Solution 1: Basic Dashboard Prototype

Completed idea

A Dashboard can clone itself by making a shallow copy and applying keyword overrides.

The copy returns a different object with the same top-level field values, except for the ones explicitly changed.

---

Solution

def clone(self, **changes) -> "Dashboard":
    cloned = copy(self)

    for field_name, value in changes.items():
        setattr(cloned, field_name, value)

    return cloned

Why copy.copy() works here

This exercise only checks top-level fields like title and owner.

copy.copy() creates a new Dashboard object whose top-level fields point to the same values.

Reassigning cloned.title = "UK Sales Dashboard" replaces the string reference on the clone, so the original is unaffected.

That is enough to pass exercise 1.

The next exercise shows where shallow copying breaks down.
