Question 7

Suppose class `child` inherits from class `parent`, and `item` is a `child` instance. What does `isinstance(item, parent)` return?

  1. It raises TypeError because the classes differ.
  2. It returns false because only exact instances match.
  3. It returns true because subclasses are included.Correct answer
  4. It compares the textual class names and returns false.

Explanation

The check accepts instances of the named class and of its subclasses, so a `child` instance satisfies a test against `parent`. Requiring an exact class match would describe a direct `type` comparison, not `isinstance`.
