    Attributes of a class are function objects that define corresponding methods of its instances. They are used to implement access controls of the classes.
    Attributes of a class can also be accessed using the following built-in methods and functions :

    1. getattr() – This function is used to access the attribute of object.
    2. hasattr() – This function is used to check if an attribute exist or not.
    3. setattr() – This function is used to set an attribute. If the attribute does not exist, then it would be created.
    4. delattr() – This function is used to delete an attribute. If you are accessing the attribute after deleting it raises error “class has no attribute”.

    The following methods are explained with the example given below :

    class emp: 

        name='Harsh'

        salary='25000'

        def show(self): 

            print (self.name) 

            print (self.salary) 

    e1 = emp() 

    print (getattr(e1,'name')) 

    print (hasattr(e1,'name')) 

    setattr(e1,'height',152

    print (getattr(e1,'height')) 

    delattr(emp,'salary'

    Output :

    Harsh
    True
    152

    Static methods : A static method is a method[member function] that don’t use argument self at all. To declare a static method, proceed it with the statement “@staticmethod”.

    class test: 

        @staticmethod

        def square(x): 

            test.result = x*

    t1=test() 

    t2 = test() 

    t1.square(2

    print (t1.result) 

    t2.square(3

    print (t2.result) 

    print (t1.result) 

    Output :

    4
    9
    9

    Accessing attributes and methods of one class in another class

    Accessing attributes and methods of one class in another class is done by passing the object of one class to another.
    Explained with the example given below :

    class ClassA(): 

        def __init__(self): 

            self.var1 = 1

            self.var2 = 2

        def methodA(self): 

            self.var1 = self.var1 + self.var2 

            return self.var1 

    class ClassB(ClassA): 

        def __init__(self, class_a): 

            self.var1 = class_a.var1 

            self.var2 = class_a.var2 

    object1 = ClassA() 

    summ = object1.methodA() 

    print (summ) 

    object2 = ClassB(object1) 

    print( object2.var1)

    print (object2.var2) 

    Output :

    3
    3
    2

    What is attribute in Python?

    Class and Instance Attributes in Python To give a basic definition of both terms, class attributes are class variables that are inherited by every object of a class. The value of class attributes remain the same for every new object.

    What is a method in Python?

    A method is a function that “belongs to” an object. (In Python, the term method is not unique to class instances: other object types can have methods as well. For example, list objects have methods called append, insert, remove, sort, and so on.

    What is attribute and method of a class?

    Any variable that is bound in a class is a class attribute . Any function defined within a class is a method . Methods receive an instance of the class, conventionally called self , as the first argument.

    What is attribute and method in OOP?

    A Class can be a parent of many objects while an object is a child of a class. Inside the class closure{} variables are called attributes(data members) and the functions inside that get or set values are called methods.
