Using Classes

This problem relates to the pre-loaded class Person.

Using the Person class, write a function print_friend_info(person) which accepts a single argument, of type Person, and:

• prints out their name
• prints out their age
• if the person has any friends, prints 'Friends with {name}'

Write a function create_fry() which returns a Person instance representing Fry. Fry is 25 and his full name is 'Philip J. Fry'

Write a function make_friends(person_one, person_two) which sets each argument as the friend of the other.

class Person(object):
def __init__(self, name, age, gender):
"""Construct a person object given their name, age and gender

Parameters:
name(str): The name of the person
age(int): The age of the person
gender(str): Either 'M' or 'F' for male or female
  
"""

self._name = name
self._age = age
self._gender = gender
self._friend = None

def __eq__(self, person):
return str(self) == str(person)

def __str__(self):
if self._gender == 'M':
title = 'Mr'
elif self._gender == 'F':
title = 'Miss'
else:
title = 'Ms'

return title + ' ' + self._name + ' ' + str(self._age)

def __repr__(self):
return 'Person: ' + str(self)

def get_name(self):
"""
(str) Return the name
  
"""
return self._name

def get_age(self):
"""
(int) Return the age
  
"""
return self._age

def get_gender(self):
"""
(str) Return the gender
  
"""
return self._gender

def set_friend(self, friend):
self._friend = friend

def get_friend(self):
"""
(Person) Return the friend
  
"""
return self._friend
