Question 1 : How to check the type of the class object?

class car:
    def __init__(self, name, brand):
        self.name = name
        self.brand = brand
        
class bus:
    def __init__(self, name, brand):
        self.name = name
        self.brand = brand
    
a3 = car("Q3", "Audi")
v9 = bus("V9400", "Volvo")

print(type(a3))
print(type(v9))

Output:

<class '__main__.car'>
<class '__main__.bus'>

Question 2 : How to check if an object is the instance of the class?

class car:
    def __init__(self, name, brand):
        self.name = name
        self.brand = brand
        
class bus:
    def __init__(self, name, brand):
        self.name = name
        self.brand = brand
    
a3 = car("Q3", "Audi")
v9 = bus("V9400", "Volvo")

print(isinstance(a3, car))
print(isinstance(v9, car))

Output:

True
False

Question 3 : Define a common class attribute for all the classes.

class car:
    brand = "Audi"
    
    def __init__(self, name, engine):
        self.name = name
        self.engine = engine

q5 = car("Q5", "Pertol")
d6 = car("D6", "Diesel")

print(q5.brand)
print(q5.name)

print(d6.brand)
print(d6.engine)

Output:
