Easy to Learn
Python is known for its clear and readable syntax, making it easier for beginners to learn and understand basic programming concepts.
Problem-Solving Skills
Learning Python teaches you essential problem-solving and algorithmic thinking skills that are transferable to other programming languages and domains.
Future-Proofing
As technology advances, Python remains at the forefront of emerging trends due to its adaptability and continuous development.
As you can see, learning Python can equip you with essential skills needed in various industries. It'll also enhance your career prospects, and enable you to contribute to current and future technological advancements.
How to Write Your First Python Code 🙌
When we start learning any programming language, we begin by writing "Hello World" in the terminal.
This is very easy, and it gives us the pleasure of doing something in a programming language, even if we've just started learning that language.
So we're going to do this in Python – but first, I would like to explain some prerequisites that you'll need on your computer.
How to install Python on your machine
There are many ways to code on your computer, or even on your phone – I'm not joking!
Nowadays, it is very easy to code even from your smartphone or a tablet, as there are a ton of websites that help you write, debug, and run your code directly from a browser.
If you think that your computer/device might not be good enough for installing the programming software locally, then you can easily use any cloud-based popular platforms. Among these, GitHub Codespace and Replit are my favorites. You can check them out too:
If you want to set up Python locally on your machine, then you are in luck because there are a ton of resources widely available on the internet to guide you through.
I have also written an depth article to show you the whole process step by step. You can read that article directly from here if you'd like. I also included a video tutorial to help you out.
If you are a Linux user, then Python already comes pre-installed. You can check whether you have Python installed on your system by using the command python3 --version also.
And if you are a Mac user, then you can check out this guide to help you get Python installed and make sure you have the latest version.
There are various ways to write Python code on your local machine. You can use Notepad, Notepad++, Sublime Text, VS Code, or any other text editor. You can also use IDEs like PyCharm.
I will use VS Code for this article. If you're doing the same, you'll want to install the Python extension in VS Code.
We will install more extensions later if we need them.
How to Create a Python File
If we want to create a file for writing Python code, we have to ensure that we add the .py as the extension to the file name.
When you're naming your file, there are a few things to keep in mind. For example, you can add spaces between two words in the file name, but that is not recommended. Instead, you can either use an underscore ( _ ), use camel case ( firstName ), or use the snake case ( first_name ) to better handle spaces.
For now, I am creating a file named Main.py. In that file, I'll write my first Python code:
print("Hello World")
This prints the string in the terminal:
Hello World
We use the print function whenever we want to print something in the terminal. We use single quotes or double quotes in the print function, and we write whatever we want to print in the terminal within the quotes.
This also gives the exact output.
Hello World
Just keep in mind that there are certain scenarios when we should use single quotes and double quotes. But you don't need to worry about that right now – you can learn those later.
Just note that you can't mix the two types of quotes in a single print statement. If you are using single quotes at the start, for example, then make sure you use single quotes for the end. The same thing is applicable in the case of double quotes as well.
Video Walkthrough
I have started a complete Python playlist to teach you Python from basic to advanced. As I am currently a final year computer science student in the Machine Learning major, and I am also researching Machine Learning, Artificial Intelligence, and Neural Networks along with some relevant technologies. This also helps me to keep my knowledge fresh and updated continuously.
The first video from that specific playlist demonstrates everything I have told you up until now. Make sure to watch the video here:
