Monaco Editor Playground Code

const value = /* set from `myEditor.getModel()`: */ `# '100_000' should be formatted as a single value per https://peps.python.org/pep-0515/
numeric_literal_example = 100_000`;

// Hover on each property to see its docs!
const myEditor = monaco.editor.create(document.getElementById("container"), {
	value,
	language: "python",
	automaticLayout: true,
});

Reproduction Steps

Open the playground link. Verify that 100_000 is formatted inconsistently.

Actual (Problematic) Behavior

Numeric literals with underscores are not highlighted as a single value by the syntax highlighter.

Expected Behavior

Numeric literals with underscores should be highlighted as a single value, as is done in VS Code.

Additional Context

Numeric literals with underscores were proposed in https://peps.python.org/pep-0515/ and have been supported since Python 3.6.
