Quiz Question 1 of 5
In a polymorphic context, consider the following code snippet:
`class Shape: def area(self): return "Calculating area"
class Circle(Shape): def area(self): return "Calculating area of a circle"
class Square(Shape): def area(self): return "Calculating area of a square"
shapes = [Circle(), Square(), Shape()] result = [shape.area() for shape in shapes]`
Which of the following statements is true regarding the result of this list comprehension?
Choose the correct answer below:
-
A
The output list will contain
["Calculating area of a circle", "Calculating area of a square", "Calculating area"]based on the type of each object. -
B
The list comprehension will return
Nonefor each object because thearea()method does not return any value. -
C
The output list will contain
["Calculating area", "Calculating area", "Calculating area"]as polymorphism does not apply here. -
D
The list comprehension will raise an error because
Shapedoes not have a concrete implementation ofarea().
