Getting Started with Python: Your First Program in Visual Studio Code

Getting Started with Python: Writing and Running Your First Program

Welcome to the world of coding! In this tutorial, we’ll be harnessing the power of Python and the Visual Studio Code (VS Code) editor. Perfect for beginners, this guide will walk you through everything you need to know to install Python, set up VS Code, and run your first program. This exciting journey begins with the classic Hello, World! program!

Why Python?

Python is renowned for its simplicity and readability, making it an excellent choice for those new to programming. Its wide range of applications—from web development to data science—will allow you to explore various fields as you grow your skills.

Step 1: Installing Python

Let’s start by installing Python. Follow these steps:

1. Download Python: Visit the Python download page. The site will automatically recommend the version based on your operating system.
2. Install Python: Find the downloaded file in your Downloads folder. Double-click it, and during installation, ensure you check "Add Python to PATH" to avoid future path issues.
3. Verify Installation:
• For macOS: Open Terminal, type python3 --version and hit Enter. If successful, you’ll see the installed version.
• For Windows: Open Command Prompt, type python --version and press Enter. A successful installation will show the current version of Python.

Step 2: Setting Up Visual Studio Code (VS Code)

With Python installed, let’s set up your code editor, Visual Studio Code, so you’re ready to write your first script.

1. Download VS Code: Go to the VS Code download page and select the version suitable for your operating system.
2. Install VS Code: After downloading, locate the installation file.
   
   • On Windows, double-click the .exe file and follow the prompts.
   • On Mac, open the .dmg file and drag the application into your Applications folder.
   • On Linux, use the .deb or .rpm file with your package manager.
3. Launch VS Code: Open the application via your start menu or application launcher.

Step 3: Configuring Python in VS Code

Now that VS Code is up and running, let's configure it for Python programming.

1. Install the Python Extension: In VS Code, navigate to the Extensions view by clicking the square icon on the sidebar. Search for Python and install it, preferably the one developed by Microsoft.
2. Select Python Interpreter: Usually, VS Code identifies the appropriate Python interpreter automatically. If not, press Cmd + Shift + P (or Ctrl + Shift + P for Windows/Linux), type Select Interpreter and choose the Python version you installed.

Step 4: Writing and Running Your First Python Program

It’s time for some fun! Let’s write our first Python script:

1. Create a New File: In VS Code, go to File > New File, then select Python as the file type.
2. Save the File: Click File > Save As, and name your file hello_world.py.
3. Write Your Code: In the editor, type the following line of code:
   print("Hello, World!")
4. Run the Program: Ensure your file is saved. Open a new terminal in VS Code by going to Terminal > New Terminal. Click the play icon in the upper right, and select Run Python File.
5. See the Output: Your terminal will display your message: Hello, World!. Congratulations!

Conclusion

Well done! You’ve successfully installed Python, configured Visual Studio Code, and written your very first program.

Each step you've followed is a building block towards your programming skills. Don't hesitate to learn from mistakes and try new things as you continue your journey into coding.
