1 00:00:00,630 --> 00:00:03,920 Hello and welcome to this video. 2 00:00:03,990 --> 00:00:16,980 In this video I'm going to introduce you to what a python statement is what is a python statement a 3 00:00:16,980 --> 00:00:31,580 statement in Python is an instruction to the computer to perform a specified action or task in Python. 4 00:00:31,620 --> 00:00:40,540 A statement can be a single line or it can be multiple line. 5 00:00:40,710 --> 00:00:53,880 Also you need the Python interpreter to translate the statement you write for the computer to understand 6 00:00:55,730 --> 00:01:05,070 the Python interpreter is automatically installed when you install Python. 7 00:01:05,070 --> 00:01:15,660 Let's take a look at how a single line statement can be written before you can write a statement. 8 00:01:15,660 --> 00:01:24,990 You need to invoke or activate the Python interpreter so if you are on a Windows based computer you 9 00:01:24,990 --> 00:01:27,120 can open up your command prompt. 10 00:01:27,300 --> 00:01:32,610 If you are on a Mac you need to open up your terminal. 11 00:01:32,610 --> 00:01:36,810 If you're on a Mac you need to type in Python 3. 12 00:01:36,810 --> 00:01:45,170 Once you have your terminal open if you are on a Windows just type in Python and then just press enter 13 00:01:45,980 --> 00:01:48,830 and that will give you the python shell. 14 00:01:49,460 --> 00:01:58,850 So once a python shell is activated automatically the Python interpreter becomes invoked or active so 15 00:01:58,850 --> 00:02:02,750 to write a simple single line statement. 16 00:02:02,750 --> 00:02:11,350 Basically I can just do a simple metric those seven times seven and press enter. 17 00:02:11,430 --> 00:02:15,930 That is a single line statement because it's on a single line. 18 00:02:15,960 --> 00:02:20,970 If I press enter it gives me the answer. 19 00:02:20,970 --> 00:02:29,760 I can also use a print statement just to print out a single line of text so hard just inside the opening 20 00:02:29,820 --> 00:02:30,820 parentheses. 21 00:02:30,840 --> 00:02:36,820 I will specify the text I want to print on the screen which is hello. 22 00:02:37,950 --> 00:02:46,110 And then I'll close the parenthesis and if I press enter it will just print out the text Hello. 23 00:02:46,110 --> 00:02:53,760 So these are couple of examples of a single line statement because they are statements that are written 24 00:02:54,360 --> 00:02:56,100 on a single line of code. 25 00:02:57,270 --> 00:03:07,530 Let's take a look at how we can write a very basic multi line statement to write a multi line statement 26 00:03:08,010 --> 00:03:10,220 from the Python Shell. 27 00:03:10,290 --> 00:03:18,810 You need two characters so you can use the slash character if you want to write multiple lines or you 28 00:03:18,810 --> 00:03:24,820 can use parentheses to write multiple line statements. 29 00:03:24,840 --> 00:03:33,570 Also if you're using a text editor or an integrated development environment tool that has a text editor 30 00:03:33,660 --> 00:03:40,570 you can write thousands and thousands or even million lines of code inside a text editor. 31 00:03:40,910 --> 00:03:46,520 But the illustration I'm going to show you is just going to be with the python shell. 32 00:03:47,310 --> 00:03:57,600 So in my python shell if I want to write a multiple line statement for example I could say B is a 2 33 00:03:58,440 --> 00:04:05,130 and then you use a slash and you press center and that allows you to add more lines so I can just say 34 00:04:05,580 --> 00:04:17,510 17 and I do a slash again and a press Penta and I can just add one more I just see loss sixteen and 35 00:04:17,510 --> 00:04:18,390 I press center. 36 00:04:18,390 --> 00:04:26,610 Now if I refer to b it will give me the total tool of the addition of all the numbers. 37 00:04:26,610 --> 00:04:30,690 So that's just the simple way you can implement multi line. 38 00:04:30,780 --> 00:04:39,780 He can also use parentheses for example I can say C is equals 2 and I will have the code in parentheses 39 00:04:40,170 --> 00:04:41,760 and I press enter. 40 00:04:41,760 --> 00:04:46,570 This allows me to enter more line of code. 41 00:04:47,460 --> 00:04:59,850 Okay so I just say plus press enter and I can just add another number say 20 press presenter and then 42 00:05:00,120 --> 00:05:04,620 I can just close the parentheses and press enter. 43 00:05:04,650 --> 00:05:12,270 Now if I type in C to give me 30 which is a total so that's one example. 44 00:05:12,300 --> 00:05:18,660 Let's try and do an example that involves a string or a text. 45 00:05:18,660 --> 00:05:22,880 So let me say Greetings. 46 00:05:22,940 --> 00:05:35,190 What I can get this to do is to store some information so C equals to just a hello and they'll do a 47 00:05:35,190 --> 00:05:38,220 slash to give me another line. 48 00:05:38,620 --> 00:05:46,380 And in this line I don't know the text just say hi. 49 00:05:46,740 --> 00:05:48,520 Wish you the best. 50 00:05:48,540 --> 00:05:50,510 There'll be another line. 51 00:05:51,000 --> 00:05:51,820 All right. 52 00:05:51,830 --> 00:05:58,610 And then I can just press enter and that ends that. 53 00:05:58,610 --> 00:06:06,920 Now if I call greetings it will just tell me what I have stored. 54 00:06:06,950 --> 00:06:15,650 These are just some ways that you can implement the multi line and single line statement from the Python 55 00:06:15,650 --> 00:06:16,660 Shell. 56 00:06:16,670 --> 00:06:18,910 Thanks for watching and bye for now.
