Classes are user defined data structures (contrast with primitive data types-Integers,Float,Strings,Boolean) . It is also blueprint for creating many objects each with custom values. Let's begin with creating a car class without any details :

class Car:
        pass

Now let's add name , color as we expect real world Sedan car to have one through class constructor _init_ :

class Car:
        car_type = "Sedan"          #class attribute - common to all objects.
        def __init__(self, name, color):
                self.name = name    #instance attribute -each instance may have different value.
                self.color = color  #instance attribute -each instance may have different value.

Creating a particular instance for a red Honda City.

obj1 = Car("Honda City","Red")

Creating another instance for a blue Maruti Dzire.

obj2 = Car("Maruti Dzire","Blue")
