Can you call a class in another class?

Question

What I mean by this is for example lets take the classes from routine practice 19. If we wanted to call the class Coins in the class Food, is that a possibility?

Answer 1

There is a concept in OOD called Inheritance. In Python, you can have a derived class - a class created or derived from another existing class. It inherits all the methods and properties from another class.

# Creating a Base class 
class Base: 
  
    # Declaring public method
    def fun(self):
        print("Public method")
  
    # Declaring private method
    def __fun(self):
        print("Private method")
  
# Creating a derived class 
class Derived(Base): 
    def __init__(self): 
          
        # Calling constructor of 
        # Base class 
        Base.__init__(self) 
          
    def call_public(self):
          
        # Calling public method of base class
        print("\nInside derived class")
        self.fun()
          
    def call_private(self):
          
        # Calling private method of base class
        self.__fun()
  
# Driver code 
obj1 = Base()
  
# Calling public method
obj1.fun()
  
obj2 = Derived()
obj2.call_public()
