Why Check Python Version?

Before we dive into the details of checking the Python version, let’s understand why it’s essential to know the current version. Here are some reasons:

• Ensuring Compatibility: If you’re using a Python script or application, it’s crucial to check the version compatibility with the environment. For instance, a Python 2.7 script might not work on Python 3.8 or later.
• Troubleshooting Issues: When you encounter issues with your Python code, knowing the version can help you identify the problem.
• Update or Upgrade: Knowing the current version is a crucial step in updating or upgrading your Python installation to take advantage of new features and bug fixes.
• Compatibility with dependencies: If your application relies on packages or dependencies, it’s essential to check the compatibility with the current version.
• Identify outdated libraries: If you’re using libraries that are no longer maintained or have been deprecated, it’s crucial to upgrade to the latest version.

Common Python Version Distributions and Compatibility

Python has several versions available, including:

• Python 2: The original version, still widely used but no longer supported for new developments.
• Python 3: The current stable version, recommended for new projects and updates.
• Python 2.7: The last compatible version of Python 2, still maintained for compatibility.
• Python 3.x: Different 3.x versions, with each having its own set of features and improvements.

Checking Python Version using Visual Studio Code (VS Code)
