________ platforms automate tasks such as setting up a newly composed application such as a web service or linking to other applications.

The is_positive function should return True if the number received is positive, otherwise it returns None. Can you fill in the gaps to make that happen?

def is_positive(number):

       if  _____ :

           return _____

def is_positive(number):

   if (number > 0):

       return True

  else:

       return "None"

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

print(is_positive(6))

>> True

print(is_positive(-7))

>> None

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

The code above has been written in Python.

Now, let's explain each of the lines of the code;

Line 1: defines a function called is_positive which takes in a parameter number. i.e

def is_positive(number):

Line 2: checks if the number, supplied as parameter to the function, is positive. A number is positive if it is greater than zero. i.e

if (number > 0):

Line 3: returns a boolean value True if the number is positive. i.e

return True

Line 4: defines the beginning of the else block that is executed if the number is not positive. i.e

else:

Line 5: returns a string value "None" if the number is not positive. i.e

return "None"

All of these put together gives;

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

def is_positive(number):

   if (number > 0):

       return True

   else:

       return "None"

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

An example test of the code has also been given where the function was been called with an argument value of 6 and -7. The results were True and None respectively. i.e

print(is_positive(6))   = True

print(is_positive(-7))  = None

Following are the python program to check input number is positive or negative:

def is_positive(n):#defining the method is_positive that takes one variable in parameter

   if (n > 0):#defining if block that check input number is positive

       return True#return boolean value that is True

   else:#else block

      return "None"#return string value

n=int(input("Enter number: "))#defining n variable that input a number

print(is_positive(n))#using print method that calls and prints method return value

Answer:

This is written in C++

Check comments for explanations

Program starts here

#include<iostream>

#include<string>

using namespace std;

//The function get_ap_terms begins here

string get_ap_terms(int a, int d, int size_tn)

{  

// This line initializes the expected string to empty string

string result = "";

//The for iteration loops through the number of terms the function is expected to return

for(int i = 1; i<= size_tn;i++)

{

//This line checks if the loop is less than the number of  terms    

if(i < size_tn)

  {

//This string gets the current term of the progression

   result+=to_string(a)+ ", ";

//This line calculates the next term

   a+=d;  

  }

  else

  {

//This line calculates the last term

   result+=to_string(a);

  }

}

//This line returns the string containing the first n terms of the arithmetic progression

return result;

}

//The main function starts here

int main()

{

//This line declares the first term (a), the common difference (d) and the number of terms (size_tn)

int a,d,size_tn;

//This line prompts the user for the first term

cout<<"First Term: ";

//This line gets the first term

cin>>a;

//This line prompts the user for the common difference

cout<<"Common Difference: ";

//This line gets the common difference

cin>>d;

//This line prompts the user for number of terms

cout<<"Number of Terms: ";

//This line gets the number of terms

cin>>size_tn;

//This line calls the function to print the string containing the first n terms

cout<<get_ap_terms(a, d, size_tn);

return 0;

}

//Program ends here
