WEBVTT 00:00.110 --> 00:02.180 This is the first activity of this course. 00:02.180 --> 00:06.380 And let me just start by explaining what we're going to do in those activities. 00:06.380 --> 00:12.230 So I will always start first with an introduction video like this one here to give you a challenge. 00:12.230 --> 00:14.540 So I explain to you what challenge we're going to do. 00:14.570 --> 00:18.410 And this challenge is going to make you practice what you have just learned before. 00:18.410 --> 00:19.880 So practice what you learned before. 00:19.880 --> 00:25.460 And as we go further in the course also it will help you to combine different concepts. 00:25.490 --> 00:25.700 Okay. 00:25.730 --> 00:31.130 Then after I give you the challenge, it's your turn to work on the challenge and try to solve it on 00:31.130 --> 00:31.700 your own. 00:31.700 --> 00:35.720 And you can also watch the previous videos if you need to, so you can better understand the concepts 00:35.720 --> 00:36.800 and how to apply them. 00:36.800 --> 00:43.580 And after you have worked on the activity well, the next video is the complete, detailed step by step 00:43.580 --> 00:45.830 solution for that challenge. 00:45.860 --> 00:49.250 All right, so what do we want to do for this first activity. 00:49.250 --> 00:56.270 Well the goal is to create a function that will concatenate two strings and put them uppercase okay. 00:56.300 --> 01:01.700 So for example first string I will say let's say you have a hello. 01:01.700 --> 01:05.630 And the second string is going to be world okay. 01:05.660 --> 01:08.930 So you will put those two strings inside variables of course. 01:08.930 --> 01:14.630 And then the result is going to be hello world like that. 01:14.660 --> 01:15.020 All right. 01:15.020 --> 01:17.280 So you will concatenate the two strings. 01:17.310 --> 01:21.600 Note here you also have to add a space and everything will be uppercase. 01:21.630 --> 01:27.000 Now there is one thing missing is how to actually put a string uppercase. 01:27.030 --> 01:30.000 Well let's say you have the string here. 01:30.030 --> 01:33.000 You just do dot upper. 01:33.030 --> 01:35.310 You have the upper function here. 01:35.340 --> 01:35.520 Okay. 01:35.550 --> 01:36.540 So you can use that. 01:36.540 --> 01:42.210 And the result of that this is going to give actually that in uppercase. 01:42.240 --> 01:42.570 Okay. 01:42.600 --> 01:44.490 And how to concatenate strings. 01:44.490 --> 01:48.570 We've actually seen that with data types I think you just. 01:48.660 --> 01:55.530 So let's say you have a string a you just do plus a string B okay. 01:55.560 --> 01:59.220 And the result is going to be AB okay. 01:59.250 --> 02:02.850 So you can use the plus symbol just to concatenate two strings. 02:02.850 --> 02:04.920 And so with this you have enough information. 02:04.920 --> 02:11.040 You can create now a function with two parameters that will take two strings and then return the result 02:11.040 --> 02:14.820 which is the concatenation of those two strings uppercase. 02:14.820 --> 02:18.720 And then you can print the result so you can see if it's correctly working. 02:18.720 --> 02:19.020 Great. 02:19.020 --> 02:20.820 So now it's your time to work on this. 02:21.030 --> 02:25.620 I will recommend you to take enough time to do it even if it seems hard. 02:25.650 --> 02:29.430 Okay, you can go back to previous videos, experiment a few different things. 02:29.460 --> 02:29.760 Okay. 02:29.790 --> 02:33.060 And then I have the solution in the next video.
