Python Installation
Before you write your first line of Python code, you need to set up the Python environment on your computer. Thankfully, it’s a simple process.
Installing Python
To get started with Python, here’s what you need to do:
Visit the official Python website:
Head over to python.org.Download the installer:
Choose the correct version for your operating system (Windows, macOS, or Linux). If you’re on Windows, make sure to select the 64-bit version unless you know otherwise.Run the installer:
Double-click the downloaded file and follow the setup instructions. Be sure to check the box that says “Add Python to PATH”—this makes using Python from the terminal much easier.
Once installed, you can confirm everything worked by opening your terminal or command prompt and typing:
python --version
You should see the version number of Python you just installed.
Writing Your First Python Program
You can now write Python code in any environment of your choice. Beginners often start with:
The built-in Python IDLE
A lightweight code editor like VS Code
Or even an online compiler like Replit or Google Colab
Let’s try the classic “Hello World” example:
print("Hello World !!!")
Save the file as hello.py, and run it in your terminal like this:
python hello.py
You should see the output:
Hello World !!!
Just like that, you’ve run your first Python program!
Installing Packages with pip
Python becomes even more powerful when you add external libraries. To do this, we use a package manager called pip. It usually comes bundled with Python, so there’s no need for a separate installation.
To install a library, use the following command:
pip install package_name
Summary
You’ve now set up Python, written your first script, and learned how to install external packages. With these basics covered, you’re ready to explore Python’s core features.
