were looking for. 18:23.350 --> 18:31.000 Now, what we have simply done is because we wanted to find out what nearest multiple of 20000 it was. 18:31.240 --> 18:38.920 So we had to divide it by twenty thousand and then round the number and then multiplied with 20000 so 18:38.920 --> 18:41.170 that we could get a multiple of 20000 then. 18:41.680 --> 18:49.420 So this is how you find the multiples or you can see the nearest rounding for our particular numbers 18:49.420 --> 18:49.990 multiply. 18:50.950 --> 18:53.830 Now, let's see. 18:53.830 --> 18:55.330 I want to do this. 18:58.080 --> 19:01.020 With the next one. 19:01.290 --> 19:04.500 So here we are just rounding to the nearest twenty thousand. 19:04.740 --> 19:09.810 But let's say we want to noetic to the next multiple of twenty thousand. 19:09.840 --> 19:16.080 So in this particular case, the next multiple of twenty thousand four, eighty one thousand will be 19:16.290 --> 19:18.590 one like four eighty nine thousand. 19:18.600 --> 19:22.530 It will again be one lap for ninety one thousand and will again be one left. 19:22.560 --> 19:25.140 So these two values are wrong for now. 19:25.470 --> 19:26.640 So let's get this 19:30.210 --> 19:30.630 now. 19:30.900 --> 19:36.750 We want to round these numbers, but we want to round these numbers so that the decimal goes to the 19:37.050 --> 19:38.160 next number. 19:38.280 --> 19:41.790 We want to get the next upward value offered. 19:42.000 --> 19:47.340 So we simply find the stealing of the number instead of rounding up the number. 19:47.640 --> 19:51.240 What the ceiling give ceiling gives the output value. 19:51.250 --> 19:52.930 So we see. 19:54.450 --> 19:55.530 And scroll through down. 20:08.930 --> 20:14.870 Now, again, SEAL is a function of math library, so we will have to see my daughter. 20:21.430 --> 20:22.510 Now, let's get this. 20:22.870 --> 20:24.910 So here you get the results accordingly. 20:26.380 --> 20:34.420 So this was a pretty simple exercise, and it will take you through different mathematical operations, 20:34.420 --> 20:37.480 which you can come across in future. 20:37.720 --> 20:44.560 So it is fine if you faced a problem in solving some of the questions you will learn through the time 20:44.560 --> 20:46.060 once you keep on practicing. 20:46.450 --> 20:48.940 So let's go ahead with the next topic. 20:49.600 --> 20:50.080 Thank you.
