The following code is written in Java. It creates the loop as requested and validates the information provided before continuing, if the information is invalid it prints "Invalid Information to the screen" and asks the user to enter the information again. Finally, outputing all the requested information at the end of the program. The code has been tested and the output can be seen in the attached image below.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       int totalValues = 0;

       int totalTaxes = 0;

       int count = 0;

       while(true) {

           int lotNumber, value;

           double tax;

           System.out.println("Would you like to add an Entry: 1=Yes 0=No");

           int answer = in.nextInt();

           if (answer == 1) {

               System.out.println("Please enter lot number: ");

               lotNumber = in.nextInt();

               if ((lotNumber >= 0) && (lotNumber <= 999999)) {

                   System.out.println("Please enter assessed value: ");

                   value = in.nextInt();

                   tax = value * 0.05;

                   System.out.println("Lot Number: " + lotNumber);

                   System.out.println("Property Value: " + value);

                   System.out.println("Property Tax: " + tax);

                   totalTaxes += tax;

                   totalValues += value;

                   count += 1;

               } else {

                   System.out.println("Invalid Lot Number");

               }

           } else {

               break;

           }

       }

       int average = totalTaxes / count;

       System.out.println("Total Property Values: " + totalValues);

       System.out.println("Total Property Taxes: " + totalTaxes);

       System.out.println("Average Property Tax" + average);

   }

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
sdas [7]

Answer:

The modified program in Python is as follows:

import math

paint_colors = {'red': 35,'blue': 25,'green': 23}

wall_height = int(input('Enter wall height (feet):\n'))

wall_width = int(input('Enter wall width (feet):\n'))

area = wall_height*wall_width

print('Wall area:',area,'square feet')

paint_needed = area/350.0

print('Paint needed: {:.2f} gallons'.format(paint_needed))

print('Cans needed:',round(paint_needed),'can(s)')

color = input("Choose a color to paint the wall: ")

print("Cost of purchasing", color, "paint: $",paint_colors[color])

Explanation:

The italicized are given from the question [unchanged]

<em>import math</em>

<em> paint_colors = {'red': 35,'blue': 25,'green': 23} </em>

<em>wall_height = int(input('Enter wall height (feet):\n')) </em>

This gets input for width

wall_width = int(input('Enter wall width (feet):\n'))

Calculate the wall area

area = wall_height*wall_width

Print the calculated wall area

print('Wall area:',area,'square feet')

Calculate the amount of paint needed

paint_needed = area/350.0

Print the amount of paint needed to 2 decimal places

print('Paint needed: {:.2f} gallons'.format(paint_needed))

Print the amount of can needed to nearest integer

print('Cans needed:',round(paint_needed),'can(s)')

Prompt user for color of paint [here, we assume the user input is correct]

color = input("Choose a color to paint the wall: ")

Prints the corresponding amount for the color

print("Cost of purchasing", color, "paint: $",paint_colors[color])
