This snippet goes in your .vscode/tasks.json file. It will run the current python file as the default build task.

• command will invoke the python interpreter that is configured in your workspace settings.
• group will make this task the default build task.
• presentation:focus will focus the terminal window when the task is run.
• presentation:reveal will reveal the terminal window when the task is run.

Change args to any python file if you’d like to run the same file each time.
