class User:

name = ""

phone = ""

email = ""

def __init__(self, name="", phone="", email=""):

print ("User class is created...")

self.name = name

self.phone = phone

self.email = email

def __ne__(self, other):

if (self.name != other.name) or (self.phone != other.phone) or (self.email != other.email):

return True

else:

return False

def __eq__(self, other):

if (self.name == other.name) and (self.phone == other.phone) and (self.email == other.email):

return True

else:

return False

def __str__(self):

return self.name + "," + self.email +"," +self.phone

user1 = User(name="kresna", phone="7501234", email="kresnagaluh@example.com")

user2 = User(name="kresna", phone="7501234", email="kresnagaluh@example.com")

user3 = User(name="toni", phone="7504357", email="toni@example.com")

print (user1)

print (user2)

print (user3)

print (user1 == user2)

print (user1 == user3)

print (user1 != user2)

print (user1 != user3)
