🟦 What is Inheritance?

Inheritance allows one class (child) to acquire properties and methods of another class (parent).
---

🔸 Types of Inheritance:

1. Single Inheritance – One child, one parent
2. Multiple Inheritance – Child inherits from multiple parents
3. Multilevel Inheritance – Chain of inheritance
4. Hierarchical Inheritance – One parent, multiple children
5. Hybrid Inheritance – Combination of multiple types
---

✅ Syntax:

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

class Child(Parent):
def say_hi(self):
print("Hi from Child")
---

🔁 Using Inherited Methods:

c = Child()
c.greet() # Inherited from Parent
c.say_hi() # Defined in Child
---

🔄 Method Overriding:

Child can override a parent method:

class Child(Parent):
def greet(self):
print("Hello from Child") # Overrides Parent.greet
---

🔹 super() Function:

Used to call the parent class’s methods/constructor.

class Parent:
def __init__(self):
print("Parent init")

class Child(Parent):
def __init__(self):
super().__init__() # Calls Parent's __init__
print("Child init")
