A method that only the child class has

The event post class Event inherits from the post class Post. Predict the output without running the code.

Code

class Post:
    def __init__(self, author):
        self.author = author
        self.likes = 0

    def like(self):
        self.likes += 1

    def __str__(self):
        return f"{self.author}: {self.likes} likes"

class Event(Post):
    def boost(self):
        self.like()
        self.like()

e = Event("mina")
e.boost()
e.like()
print(e)
p = Post("jun")
p.boost()
print(p)
