Python Basics for Kids | What is Python Coding Language? | Why Python is So Popular? | Use of Python

Key Takeaways

Hello everyone, welcome back to our channel code for kids. How are you all? How was your day? I hope you're enjoying your day. My name is Shreddha Singh and uh today we will start one new module we can say new series which is Python programming. So who can who can watch this video? Suppose if you are in grade 2 or three till grade 10 you can uh watch this video okay because here we are going to be take all the things like what is Python why we are using the Python everything we are going to be learn okay the very first thing if you want the basic thing about coding already I have lots videos you can watch my playlist you will get it. Okay. So what is Python programming language? It's very common thing every child wants to know what is Python. Okay. So we can say Python is one programming language. As a human being we know several languages like for example English, Spanish, German, any language we can say okay in the same way for computer also we have a different languages okay Python is one of them if you will see we have a C, C++, Java, JavaScript, Ruby, Scala there are lots of programming language okay but we why We are learning the Python. It's most important question. So we can say Python is very easy programming language. It's very easy to understand. The code is very simple. Okay. If you will learn the Python. So you can use this knowledge in data visualization. You can use this knowledge in the machine learning in robotics in Raspberry Pi. So there are lots of field where you can use the Python. Okay. So we can say Python is our uh interpreted interactive object oriented and highlevel programming language who created the Python. So he's the person who created the Python during 1985 to 1990. Okay. So we have a lots of source code that is available in the internet also you will get it. Okay. So we can say Python is object-oriented scripting language. It is readable like anyone can read the code. It's a simple English language. There are English keywords that uh we are using in the Python. Okay. Okay, the next part, let me open the next slide. What are the features of Python? Like if you are learning the Python, so what are a different benefits that you will get if you will learn the Python. So we can say it's very easy to learn. Okay, there has a few keyword. The simple structure, we have a very simple structure here. the syntax is very clear. Okay. So that's why this allows the student to pick up the language quickly. Okay. Like it's very easy language. Anyone can learn the Python. If you know the English language, you know the keywords. Okay. If you have a little bit idea in the coding, if you are interested in coding, you can learn the Python. Okay. The next feature is easy to read. The Python code is more clearly defined and visible to the eyes. Okay, you can read it, easy to maintain. So, Python source code is very easy to maintain. There are broad standard of library that we have. Okay. The mode is very interactive like you can run your program very easily. You can debug it. So everything is very user friendly. Here we have the next features which is portable. Portable means you can run your Python in variety of hardware like you can run in the laptop or if you have a iPad or if you have a MacBook or if you have a tablet. So you can run your Python program anywhere. Okay. So the next is extensible. We have a lots of models also in the Python. So we can use that. Okay. Then we have a databases that also we can use here. The databases like how to store the data. So each and everything we are going to be see one by one. Okay. The next thing is if you already know some programming languages like C, Java, C++ then also you are able to understand it very easily. Okay. So we are going to be execute a Python code. Now let me show you what is the first line of code. How you can print anything in the Python that we will uh use. Now, so it's very simple in a Google. There are lots of platform that we can use for the Python. Uh one very favorite platform for the student is Google Collab Notebook. Like we need to just search for Google Collab Notebook. I'm going to provide you this link as well in the description box. So directly you can click here. This is the official link. The symbol is infinity in the maths. So this is the official website Google collab. You need to just click on new notebook. So what will happen in your Google drive whatever account you signed in here. So by default in your Google drive it will create your projects. Okay. So, it's loading. I want a new notebook. Oh, okay. My Google Drive the storage problem. Okay. Let me let me connect with a different one. Okay, it's the Google collab notebook. So if your drive is full, it will not allow you to create a project because by default it is saving the project in your drive only. Okay. So once you will click on new notebook you will get these kind of thing. It is loading. See, perfect. So, it's working fine. Here, this is our Google collab notebook. Over here, uh we are going to be just write the code and with the help of this run button, you can run it and in one notebook you can create multiple programs. So, that's why uh no need to create a new project again and again. In a single notebook you can execute multiple programs. Okay. Suppose this is my first program. I wanted to just write print. I have to just print something like print. I will uh write our channel name which is code for kids. If you will click on this run button, so it will print something here which is code for kids because over here we added. So as you can see this is the result. So in order to print anything we need to follow this pattern. Suppose the very first thing we have to write this keyword. Print is a keyword. Okay. You cannot write P in upper case. Why? Because it will give you the error. This is case sensitive. If we have a P in lower case, so you need to write P in lower case only. See, we are getting this error. If you will get the red red line, it means you have a error. If you will take your cursor here even it will uh give you your error name as well. So we have to take a print after writing the print we need to open and close the round bracket. This is the syntax to print anything you have to write a word print you need to take opening and closing round bracket. Then either we can use the single apostrophe opening and closing or we can use the double apostrophe the double quotes. Okay. Suppose now I wanted to print my