WEBVTT 00:01.200 --> 00:02.080 Hello, everyone. 00:02.430 --> 00:08.750 In this particular session, we will be discussing about strains we would discuss about various dring 00:08.760 --> 00:16.510 operations like strip split, replace, case change, string formatting and slicing. 00:16.950 --> 00:18.210 So let's begin with it. 00:23.950 --> 00:26.290 Let's start with transcreation post. 00:30.980 --> 00:38.210 A string is a sequence of characters, so a string can have a single character, say, E.. 00:39.860 --> 00:44.870 A string can also have a sequence of characters or just a word. 00:49.540 --> 00:51.100 See what? 00:52.980 --> 00:58.560 A stream can be created by a single code, double or triple code. 00:59.250 --> 01:04.210 So let's see how we can create a string by we have just seen how to create a single code. 01:04.230 --> 01:07.280 So we'll see how to create string using double code. 01:07.560 --> 01:09.780 So I'm creating a sentence. 01:13.730 --> 01:20.810 So this is using double quotes and you can see the string has been created with the same format, but 01:20.810 --> 01:22.280 only the syntax is different. 01:22.310 --> 01:25.000 We have used a similar code here and here. 01:25.040 --> 01:26.160 We have used a double. 01:28.080 --> 01:31.560 Another way of creating a string is using triple quotes. 01:32.550 --> 01:36.720 So here I am using triple code, so I'm saying this is. 01:40.270 --> 01:43.330 Month two lines train. 01:45.360 --> 01:46.110 This. 01:49.340 --> 01:52.160 Go on and. 01:55.710 --> 02:00.000 And let me save this particular string in say that. 02:02.590 --> 02:03.880 So if your friend said. 02:14.910 --> 02:19.360 Now you can see that the multiline string is coming as a multiline comment. 02:19.800 --> 02:24.250 Now, let's say we have a particular word which has gotten it. 02:24.600 --> 02:26.340 So this is a. 02:29.880 --> 02:31.200 Ordinary. 02:34.220 --> 02:36.770 But not so. 02:39.680 --> 02:40.670 Ordinary. 02:42.240 --> 02:50.130 Multiline strength now you can see here I have begun my strength using a triple code, so this understands 02:50.130 --> 02:56.160 that this double code, which has been used inside the same Din's and the single code which has been 02:56.160 --> 03:03.540 used inside the sentence, is a part of the sentence and is not defining on the string inside this. 03:03.900 --> 03:06.810 So it will consider this as a single string. 03:07.560 --> 03:17.010 And this is we get as a response so we can use Dubofsky string, triple string or single code for the 03:17.010 --> 03:22.590 string creation's so that we can distinguish between the codes which are being used in Dohnanyi. 03:22.800 --> 03:29.490 So let's see if I have a single code which is being used inside the string, then I can use either a 03:29.490 --> 03:36.480 multiline string or a double code to start my string so that this particular code would be considered 03:36.480 --> 03:37.800 as a part of the string. 03:38.490 --> 03:40.260 Same applies for double code. 03:40.260 --> 03:47.070 So in case I have a double code in my string, I can use a single code for starting and ending my string 03:47.070 --> 03:49.320 so that the machine would understand. 03:49.540 --> 03:51.630 Then this is a part of a sentence. 03:55.450 --> 04:01.570 The next thing which we can do is we can concatenate multiple strings. 04:03.140 --> 04:08.210 So let's say I create a string named X, which is. 04:10.230 --> 04:10.920 Hello. 04:13.360 --> 04:16.750 My name is Monty. 04:19.070 --> 04:21.680 And why, as. 04:25.610 --> 04:27.850 What is your name? 04:29.330 --> 04:36.410 Now, what I can do is with this particular string, I can combine these strings, so let's run this 04:36.410 --> 04:44.870 particular piece of code and I can concatenate these by using said is equal to X plus Y. 04:45.380 --> 04:48.410 So this would concatenate this and those forms would be. 04:51.070 --> 04:53.090 Hello, my name is Monty, and what is your name? 04:53.110 --> 04:55.000 So these have been concatenated together. 04:56.030 --> 05:02.030 I can also do this in opening statement so I can say something like Brent. 05:05.380 --> 05:07.270 X plus. 05:10.590 --> 05:13.770 Code space, hello. 05:16.060 --> 05:17.580 In brackets, let's say. 05:21.060 --> 05:23.190 And I can also. 05:24.380 --> 05:26.530 Add another string here, say. 05:27.830 --> 05:34.010 So when I do this, it will contain whatever I give in and say this now this is possible because these 05:34.010 --> 05:35.890 are all strings now. 05:35.900 --> 05:37.970 Same thing I can do with numbers. 