How to Install and Use Python Environments in Visual Studio Code

When working with Python, it's essential to understand the concept of environments, which play a crucial role in managing dependencies and isolating projects. In this article, we'll explore how to install and use Python environments in Visual Studio Code.

Global Environments vs Virtual Environments

Before diving into Python environments, it's vital to understand the difference between global and virtual environments. A global environment is the default environment where any Python interpreter installed runs. When you run a Python program without specifying an environment, it runs in the global environment by default. This means that any packages you install or uninstall affect all programs running within that environment.

On the other hand, a virtual environment is a folder that contains a copy (or symlink) of a specific interpreter. When you install packages in a virtual environment, they are installed only in that subfolder and do not affect the global environment. Virtual environments are ideal for projects that require specific dependencies to be managed separately.

Installing Python Environments in Visual Studio Code

To install a Python environment in Visual Studio Code, follow these steps:

1. Open the Command Palette by pressing Ctrl + Shift + P (Windows/Linux) or Cmd + Shift + P (macOS).

2. Type 'Python: Select Interpreter' and select an interpreter from the list.

3. If you want to create a new environment, click on the 'Create Environment' button.

Configuring IntelliSense for Cross-Compiling

Once you've installed a Python environment, you can configure IntelliSense for cross-compiling by following these steps:

1. Open the Command Palette and type 'Python: Select Interpreter'.

2. Select an interpreter from the list.

3. Go to the 'Settings' icon in the left sidebar of the VS Code window.

4. Search for 'python.intelliSense.enabled' and toggle it on.

In this article, we've discussed how to install and use Python environments in Visual Studio Code. We've also explored the difference between global and virtual environments and how they can be managed using the Python extension in VS Code. By following these steps, you'll be able to create and manage your own Python environments for your projects.