name is Shredda Singh. Okay. Now see uh what we will get the result. First we will get code for kids. Then we have my name is Shreddha Singh. Okay. Suppose I wanted to print one more statement which is again print uh today we we are learning Python. Okay. Today we are learning the Python. So now if you will run so you will get three statements. One is code for kids which is the first line. Then my name is Shreddha Singh. Today we are learning Python. Okay. So in this way you can print something. You can print something. Okay. So that we have here which is our second slide. So if you want I'm going to provide you this slide as well. I will uh keep this slide in my Google drive. I'm going to give you the link so directly you can access it. Okay. See how to print anything. It's very simple. You have to use print and then just try to use hello world or anything you can print. Okay. So this is the first concept which is how to print something. The second concept that we are going to be learn today is Python identation. Now what is this identation? Okay, in other programming languages if you know there is a brackets we are using but in Python we are not using any bracket. We are using the space. Okay. So if you have any error which is related to space so in your result you will get this is the identation error. So you have to find where you have a mistake of space. Okay let me show you let me show you what is the meaning of that. Let suppose this is our one program. We wanted to add one more program. So you need to click on this plus code section. you will get one more space. Suppose I wanted to write one condition. If five is greater than two, we need to print. We need to print five is greater. Now if I'm going to write run it you will get five is greater but if you will see we added one condition if five is greater than two I have to print something but what is my second line after if it is it automatically added the spaces. If you will remove the space and then if you will run see this is called as a dentation error. We need to expect some space before your print. Okay. So it means this print belongs to this if condition only. If you have any thing which is belongs to inside if condition you have to give the space that is called as identation error. If you have a notebook you need to make it you need to make a notes. Okay like what is identation error. So if you have a any mistake which is related to space that is addentation error and where we have to add the space if you have any condition inside that condition you need to print something at that time you need to add the space. Okay. So this is the next part which is ident. Okay. Next thing what is variables? If you know the scratch, if you know any other languages, always we are using the variable. Okay. So variable is something like we need to store something like if I will ask you what's your name? You will tell me your name. So now next time I'm not going to ask you what's your name because now I will remember your name. Right? It means I stored your name in my memory. In a same way for computer also if you want to store something we will require some variables. Okay. So we can see variable act as a container where we have to store something. Suppose you want to eat the ice cream. You will take one vessel where you can take the ice cream. Right. Okay. So in a same way variable act as a container. If we want to store something for that we are using the variables. Okay. Got it? So how to print that? Let me show you. Suppose I have one more code section. In a variable I'm just writing hello world. Now I want to just print a. We are not printing the hello world. Now we are just printing the a. So the result is same. What we did here inside a first we stored it. Now this a contains hello world. Okay. And that we are printing here. Got it? So if you will print a, it will print hello world. Why? Because in this a we have hello world. So that is called as variables. Okay. The next thing we have a comments. Now what is the comments? It's very simple. Suppose while creating a program uh every people they are not a technical person we have to write some extra information about any line. Okay. So that we can write in the comment. So what will happen your compiler will not execute that particular line. Suppose I have to just write uh hash this is variable. This is variable. Now if I will write you will get hello world. We are not getting this. But if someone will open your program if they will get this is variable with uh the hash symbol is the comments. Okay. So they are able to identify what is this. Okay. So that's why we are writing the comments with the help of hash. If I will remove it, you will get the error. The error is something like what is this? Okay, but if you will put the hash symbol, it means or compiler will treat this as a uh comments. Okay. So in order to use the extra information in your project always you have to go with comments. Okay. So why we are using the comments? it uh we can say comment can be used to explain the Python code. Comments can be used to make the code more readable. Then comments can be used to prevent execution when testing the code. Okay, you will not get the error if you will write anything in the comments. Okay, I already explained you what is variable. So variable is something like if we want to store something that we can store in the variable. Okay. Then this is most important thing case sensitive. Python is case sensitive programming language. It means if we use lower case a here while calling uh we are not able to call the upper case it will give you the error. A is not defined because in computer the meaning of the binary code of this A lower case A and upper case A is different. So if you will define anything in the lower case while calling also you need to use the lower case. If you will define anything as a upper case, so while calling you have to use the upper case always you need to write the same name otherwise you will get the error. Okay. So this is called as case sensitive. Python is case sensitive programming language. Okay. So in this video as you can see we learned about some concept which is the very first thing what is Python. Okay the second thing features of Python why we are using the Python how to print some statement that also we did then what is identation error what is comments what is variables what is case sensitive. So this the this video is about the basics things of the Python. Okay. In the next video we are going to be learn about all these concepts one by one. Okay.
