πŸš€ How to Call a Parent Class Method from a Child Class in Python?

Let's dive in and answer this popular interview-style question! πŸ‘¨β€πŸ’»πŸ‘©β€πŸ’»

---

πŸ”₯ Question:
How can you call a method of the parent class from within a method of a child class?

---

βœ… Correct Answer:
Option 1: Using the super() function

πŸ‘‰ Why?
- In Python, super() is the standard way to access methods and properties of a parent class from inside a child class.
- It's clean, elegant, and also supports multiple inheritance properly.

---
βœ… Quick Example:

class Parent:
def greet(self):
print("Hello from Parent!")

class Child(Parent):
def greet(self):
print("Hello from Child!")
super().greet() # Calling parent class method

# Create an instance
child = Child()
child.greet()


πŸ›  Output:
Hello from Child!
Hello from Parent!


---

πŸ”₯ Let's Review Other Options:
- Option 2: Directly calling parent method (like Parent.greet(self)) is possible but not recommended. It tightly couples the child to a specific parent class name.
- Option 3: Creating an instance of the parent class is incorrect; you should not create a new parent object.
- Option 4: parent_method() syntax without reference is invalid.

---

🎯 Conclusion:
βœ… Always use super() inside child classes to call parent class methods β€” it's the Pythonic way! 🐍✨

πŸ”₯ Simple Explanation:
- In Python, we use the class keyword to define any class (whether it's a base class or a child class).
- There’s no keyword like inherit, superclass, or parent in Python.
- inherit means "to inherit," but it's not a Python keyword.
- superclass and parent are just concepts, not keywords.

---

βœ… A Simple Example:

class Animal:
pass

class Dog(Animal):
pass


πŸ”Ή Here:
- Animal is a base class (or parent class).
- Dog is a child class that inherits from Animal.

And for both, the class keyword is used! 🎯

---
🎯 Conclusion:
βœ… So, always use class to define any class in Python (whether it's a parent or child class).
