[Python] OOP

### Class
class Human:
    """
    This is Human prototype
    Created by GOD
    """

    def __init__(self, name, color):
        self.name, self.color = name, color

    def greet(self):
        print("Hello, I'm Human, created by GOD")
        print(f"\tMy Name is: {self.name}")
        print(f"\tMy Color is: {self.color}")

john = Human("Jonny Deep", "White")
john.greet()

Đây là output
