Downloading the Python Extension VSIX File

To install the Python extension in Visual Studio Code (VS Code) offline, you first need to obtain the extension package in VSIX format. The VSIX file is a compressed archive containing all necessary files for the extension to operate without requiring an internet connection during installation.

The official Microsoft Python extension can be downloaded from the Visual Studio Marketplace. Since the marketplace does not provide a direct download link on the website, you must use a third-party service or a direct URL to fetch the VSIX file. Here are common methods to obtain the Python extension VSIX file:

Use a trusted third-party site such as [Open VSX Registry](https://open-vsx.org/) which often hosts extension VSIX files.
Utilize a browser extension or online tool designed to download VS Code extensions as VSIX packages.
Use the command-line tool `vsce` or `azure-devops` CLI if you have access to the extension source repository.

Ensure that the downloaded VSIX file version matches the VS Code version installed on your machine to avoid compatibility issues.

Installing the Python Extension Offline in Visual Studio Code

Once you have the Python extension VSIX file, installing it offline in VS Code is straightforward. Follow these steps:

Open Visual Studio Code.
Navigate to the Extensions view by clicking on the Extensions icon in the Activity Bar or pressing `Ctrl+Shift+X`.
Click on the ellipsis menu (three dots) in the top-right corner of the Extensions pane.
Select the option “Install from VSIX…” from the dropdown.
Browse to the location of the downloaded Python extension VSIX file and select it.
The installation process will begin immediately, and once completed, VS Code will prompt you to reload or restart to activate the extension.

After installation, the Python extension will be fully functional without requiring internet access, allowing you to leverage features such as IntelliSense, debugging, and linting offline.

Configuring Python Interpreter Offline

With the Python extension installed offline, it is essential to configure the Python interpreter that VS Code will use for running and debugging Python code. Since VS Code cannot download interpreters automatically without internet access, you must have a local Python installation ready.

To configure the Python interpreter:

Ensure Python is installed on your system, and note its installation path.
Open VS Code and open the Command Palette using `Ctrl+Shift+P`.
Type “Python: Select Interpreter” and select the command.
Browse through the list of detected Python installations or manually enter the path to the Python executable.
Select the desired interpreter.

This configuration enables the Python extension to use the specified interpreter for code execution, linting, and IntelliSense features offline.

Managing Dependencies and Libraries Offline

When working offline, managing Python packages and dependencies requires pre-planning since you cannot use `pip` to download packages from the internet directly.

To handle dependencies offline, consider these approaches:

Pre-download packages: Use a machine with internet access to download the required packages as wheel (`.whl`) files using the command:

“`
pip download -d
“`

Transfer packages: Move the downloaded `.whl` files to the offline machine via USB or other means.
Install packages locally: On the offline machine, install packages using:

“`
pip install –no-index –find-links= “`

Use a local package repository: Set up a local PyPI mirror or repository to serve packages internally.

By preparing dependencies in advance, you ensure a smooth development experience in VS Code’s offline environment.
