// hasInterpreters being false can mean one of 2 things:
// 1. getInterpreters hasn't returned any interpreters;
// 2. getInterpreters hasn't run yet.
// We want to make sure that false comes from 1, so we're adding this fix until we refactor interpreter discovery.

The second part of this operation is short-circuited if await interpreterService.hasInterpreters) returns true, it's not executed all the time, see the MDN documentation on short-circuiting.

(await interpreterService.getInterpreters(resource)).length > 0;

if (!hasInterpreters) {
return [new InvalidPythonInterpreterDiagnostic(DiagnosticCodes.NoPythonInterpretersDiagnostic, resource)];