05:39.300 --> 05:42.510 So let's say I do this with. 05:45.340 --> 05:53.200 Numbers being two plus nine, so this will give me 11 as a result, because now it would understand 05:53.200 --> 05:57.600 that I have given in numbers and I'm using a plus operator. 05:57.760 --> 06:01.160 So this means that I don't want to concatenate these together. 06:01.420 --> 06:03.700 I want to add these numbers. 06:03.850 --> 06:08.500 But in case I want to concatenate these together, what I can do is. 06:09.810 --> 06:16.380 I can simply put these in quotes, and now it would seem that this is a string. 06:17.360 --> 06:19.890 And it would concatenated these together. 06:20.360 --> 06:27.790 But in case you want to try something like let's say you want to try something with a string on a number, 06:28.280 --> 06:31.060 in that case, let's see what would happen. 06:32.090 --> 06:38.240 Now, look, we've got a string to and I'm giving mine as a number, so when I ran this particular piece 06:38.240 --> 06:45.130 of code, I get the error, saying it can only concatenate string, not integer to a string. 06:45.380 --> 06:49.040 So we will not be able to concatenate string with a number. 06:49.260 --> 06:54.570 You can only concatenate string with a string or we can add two numbers here. 06:54.800 --> 06:57.730 So this is what we can do in case of string. 06:57.740 --> 07:03.020 So this is one thing which you need to always remember that in case you want to concatenate two numbers, 07:03.020 --> 07:09.470 you will have to convert them industry and then concatenate in case you want to add two numbers, you 07:09.470 --> 07:15.500 can directly use them and in case you want to concatenate two strings, then that would be possible 07:15.740 --> 07:20.470 by using plus operator, which would act as a concatenated here. 07:23.750 --> 07:43.310 Let's create a string Z, as this is a very I long I string, I like this string now I have created 07:43.310 --> 07:48.730 the string and I want to split the string on I. 07:48.770 --> 07:50.270 So what I can do is. 07:51.350 --> 08:03.320 I can write something like Z dot split, and inside this I can give the character or special character 08:03.320 --> 08:04.580 on which I want to split. 08:04.580 --> 08:05.600 So I'm giving a. 08:06.840 --> 08:14.790 So this gives me the split with I now, in case I don't want to split down, I want to split on the 08:14.790 --> 08:19.550 space, I can give a space here and it would split on space. 08:19.770 --> 08:26.550 If you don't give anything, it will simply don't split because we have not given anything. 08:26.580 --> 08:31.020 So if you just don't give anything, it will split on space by default. 08:32.180 --> 08:34.740 So these are the different combinations we can try. 08:36.080 --> 08:42.560 Now, another thing is using strength, so let's use drip. 08:43.070 --> 08:50.420 So for using strep, what we can do is let's create another string Z and have a lot of spaces in the 08:50.420 --> 08:50.870 beginning. 08:51.800 --> 08:53.910 Now we have a lot of spaces in the beginning. 08:53.930 --> 08:56.180 Let's see something. 08:58.640 --> 08:59.990 Something. 09:02.400 --> 09:11.520 And a lot of spaces, so this is my Z and I want to strip this, so what I can do is I can do something 09:11.520 --> 09:16.800 like Z is equal to Z dot strip. 09:17.700 --> 09:25.770 And when I don't give anything, it will strip off all the white spaces from the right side and the 09:25.770 --> 09:26.970 right left side. 09:27.270 --> 09:30.030 So what I can do is I can simply print. 09:32.520 --> 09:40.020 Zent quickly, so once I do this, it have it has stripped of all the spaces from the beginning and 09:40.020 --> 09:45.900 the end of the thing, what I can do is I can do a strip. 09:47.320 --> 09:51.310 From the left side or the right side, so here I am stripping from the left side. 09:52.220 --> 09:55.750 So it gives me this, but I won't be able to see the spaces here. 09:56.810 --> 10:00.590 Because if you can see, I have highlighted the spaces here. 10:05.930 --> 10:14.000 Another function which we have is replace, so how we can use replaces, we can simply seize it. 10:14.920 --> 10:16.870 Dodd plays. 10:21.290 --> 10:26.220 And in the replace function, we will give the character or the string that we want to replace. 10:26.240 --> 10:28.910 So let's say we want to replace some. 10:30.300 --> 10:30.870 With. 10:32.060 --> 10:33.020 Nothing. 10:39.090 --> 10:39.810 And. 10:42.140 --> 10:48.210 This would give us nothing instead of something, the next thing. 10:48.230 --> 10:52.740 Now, this could be done in a long string, also in a smaller string. 10:52.770 --> 10:55.530 Also, you can replace a larger string. 