I believe the answers would be A and B. Because you have to fulfill  Chantelle's wishes and you have to access their data. Which I am guessing would require a database backup.  

I hope this helps.

CaHeK987 [17]

Answer:

The answer to this question can be given as:

Program:

#define class.

class PersonInfo:

   def __init__(self):  #constructor

       self.num_kids = 0

   def inc_num_kids(self):   #define function inc_num_kids()

       self.num_kids = self.num_kids + 1  

       return self.num_kids  #return value.

p= PersonInfo()      # creating object  

print('Kids:', p.num_kids)  #print value

p.inc_num_kids() #call function

print('New baby, kids now:', p.num_kids) #print value

Output:

Kids: 0

New baby, kids now: 1

Explanation:

The description of the above python program as follows:

  • In this program firstly we define the class that is PersonInfo. In this class we define the constructor that is def __init__() and one function that is  def inc_num_kids().
  • The constructor is called automatically when the class object is created. In this constructor, we use the self as a parameter that is used to access variables that belong to class.
  • In the constructor, we define the variable that is "num_kids". We assign value to a variable that is "0" and use the self for holding reference to the variable.
  • Then we define the function. In this function, we increment the value of the variable by 1 and return its value.
  • Then we create a class object that is p and call the function and print its value.
