WEBVTT 0 00:00.810 --> 00:07.920 Now in the last lesson we looked at how we can use comparatives, such as greater than or is equal to, in 1 00:07.920 --> 00:14.450 order to send a different alert to people who got love scores above 70 and those who got below 70. 2 00:14.500 --> 00:23.310 Now, what if we could find tune that even further? What if we could say, if somebody got above 30 but 3 00:23.580 --> 00:28.610 below 70, then they should get a different alert from the other scores? 4 00:28.680 --> 00:35.820 Well to do this we would have to combine our comparatives. And the three basic comparatives are two ampersands 5 00:35.940 --> 00:36.330 for 6 00:36.390 --> 00:43.760 AND, so whether if condition one is true and condition two is true. You can check to see if either 7 00:43.770 --> 00:47.940 condition one is true or condition two is true 8 00:48.060 --> 00:48.870 by using the 9 00:48.960 --> 00:50.240 OR command, 10 00:50.400 --> 00:56.230 and you can do this using two pipe signs, and that's the straight lines that you see on your keyboard. 11 00:56.250 --> 01:02.820 And finally, as we've seen already, the exclamation mark means NOT, or the opposite of something. 12 01:02.820 --> 01:04.880 So let's take a look at this in practice. 13 01:04.890 --> 01:12.360 So, in between the if and else, let's say we added another if statement and we said, if the love score 14 01:12.450 --> 01:15.410 was greater than 30, 15 01:15.450 --> 01:22.060 so this is condition one, and we combine it using the AND, which are two ampersand symbols on the keyboard, 16 01:22.370 --> 01:28.380 and the second condition is love score is less than or equal to 70. 17 01:28.380 --> 01:34.860 So under this condition we can give people the alert of their love score. If the love score was greater 18 01:34.860 --> 01:35.720 than 70, 19 01:35.730 --> 01:42.090 we tell them that they love each other like Kanye and Kanye, and if they got a really low score, if love 20 01:42.090 --> 01:50.790 score was less than or equal to 30, then we tell them that your love score is this and we give them 21 01:51.030 --> 01:52.360 a different message, 22 01:52.380 --> 02:01.190 for example. So now when we run our code, depending on what we got as a random number, then it will 23 02:01.220 --> 02:04.070 execute different parts of our code. 24 02:04.340 --> 02:09.110 So say if we got above 70 then we get the Kanye loves Kanye. 25 02:09.290 --> 02:16.250 If we got between 30 and 70 then we just get the simple love score, and if we get below 30, then we get 26 02:16.250 --> 02:19.210 told that you go together like oil and water. 27 02:19.430 --> 02:25.100 So this is achieved by using a bunch of if statements that check whether if different conditions are 28 02:25.100 --> 02:32.540 true at the time when we run the code and then we use comparatives to compare the value of a particular 29 02:32.540 --> 02:36.270 variable against another variable or another value. 30 02:36.290 --> 02:42.710 And finally we used combo moves like the AND in order to check whether if two different conditions 31 02:43.010 --> 02:46.880 are both true at the time of checking.
