Installing Python extensions in Visual Studio Code for beginners

Understanding the Basics of Visual Studio Code

Visual Studio Code (VS Code) is a powerful and popular source code editor developed by Microsoft, favored by developers for its robust features and flexibility. It offers extensive support for various programming languages, including Python, making it a preferred choice among Python developers. Before diving into installation of Python extensions, it’s essential to familiarize yourself with the basic functionalities of VS Code.

Why Use Python Extensions in VS Code?

Python extensions enhance your coding experience by adding several valuable features like IntelliSense code completion, code linting, debugging capabilities, and integration with version control systems. By using Python extensions, you’ll improve your productivity and streamline your coding workflow, making it easier to write, debug, and maintain your Python applications.

Step 1: Install Visual Studio Code

If you haven’t installed VS Code already, start by downloading it from the official website. The installation process is straightforward; just follow the prompts as you would with most software installations.

For Windows:

1. Download the installer.
2. Run the downloaded .exe file.
3. Follow the on-screen instructions to complete the installation.

For macOS:

1. Download the .dmg file.
2. Open the file and drag the Visual Studio Code icon to your Applications folder.

For Linux:

VS Code can be installed via various methods depending on your distribution. For Debian-based systems, use:

sudo apt update
sudo apt install code

For RPM-based systems, you can utilize the following command:

sudo rpm --install code.rpm

Step 2: Setting Up Python

Before you can start using Python extensions, ensure Python is installed on your system. Download the latest version of Python from the official Python website, and follow the installation instructions for your OS.

For Windows:

1. Download the installer.
2. During installation, check “Add Python X.X to PATH”.
3. Complete the installation as prompted.

For macOS:

Python 2.x comes pre-installed with macOS, but you should install Python 3.x. Use Homebrew:

brew install python

For Linux:

You can install Python using the terminal:

sudo apt install python3

Step 3: Launch Visual Studio Code

Once you have installed VS Code and Python, launch Visual Studio Code by clicking on its icon in your applications or typing code in your terminal (if you added it to your PATH).

Step 4: Open the Extensions Panel

To enhance your Python development experience, you’ll need to install relevant extensions:

1. Click on the Extensions icon on the Activity Bar on the side (or use the shortcut Ctrl+Shift+X).
2. This will open the Extensions view.

Step 5: Install the Python Extension

Search for the “Python” extension developed by Microsoft:

1. In the Extensions view search bar, type “Python”.
2. Look for the extension that shows “Python” with a publisher name of Microsoft.
3. Click on the green “Install” button.
4. After installation, the button will change to “Uninstall,” indicating that it’s been successfully added.

Step 6: Configure the Python Interpreter

After installing the Python extension, you need to set up the Python interpreter:

1. Open the Command Palette by pressing Ctrl+Shift+P.
2. Type and select “Python: Select Interpreter.”
3. Choose the correct Python interpreter installed on your system (typically named like Python 3.x).

Step 7: Install Additional Useful Python Extensions

While the main Python extension is essential, other extensions can further improve your coding experience. Consider installing the following:

1. Pylint

Pylint is a static code analysis tool that looks for programming errors, helps enforce a coding standard, and can automatically format your code:

• Search for “Pylint” in the Extensions view.
• Install it by clicking on “Install.”

2. Jupyter

If you work with Jupyter Notebooks, install the Jupyter extension:

• In the Extensions view, search for “Jupyter.”
• Click “Install.”

3. Python Docstring Generator

This helps create docstrings efficiently:

• Search for “Python Docstring Generator.”
• Install it by pressing the “Install” button.

4. Visual Studio IntelliCode

This extension enhances IntelliSense by providing AI-assisted recommendations:

• Look for “Visual Studio IntelliCode” in the Extensions view.
• Install to enrich your coding experience.

Step 8: Create Your First Python File

To start coding, create a new Python file:

1. Click on your workspace or folder where you want to save your project.
2. Right-click and select “New File.” Name it hello.py.
3. Type the following code:

print("Hello, World!")

4. Save the file using Ctrl+S.

Step 9: Run Your Python Code

To execute your Python code in VS Code, you have a couple of options:

Option 1: Running in the Terminal

1. Open the integrated terminal (`Ctrl+“).
2. Type python hello.py and hit Enter.

Option 2: Using the Run Button

1. Click the green triangle play button located at the top right of the editor.
2. This option also allows you to run your code easily without leaving the editor interface.

Step 10: Debugging Your Code

VS Code comes with a robust debugging tool:

1. Set breakpoints by clicking in the gutter next to the line numbers in your code editor.
2. Open the Debug view by clicking the Debug icon on the Activity Bar.
3. Click on the green play button to start debugging.
4. Use the Debug Console for variable inspection and command execution.

Step 11: Version Control Integration

To effectively manage your code changes, integrate Git into VS Code:

1. Initialize a new Git repository or open an existing one.
2. Use the Source Control icon to stage and commit changes.
3. Push your changes to a remote repository like GitHub, allowing for collaboration and version history.

Step 12: Learn and Explore More

Once you’re comfortable with the basics, explore the vast ecosystem of extensions in the Visual Studio Code marketplace. Join online communities, visit forums, or check out documentation related to Python development in VS Code for more tips and techniques.

By following these steps, you’ll set up a potent Python development environment in Visual Studio Code that will enhance your coding skills, facilitate easier debugging, and streamline your workflow. Dive into project work and enjoy the journey of coding in Python with this amazing editor!