10:55.560 --> 10:58.350 Also, you can replace just one character also. 10:58.370 --> 10:59.900 So it is completely up to you. 11:00.140 --> 11:06.030 And you can see it has replaced all the occurrences of this particular string in Z. 11:06.590 --> 11:09.530 The next thing which we can do is we can change the keys. 11:10.040 --> 11:14.720 So to change the keys, what we can do is begin. 11:14.960 --> 11:21.500 First of all, I can introduce one more thing to you, which is then function Leane function with just 11:21.500 --> 11:28.520 give the length of said so Lent is 19 characters so you can come visit Zettl. 11:28.520 --> 11:37.100 One, two, three, four, five, six, six devices 12. 11:38.770 --> 11:44.350 So we are discussing mode something something that this will have one, two, three, four, five, 11:44.350 --> 11:49.150 six, seven, eight, nine, and that would be 18 plus one. 11:49.150 --> 11:50.740 Space's 19. 11:52.040 --> 12:00.750 So let's learn about the case, so for keeps changing, what we can do is we can say something like 12:00.780 --> 12:03.470 said Dot Apple. 12:04.560 --> 12:10.090 So it will change the case of Z to Apple, we can see something. 12:10.740 --> 12:15.930 Now, let's assign this to Z also and then protect. 12:19.560 --> 12:22.320 So now the case of Z has been changed to uppercase. 12:22.350 --> 12:30.780 Now, if I want to convert this into a lower case, I can see Z dot lower and it will convert it to 12:30.780 --> 12:31.650 lowercase. 12:32.100 --> 12:35.010 I can also see Z. 12:37.340 --> 12:38.060 Dot. 12:40.590 --> 12:50.730 Capitalize, Z, dot capitalize and Z dot capoulas would capitalize the first character in the string. 12:52.310 --> 12:59.010 Next week, a new string formatting, how do you string formatting is we already have so let's see the 12:59.010 --> 13:02.150 world values of X Y. 13:03.110 --> 13:06.580 So what we can do is let's I want to print. 13:13.050 --> 13:17.690 Hello, my name is Monty, and I can add something more to it. 13:19.090 --> 13:21.310 So what I can do is. 13:22.990 --> 13:31.240 I can either concatenate these and use these as a single string on the thing, what I can do is I can 13:31.240 --> 13:36.030 create placeholders in my strings or that what I will have to do is I will say print. 13:37.000 --> 13:43.450 And inside prison, I can see something like this is. 13:49.160 --> 13:51.230 Oh, sentence. 13:58.460 --> 14:00.200 My name is. 14:02.400 --> 14:03.540 The blank space. 14:06.610 --> 14:07.300 Hello. 14:09.410 --> 14:10.160 Blacks face. 14:11.160 --> 14:13.120 Now, this is the Indicus train. 14:13.590 --> 14:17.010 Apart from that, I can include a dot for MACD. 14:18.190 --> 14:25.860 Which will take off your argument and the argument would be whatever I want to fill in these holy places. 14:26.260 --> 14:30.940 So if I want to fill in, let's say this is this, then I want to add my. 14:32.080 --> 14:34.720 The next thing which I want to add is. 14:36.470 --> 14:41.240 Munsie And the next thing which I want to add is Montay again. 14:43.100 --> 14:49.910 So once I've done this, you see the blanks which I have introduced by these holy places, have been 14:49.910 --> 14:53.910 filled by the values which I have provided in the for Mike. 14:54.170 --> 14:56.090 I can provide numbers also. 14:56.090 --> 14:58.100 I can provide strings also. 14:58.100 --> 14:59.830 I can provide variables also. 14:59.870 --> 15:01.990 That is completely up to my wish. 15:02.450 --> 15:10.190 Another thing, what I can do is instead of using these holy places and of without any police numbers, 15:10.190 --> 15:12.770 what I can do is I can remove this. 15:13.340 --> 15:17.600 So because manses repeating so I don't really want to write it again and again. 15:17.960 --> 15:20.990 So instead of having this, I can say zero. 15:22.980 --> 15:23.520 One. 15:25.140 --> 15:27.780 And one, so this would. 15:29.900 --> 15:36.650 Simply take the values from the indexes, so the zeroth index is mine, so it considers zero here and 15:36.650 --> 15:41.310 the first index is Monte, so it puts Monte in both of these places. 15:41.870 --> 15:48.050 Now, in case I want to switch the places, I can also do something like this. 15:50.310 --> 15:58.780 I will put this here, and instead of zero, I can please one and instead of one, I can play several. 15:59.340 --> 16:03.100 So the index says is what is important to you. 16:03.360 --> 16:07.260 So now, because I have given my team the zero the index, I am putting zero here. 16:07.830 --> 16:09.600 So this is about string formatting. 16:09.910 --> 16:15.300 We will learn about string slicing in the next section.
