Hi, can I make a class with a lot of classes in the inside of this one? Its the only way I think one can accomplished polymorphism. Also, If I call a superclass that has a lot of subclasses, will it “call” only the superclass or will it call the superclass, I mean by this if I will only be able to use modify my data with the method inside the superclass, or if I call my superclass will I be able to use the methods inside that superclass?
How can I create a polymorphism of classes?
That would not be the way to go.
based on the explanation in this lesson:
The following example qualifies as polymorphism:
class A:
def abc(self):
print('hello a')
class B:
def abc(self):
print('hello b')
class C:
def abc(self):
print('hello c')
a = A()
a.abc()
b = B()
b.abc()
c = C()
c.abc()
the same method does different things on different classes. Same for the + (see example in the lesson).
this is known as MRO, here is a an article:
that is a bit too much for a single forum post.
I have made an example, that is more practical:
class Circle:
def __init__(self, radius):
self.pi = 3.1415
self.radius = radius
def get_area(self):
return self.radius ** 2 * self.pi
class Square:
def __init__(self, length_a):
self.length_a = length_a
def get_area(self):
return self.length_a ** 2
class Rectangle(Square):
def __init__(self, length_a, length_b):
super().__init__(length_a)
self.length_b = length_b
def get_area(self):
return self.length_a * self.length_b
