# Operator overloading in python done by using something called as maigc/dundard methods

# dundard methods are defined with '__' operators. e.g. __init__ method is also dundard method

# There are two special methods that we can define in code __repr__ and __str__

# __repr__ method will show object creation of class and it is used for debugging

# __str__ method will show string representation of employee object, it will print employee in more readable form

class Employee:

raise_amount = 1.04 # are a class variables

def __init__(self, first, last, pay):

self.first = first

self.last = last

self.pay = pay

self.email = first + '.' + last + '@email.com'

def full_name(self):

return '{} {}'.format(self.first, self.last)

def apply_raise(self):

self.pay = int(self.pay * self.raise_amount)

def __repr__(self):

return "Employee({}, {}, {})".format(self.first, self.last, self.pay)

def __str__(self):

return "{} - {}".format(self.full_name(), self.email)

# we are adding dundar __add__ method for Employee class which will tell combined salary of two employees

def __add__(self, other):

return self.pay + other.pay

# below e1 and e2 are called instances of class employee

e1 = Employee('sheldon', 'cooper', 5000)

e2 = Employee('Prathamesh', 'rahate', 6000)

#print(e1)

#print(e2)

# other way to call repr and str methods explicitely

print(e1.__repr__())

print(e1.__str__())

# calling dundar add method on e1 and e2

print(e1 + e2)
