1. Predict the output of this program. ``

python
def describe(value):
    match value:
        case int(i) if i < 0:
            return f"negative {i}"
        case int(i):
            return f"integer {i}"
        case str(s):
            return f"text of length {len(s)}"
        case _:
            return f"other: {type(value).__name__}"

print(describe(-3))
print(describe("abc"))
print(describe(2.5))

``

integer -3 text of length 3 other: floatnegative -3 text of length 3 other: 2.5negative -3 abc other: floatnegative -3 text of length 3 other: float

2. Predict the output of this program. ``

python
import copy

class Animal:
    def __init__(self, name):
        self.name = name

    def speak(self):
        return f"{self.name} makes a sound"

class Dog(Animal):
    def __init__(self, name, toy):
        super().__init__(name)
        self.toy = toy

    def speak(self):
        return f"{self.name} barks"

rex = Dog("Rex", "ball")
plain = Animal(rex.name)
same = rex
print(plain.speak())
print(same.speak())
print(same is rex)
clone = copy.copy(rex)
print(type(clone).__name__, clone.toy)

``

Rex barks Rex barks True Dog ballRex makes a sound Rex barks True Dog ballRex makes a sound Rex makes a sound False Dog ballRex makes a sound Rex barks True Dog None

3. A variable d holds Dog(), where Dog is a subclass of Animal. Which of these lines prints False?

print(isinstance(d, Animal))print(isinstance(d, Dog))print(type(d) is Animal)print(isinstance(d, object))

4. copy.copy makes a new object whose attributes point to the same objects as the original. The objects inside those attributes are not copied. The lesson calls this kind of copy a ____ copy.

Type your answer.

5. Which exception does Python raise for this code? ``

python
value = None
value.speak()

``

Type your answer.

Slicing and the object class
