Let's cover the awesomeness of primitive data types. What are integers, floats, or strings!? I don't know... Let's find out! In case you missed it, here are the previous parts of the series Python for Beginners, Part 1: How to Download and Install Python Python for Beginners, Part 2: Hello World Exercise Python for Beginners, Part 3: The Turtle Module Python for Beginners, Part 4: Interactive Shell vs. Script Python for Beginners, Part 5: Variables Python for Beginners, Part 6: Strings Python for Beginners, Part 7: Fun Fun Functions Python for Beginners, Part 8: Function Arguments Python for Beginners, Part 9: Loops Transcript 0:00 Hey, guys, what's up? 0:01 So in this video I wanna talk about primitive data types. 0:05 Now we're getting into the adult programming stuff, okay? 0:08 Getting out of the little bit of the baby stuff. 0:10 Even though it's not baby, but, 0:13 you know, let's just submit it. 0:15 So, let's talk about primitive data types. 0:18 What are they? 0:19 (mumbles) 0:22 Let's start out with some basic ones first, okay? 0:25 And I also want to clarify something 0:27 about variables for you guys. 0:29 So, you can't start a variable with a number, okay? 0:33 So if you said 5 is equal to, I don't know, 'hello', right? 0:38 The string 'hello', you're gonna get an error. 0:41 So you gotta start it, 0:42 you gotta start your variable with a letter. 0:45 Now you also can't start it with symbols. 0:47 You can't say something like this 0:49 is equal to 'hello', 'kay? 0:51 You're gonna get an error. 0:54 You can combine underscores with your variables. 0:56 You can say hi_hello 1:00 something like this, okay? 1:01 And that would work for you. 1:04 Okay, primitive data types, what are they? 1:07 So, if I have this thing in the green that you see, 1:11 that is a string, alright? 1:14 So, in this video, 1:17 I think we can just keep it like this. 'Kay. 1:21 So that's a string: 'hello' 1:23 Anything with a quotes around it, 1:25 and you can also put double quotes if you want, 1:27 this is a string data type. 1:30 This terminology is very important to remember. 1:34 Then you have your integers. 1:36 Integers are anything that is like this: 1:40 4.3 (mumbles) 4 1:44 5 , 2 1:45 Those are all your integers, obviously. 1:49 Things that have decimal points, 1:51 in math, they are called decimal numbers. 1:53 In python, we call them floating numbers. 1:56 Okay? So you have floating numbers. 1:58 Like 455.5 ; four hundred and... 2:01 354.90 2:07 Okay? These are your floating numbers. 2:10 So, that's another important thing to remember. 2:14 So, this was just a little primer on primitive data types. 2:19 Just so when I use this terminology, 2:21 you guys don't get confused, 2:22 or like want to throw things at your screen, right? 2:26 Like, "I don't know what he's talking about!" Boom! 2:29 Just, throw your mouse or your socks, don't do that. 2:34 I'm telling you what they are here, 2:37 and feel free to look them up a little bit more 2:39 so you can understand more about them. 2:42 But this is some of the basic ones 2:44 we're going to be dealing with, 2:45 and in the next video I'm gonna talk about things like 2:48 what is a list? What is a dictionary? 2:51 So we're gonna go over those as well, m'kay? 2:54 Just to give you a little foreshadowing into it 2:57 for you advanced people there. 2:59 You wanna learn more, right? 3:01 You want to overachieve. 3:03 A list is basically something 3:05 that holds multiple things at once. 3:08 So, for example, I can say 'banana' and 'apple' 3:13 and 'oranges', like this, right? 3:17 And at the start I can say x is equal to. 3:21 I hate x. I hate one letter variables, 3:23 and most python people do as well 3:26 because it's usually a sign of bad coding. 3:29 Always try to make your names very relevant. 3:31 Get into that habit right now. 3:33 Promise yourself. Cross your heart. 3:36 I don't care what you have to do, 3:38 but work hard on variable naming. 3:41 Even if it slows you down sometimes. 3:43 So no x, no y. Only if you have to. 3:47 It's gonna make your code really hard to read, 3:49 and when you're reasoning through your logic, 3:51 you're gonna not understand what you were doing. 3:52 So, let's say, I don't know, 3:55 fruits is a good variable name. fruits. 3:58 And now, if I call fruits, 4:02 you see a list of that thing. 4:03 Okay, I was talking about primitive data types, 4:06 but I got ahead of myself. 4:07 I started talking about some data structures 4:09 like a list and dictionaries. 4:11 We'll cover all that later. Be patient. 4:14 I'll see you guys in the next video.
