Click the Run Python File play button in the top-right side of the editor. The button opens a terminal panel in which your Python interpreter is automatically activated, then runs python3 hello.py (macOS/Linux) or python hello.py (Windows): There are three other ways you can run Python code within VS Code:

By using the .py file extension, you tell VS Code to interpret this file as a Python program, so that it evaluates the contents with the Python extension and the selected interpreter. Note: The File Explorer toolbar also allows you to create folders within your workspace to better organize your code.

The Python extension offers various ways to run Python code without extra configuration. Select the Run Python File in Terminal play button in the top-right of the editor. Select one or more lines, then press Shift+Enter, or right-click and select Run Selection/Line in Python Terminal. This option is convenient for testing just a part of a file.

There are two additional ways you can interact with a Python REPL in VS Code. The VS Code Native REPL for Python builds upon the classic Python REPL and provides additional features, such as Intellisense and syntax highlighting to make your Python development experience more efficient.
