Fill in the blanks to make the print_prime_factors function print all the prime factors of a number prime factor is a number tha

Question:

The function is_positive should yield True if the supplied number is positive; otherwise, it gives None. Can you fill in the blanks accordingly?

def is_positive(number):

       if  _____ :

           return _____

Answer:

def is_positive(number):

   if (number > 0):

       return True

  else:

       return "None"

---------------------------------------------------------------------------------

Code Test and Sample Output:

print(is_positive(6))

>> True

print(is_positive(-7))

>> None

----------------------------------------------------------------------------------

Explanation:

This segment of code is composed in Python.

To explain it further, let's break down the content of each line;

Line 1: Creates a function identified as is_positive which takes in a variable number.i.e

def is_positive(number):

Line 2: Evaluates if the given number is positive; a number qualifies as positive if it exceeds zero. i.e

if (number > 0):

Line 3: Produces a boolean result of True when the input number is positive. i.e

return True

Line 4: Initiates the else block to be executed in case the input number isn’t positive. i.e

else:

Line 5: Returns the string "None" when the number is not positive. i.e

return "None"

When combined, this results in;

===============================

def is_positive(number):

   if (number > 0):

       return True

   else:

       return "None"

================================

An instance test for the code provided an argument of 6 and -7, resulting in True and None respectively. i.e

print(is_positive(6))   = True

print(is_positive(-7))  = None

Answer:

public void printAll(){ // member function petAll()

   super.printAll(); //  invokes printAll() method from the superclass (base class) AnimalData using the super keyword

   System.out.print(", ID: " + idNum);} // displays the ID saved in the idNum field of the PetData class

Explanation:

This is the full PetData class:

public class PetData extends AnimalData { //

private int idNum;

public void setID(int petID) {

idNum = petID; }

// FIXME: Implement printAll() member method

/* Your solution goes here */

public void printAll(){

   super.printAll();

   System.out.print(", ID: " + idNum);}  }

The PetData class is a subclass that inherits from the base class AnimalData.

This class contains a private field, idNum, which is designated for storing the ID value.

It includes a method setID which takes petID as a parameter that corresponds to idNum. Essentially, this acts as a mutator to set the user ID.

Additionally, there is a printAll() method that makes use of the super keyword to call the printAll() method from the base class, AnimalData.

Using super refers to objects of the base class.

Here, the super keyword is utilized with the method name from the subclass PetData to avoid confusion, as both AnimalData and PetData have a method named printAll().

During the main() method, users will enter values for userName, UserAge, and UserID. For example, if the user inputs Fluffy as the name, 5 as the age, and 4444 as the userID. Then, calling userPet.printAll(); will execute the printAll() method from the PetData class since userPet is an instance of PetData.

When this method executes, it will call the printAll() of AnimalData class which outputs the Name and Age, while printAll() of PetData prints the ID. Consequently, the resulting output will be:

Name: Fluffy, Age: 5, ID: 4444
