Class Method In OOP

# Class Method - Which takes class as argument #

class Employee:
    no_of_leaves = 8 # class variable

    # Constructer = Use to initialize objects
    def __init__(self,name,salary,role,workinghrs):
        self.name = name
        self.salary = salary
        self.role = role
        self.workinghrs = workinghrs

    # Method
    def printdetails(self):
        return f"The Name is {self.name},Salary is {self.salary},Role is {self.role} and Working Hours are {self.workinghrs}"

    @classmethod  # Decorator #
    def change_leaves(cls,newleaves):
        cls.no_of_leaves = newleaves

emp1 = Employee("EMP1",99999,"Senior Manager",11) # First Object
emp2 = Employee("EMP2",88888,"Manager",12) # Second Object

emp1.change_leaves(19)    # Class variable is changed by the object with the help of Class Method #
Employee.change_leaves(29)  # Changed by the class #
emp2.change_leaves(9)   # Again changed by the object #
print(emp1.no_of_leaves)
