Finally a proper tutorial. For some reason other RU-vidrs act like they can explain this topic in 5 minutes. While in reality this is a complex topic especially for beginners. So, in those 5 minute tutorials you might have a bit of a grasp of what you're doing, but you're still clueless when you are on your own. Thanks for the tutorial! It was very informative!

Hi! Thanks for such a detailed lecture on OOP concepts using python. I found it really useful and wanted to say you thanks for all the efforts you put. Because earlier I got just very abstract level touch of classes but concepts like inheritance, class/static variables, instance variables, Class Methods, Instance Methods, Static Methods, Polymorphism, Duck typing, Operator overloading, Method Overloading techniques in Python and method Overriding. I learned a lot and really wanted to say you thanks for such detailed and in depth lecture which actually was different from others available on RU-vid and was very informative.

@401anil 4 года назад

Hi Naveen, I am able to see the change of class variable while changing using object instead of class. Is this expected? Code: class Car: # Whatever variables defined here are called class variables wheels = 4 mirrors = 3 def __init__(self): # Whatever variables defined here are called instance variable self.company = "Renault" self.milage = 20 self.gear = "Automatic" car1 = Car() car2 = Car() print(car1.wheels, car1.company, car1.milage, car1.gear) print(car2.wheels, car2.company, car2.milage, car2.gear) car1.company = "BMW" car2.company = "Maruti" car2.gear = "Manual" print(car1.wheels, car1.company, car1.milage, car1.gear) print(car2.wheels, car2.company, car2.milage, car2.gear) car1.wheels = 5 print(car1.wheels, car1.company, car1.milage, car1.gear) print(car2.wheels, car2.company, car2.milage, car2.gear) Output: (4, 'Renault', 20, 'Automatic') (4, 'Renault', 20, 'Automatic') (4, 'BMW', 20, 'Automatic') (4, 'Maruti', 20, 'Manual') (5, 'BMW', 20, 'Automatic') (4, 'Maruti', 20, 'Manual')

@kiranpdas 4 года назад

Anil A Yes, you can change the value of class variable using the object, but that won’t change the value of the variable for other objects. As in your example, the wheels of car1 was changed to 5 but that of car2 is still 4 and will be 4 for the class as well as any other object you create.

@hrittickdebnath1568 5 лет назад

sir, what is encapsulation in Python programming.

@mohammedistiaqhossain2476 2 года назад

Encapsulation means that other classes and the main program cannot access the variables and classes of the object that has been created. For example: class X: a = 10 def __init__(self): self.b = 9 @classmethod def fart(cls): print("pfffft") ' ' ' Now to print the variable a, you cannot just say print(a). You have to say print(X.a). Similarly, you cannot access the fart() function without addressing the class X. So you would have to say X.fart() to use the fart() function. This is what encapsulation is. All the variables and functions are encapsulated in a class that cannot be accessed without addressing the class. This prevents the variables and functions from being altered within the class, so encapsulation is a very important feature of OOP. ' ' '

@sunnykumar-yl9fe 3 года назад

at 56:16 where you have defined class inside class calling the instance as such will fail , if your init method inside class has arguments ( TypeError: __init__() missing required positional arguments) .Rather a better way of calling would be s1=..() .This works universally
