WEBVTT 00:00.180 --> 00:02.330 OK so you made it to the end hopefully. 00:02.400 --> 00:05.200 I mean I guess you could have skipped forward but you made it to this video. 00:05.220 --> 00:09.390 However you got here at the end of the string function section. 00:09.390 --> 00:15.450 So we have a couple of exercises and they range from pretty straightforward to reasonably complex where 00:15.450 --> 00:18.050 we combine multiple string functions together. 00:18.270 --> 00:20.100 So let's get started. 00:20.100 --> 00:25.340 The first one here is to reverse and uppercase the following sentence. 00:25.380 --> 00:30.000 Why does my cat look at me with such hatred. 00:30.030 --> 00:32.130 I would also appreciate an answer to that. 00:32.310 --> 00:38.130 If anyone can help me but anyway is what we need to do is just take this you can copy it or type it 00:38.130 --> 00:40.730 out and just use my as well. 00:40.770 --> 00:41.670 I should specify. 00:41.700 --> 00:44.120 Don't just manually reverse it and type it. 00:44.130 --> 00:44.700 Uppercase. 00:44.700 --> 00:46.680 I mean using what you just learned. 00:46.740 --> 00:54.090 How can you reverse and uppercase this right then when you're done that the next problem. 00:54.090 --> 00:54.990 This one is a little different. 00:54.990 --> 00:56.790 You don't have to actually do anything. 00:57.000 --> 01:00.220 I want you to figure out what this print out. 01:00.810 --> 01:03.740 So don't just cheat and copy and paste it. 01:03.810 --> 01:08.240 You can do that to check your work of course but try and work through what's actually happening. 01:08.400 --> 01:14.650 We've got a select I've got to replace and it can cat and some word and spaces and symbols and dashes 01:15.250 --> 01:23.190 so give it a shot then move onto the next one here which is to replace all the spaces in book titles 01:23.850 --> 01:25.160 with this little arrow. 01:25.210 --> 01:27.400 It's a dash greater than sign. 01:27.780 --> 01:29.440 So replace every space. 01:29.520 --> 01:32.990 So instead of the space namesake it's the dash. 01:33.100 --> 01:39.870 Or let's just say arrow the arrow namesake and that happens every space and one more thing I'll call 01:39.870 --> 01:41.510 attention to it just appear. 01:41.510 --> 01:43.160 It just says tidal. 01:43.320 --> 01:47.460 So you're going to need to use as to make sure it says title. 01:47.460 --> 01:51.740 So basically your task is to just get this same data printed out. 01:51.780 --> 01:53.810 This exact same format. 01:54.600 --> 01:56.340 Then after that. 01:56.340 --> 01:57.720 Print this out. 01:58.170 --> 02:06.520 So you're going to have the authors the last name printed regularly forwards and then next to it. 02:06.570 --> 02:11.610 You'll have the same author's name printed backwards in reverse. 02:11.610 --> 02:14.820 You might say so if that's what you need to do. 02:14.820 --> 02:17.610 Also pay attention appears as forwards and backwards. 02:17.700 --> 02:20.450 So you need to use as again to do that. 02:20.580 --> 02:29.040 Then once you do that the next one like to print out a full author's name so it's a little more complicated 02:29.580 --> 02:33.030 in caps so we want Jhumpa Lahiri. 02:33.030 --> 02:37.630 So that's author first name and last name combined and uppercase. 02:38.070 --> 02:42.970 And that should happen for every author and then also again the name appears. 02:43.010 --> 02:46.820 The header says full name in caps. 02:46.830 --> 02:48.960 All right then. 02:49.050 --> 02:50.200 Make this happen. 02:50.490 --> 02:59.940 So what this is showing is a title the name sake and then was released in and then the actual date that 02:59.940 --> 03:02.810 we have stored in our database for when it was released. 03:02.910 --> 03:08.530 So you need to combine title was released in and then the year it was released. 03:08.700 --> 03:13.810 And again I called it blurb but just put some label up there. 03:14.760 --> 03:17.350 Then next one here. 03:17.520 --> 03:24.360 Print book titles and the length of each title which is pretty similar to what I had what I did using 03:24.390 --> 03:30.380 author's last names so just print the title and then the number of characters in that title. 03:30.480 --> 03:32.570 As you can see some of them are quite long. 03:33.150 --> 03:35.890 The only other thing I would say is appear. 03:35.990 --> 03:36.620 Pay attention. 03:36.620 --> 03:41.420 We have character count so use as you get it right now. 03:42.180 --> 03:46.960 Then finally this one combines three different pieces of data. 03:47.170 --> 03:54.370 We'd like to have a shortened title so I believe this is 10 characters one two three four five six seven 03:54.400 --> 03:54.890 eight nine. 03:54.900 --> 03:55.290 Yes. 03:55.290 --> 04:04.650 So the first ten characters and then a dot dot dot afterwards and call that short title then we'll have 04:04.650 --> 04:05.790 the author printed out. 04:05.790 --> 04:14.060 But the way it should be printed is a last name followed by a comma followed by first name and then 04:14.330 --> 04:15.360 quantity. 04:15.560 --> 04:22.250 So quantity should not just be the number we have in stock but it should be the sentence 12 in stock 04:22.250 --> 04:24.010 or 104 in-stock. 04:24.110 --> 04:30.560 So there's a lot of pieces here and each one of these three is going to require multiple string functions 04:30.650 --> 04:31.820 to make it work. 04:32.360 --> 04:34.190 So give it a shot. 04:34.190 --> 04:35.900 This one is a little more challenging. 04:35.900 --> 04:36.910 So don't panic again. 04:37.010 --> 04:39.670 If you don't get it but try. 04:39.920 --> 04:42.050 And then in the next video solutions.
