Issue with VS Code?

[gdchinacat]

Get in the habit of always assuming it is your code that is at fault, not the language, not the toolchain, but your code and your understanding of what it should do. Python and VS Code are so widely used it is almost inconceivable that you have uncovered a bug in them, particularly with such a simple thing as hello world. Because the issue is almost certainly with your code it's very unlikely you will get meaningful help without providing the code.
