Explain how to overload constructors (or methods) in Python.

• _init__ () is a first method defined in a class. 
• when an instance of a class is created, python calls __init__() to initialize the attribute of the object.

Following example demonstrate further:

class Employee:

      def __init__(self, name, empCode,pay):

            self.name=name

            self.empCode=empCode

            self.pay=pay

e1 = Employee("Sarah",99,30000.00)

e2 = Employee("Asrar",100,60000.00)

print("Employee Details:")

print(" Name:",e1.name,"Code:", e1.empCode,"Pay:", e1.pay)

print(" Name:",e2.name,"Code:", e2.empCode,"Pay:", e2.pay)

---------------------------------------------------------------

Output

Employee Details:

(' Name:', 'Sarah', 'Code:', 99, 'Pay:', 30000.0)

(' Name:', 'Asrar', 'Code:', 100, 'Pay:', 60000.0)
