WEBVTT 00:00.670 --> 00:05.020 In some situations you will want to use a variable's value inside a string. 00:05.050 --> 00:11.260 For example, you might want to use two variables to represent the first name and the last name respectively, 00:11.260 --> 00:16.870 and then combine those values to display someone's well, full name. 00:16.870 --> 00:20.830 So here we will write first name. 00:21.130 --> 00:22.990 Or actually, let's instead of Y. 00:23.020 --> 00:26.320 Let's make manipulations on Oxford Academy's string. 00:26.320 --> 00:27.190 So. 00:29.300 --> 00:30.530 Let's make the. 00:32.150 --> 00:33.140 First name. 00:33.590 --> 00:34.580 First name. 00:35.720 --> 00:38.360 First name here, it's Oxley. 00:38.360 --> 00:42.980 And here last name is Academy. 00:43.100 --> 00:47.480 So now we will we will write full name. 00:48.170 --> 00:49.310 It's going to be. 00:50.430 --> 00:51.090 Here. 00:51.210 --> 00:53.400 F here. 00:53.460 --> 00:54.480 First name. 00:55.650 --> 00:57.780 And last name. 00:59.120 --> 01:02.060 And after that we will print the full name. 01:04.530 --> 01:08.040 Let's increase the text size a little bit so you can see it better. 01:10.540 --> 01:11.620 A thanks. 01:12.100 --> 01:14.380 Let's make the text size 33. 01:16.100 --> 01:17.150 That's perfect. 01:19.240 --> 01:25.660 So here to insert a variable's value into a string. 01:25.690 --> 01:26.000 Oops. 01:26.800 --> 01:32.260 Insert variable's value into a string place the letter F. 01:32.500 --> 01:33.130 Sorry. 01:33.280 --> 01:36.460 Here, place the letter F. 01:37.230 --> 01:42.540 Immediately before opening a quotation mark here. 01:44.260 --> 01:44.590 What?

04:57.400 --> 05:04.780 So let's instead of this, let's delete this braces, delete this print function. 05:04.780 --> 05:08.380 And now we will write message here. 05:08.770 --> 05:12.970 So we got the first name, last name, full name and message. 05:13.300 --> 05:13.840 All right. 05:14.700 --> 05:22.350 So now we will just print the message and we will get the same output again.
