Python tutorial 3: How to create Python Script using IDLE by Manish Sharma

Key Takeaways

so in the previous tutorial we used command prompt to write our very first Python program the only problem with that approach was that we could not save the code we wrote for later use the solution to this problem is to write the code on to a file and save that into our operating system that's exactly what we will be learning today Musab internet i am manish from rebellionrider.com and welcome to another tutorial of an awesome series of Python programming in today's tutorial we will learn how to create scripts in Python programming version 3 to do that we will be using IDL e editor of Python language so without wasting time let's get started but before that please consider giving this video a thumbs up and subscribe to the channel if you haven't already now let's start in order to create a Python script we have to create a file with a compatible file extension most widely used file extensions for Python scripts is dot py and some less used ones are dot p YW and dot py 3 dot py 3 is a new extension introduced with the version 3 of Python programming language famously known as Python 3 it is rarely used to file extension in Python programming dot pyw is the Python file extension for Windows and the scripts with this extension are executed with Python w dot exe whereas all other python scripts will be executed with python dot exe another Python supported file extension is dot py c as we learned that python is an interpreted programming language therefore whenever we interpret python scripts using python interpreter it automatically generates a file with dot py c extension corresponding to the scripts you must be wondering what does it dot py c file consists similar to programming language like Java Python interpreter compiles the source code of your scripts into a special machine code called bytecode bytecode is then executed by pythons virtual machine I suppose there are in total 19 or maybe more Python supported file extensions in order to save your time I will do a pre Facebook note explaining all those extensions on my Facebook page you can find the link in the description that being said let's move ahead in order to keep everything organized let's first create a directory where we will save all our Python scripts I'm going to create this directory in my document folder which is pretty much empty as you can see here you can create a folder anywhere you want in your operating system and name it whatever you want I will name this folder python tutorials great next we have to create a Python script physically a script is a file which contains a set of instructions and has a unique name as well as a dedicated file extension which is accepted by the language in python programming language that dedicated extension is dot B Y so let's start with creating a text file and then we will change its name and extension now go to the new items and choose text to document this will create a new text file now we have to rename it you can name your Python script of whatever you want but make sure it's extension must always be dot py I will need my script as T ut3 dot B Y you might get this warning simply hit yes and move ahead now you will see that the icon of your file has been changed that indicates that you have successfully created an empty Python script now we will learn how to edit a Python script using IDL egy in order to write some code onto this script we need to open it with some sort of IDE or editor luckily Python installation comes with a free IDE known as IDL e IDL e stands for integrated development and learning environment it is a graphic user interface which lets you write edit and execute a Python program can launch it either directly from your Start menu or from the right-click menu of the script file let me demonstrate right-click on the script which we just created and choose edit with ideally you must have this option in your right-click menu if you don't then please check the installation video of Python 3 anyways here we have an ideally editor open for us now let's write a very simple code onto our script let's do one thing let's write a code that will show you the latest version of Python installed on your system how about that I think it's a great idea let's do it wait I think this default phone is pretty small and almost unreadable let's fix it and then we will write the rest of our code go to options choose configure ideally font phase is set to courier new I'm good with this font but I am NOT happy with the font size so by default it is set on 10 let's increase it to say 18 good also let's make it bold too now let's also change the theme go to highlight tab and change the theme from ideally classic to ideally dark create now hit apply and ok now I guess this will be comfortable for our eyes now let's write the remaining code in order to print the latest version of Python we need to use the version method from sis module and to do that we first need to import the said module into our program that is what we did in the first line in the second line we just printed a formatted character string in the third line we call the version method of says module that completes our code now we have a complete Python script in our hands next we have to learn how to execute this script let's do that executing the code using ideally is as simple as slicing butter to execute the code in really first you need to save the changes you have made in the script simply press ctrl + S and you are done next go to run choose run module or you can simply press f5 function key this will launch your Python shell where you can see the output of your program as you can see here the latest version of Python installed is three point seven point one ideally is a very minimalistic IDE with very basic features for example it doesn't come with a debugging tool it justifies its name integrated development learning environment and as it's good for learning purposes but not suitable for intense coding anyways in the next video we will be learning how to execute Python script using command prompt so stay tuned meanwhile I want you to comment and let me know if you have ever used to debug feature of an IDE for your code remember I'm waiting for your comments and very eager to read them moreover do make sure to give this video a thumbs up and share it with your friends on your social media most importantly subscribe to the YouTube channel if you haven't already thanks for watching this is manish from rebellionrider.com
