Question

PLEASE YOU PYTHON 3 TO SOLVE! THANKS!
Example 1 Design a class named Information that holds the following personal data: .name, age, address (this attribute has a default value of “unknown"), and phone number. . All the attributes are defined as private. • Write appropriate accessor and mutator methods. • Complete the definition of the str_ method, such that it displays each Information object's data in the following format: name: "Sarah Jones” – age: “21” – address: “2000 Simcoe North” • Create two instances of the class. • Create a function named display_info that accepts an Information object as an argument and display name, address, age, and phone number for the object.

Answer 1

Answer to above question is-

CODE:

# information class is created
class information:
# constructor method to initialize the class variables
# private variables can be made by adding __ at the starting of variable name
def __init__(self,name,age,phoneNumber,address='uknown'):
self.__name = name #private variable
self.__age = age #private variable
self.__address = address #private variable
self.__phoneNumber = phoneNumber #private variable
  
#defining accessor methods
# class method to get name of the person
def get_name(self):
return self.__name
# class method to get age of the person
def get_age(self):
return self.__age
# class method to get address of the person
def get_address(self):
return self.__address
# class method to get phone Number of the person
def get_phoneNumber(self):
return self.__phoneNumber
  
# defining mutator methods\
# class method to change name of a person
def set_name(self,a):
self.__name =a
# class method to change age of a person
def set_age(self,a):
self.__age =a
# class method to change address of a person
def set_address(self,a):
self.__address =a
# class method to change phoneNumber of a person
def set_phoneNumber(self,a):
self.__phoneNumber =a   
# class method for string representation
def __str__(self):
return 'name:"{}"-age:"{}"-address:"{}"-phone number:"{}"'.format(self.__name,self.__age,self.__address,self.__phoneNumber)

# method to display information of person
# this method accepts object as argument
def display_info(object):
print(object)
# creating two instances of class information
n1 = information('abc',22,555555666,'us')
n2 = information('xyz',27,666555888)
# calling display_info method to show person information
display_info(n1)
display_info(n2)
# calling set_name method to change name of person
n1.set_name('pqr')
display_info(n1)
# calling set_address method to change address of a person
n2.set_address('uk')
display_info(n2)

print("phoneNumber of person {} is {}".format(1,n1.get_phoneNumber()))
print("age of person {} is {} ".format(2,n2.get_age()))

Output:
