What types of inheritance exist in object-oriented programming?

Single Inheritance: A class inherits from one parent class.

class Parent:
    pass

class Child(Parent): # Child class inherits from Parent
    pass

Multiple Inheritance: A class inherits from multiple parent classes.

class Parent1:
    pass

class Parent2:
    pass

class Child(Parent1, Parent2): # Child class inherits from Parent1 and Parent2
    pass

Multilevel Inheritance: A class inherits from another class, which in turn inherits from another class.

class Grandparent:
    pass

class Parent(Grandparent): # Parent inherits from Grandparent
    pass

class Child(Parent): # Child inherits from Parent
    pass

Hierarchical Inheritance: Multiple classes inherit from one parent class.

class Parent:
    pass

class Child1(Parent): # Child1 inherits from Parent
    pass

class Child2(Parent): # Child2 inherits from Parent
    pass

Hybrid Inheritance: A combination of two or more of the above types of inheritance.

class A:
    pass

class B(A): # Multilevel: B inherits from A
    pass

class C(A): # Hierarchical: C inherits from A
    pass

class D(B, C): # Multiple: D inherits from B and C
    pass
