Question

in python please

(1) Prompt the user to input a wall's height and width. Calculate and output the wall's area (integer). (Submit for 2 points).

Enter wall height (feet):
12
Enter wall width (feet):
15
Wall area: 180 square feet

(2) Extend to also calculate and output the amount of paint in gallons needed to paint the wall (floating point). Assume a gallon of paint covers 350 square feet. Store this value in a variable. Output the amount of paint needed using the %f conversion specifier. (Submit for 3 points, so 5 points total).

Enter wall height (feet):
12
Enter wall width (feet):
15
Wall area: 180 square feet
Paint needed: 0.514286 gallons

(3) Extend to also calculate and output the number of 1 gallon cans needed to paint the wall. Hint: Use a math function to round up to the nearest gallon. (Submit for 3 points, so 8 points total).

Enter wall height (feet):
12
Enter wall width (feet):
15
Wall area: 180 square feet
Paint needed: 0.514286 gallons
Cans needed: 1 can(s)

(4) Extend by prompting the user for a color they want to paint the walls. Calculate and output the total cost of the paint cans depending on which color is chosen. Hint: Use a dictionary to associate each paint color with its respective cost. Red paint costs $35 per gallon can, blue paint costs $25 per gallon can, and green paint costs $23 per gallon can. (Submit for 2 points, so 10 points total).

Enter wall height (feet):
12
Enter wall width (feet):
15
Wall area: 180 square feet
Paint needed: 0.514286 gallons
Cans needed: 1 can(s)

Choose a color to paint the wall:
red
Cost of purchasing red paint:
$35

Answer 1

import math
paintColors = {
    'red': 35,
    'blue': 25,
    'green':23
}

wallHeight = float(input("Enter wall height (feet):\n"))
wallWidth = float(input("Enter wall width (feet):\n"))
area = wallHeight*wallWidth
print("Wall area:",int(area),"square feet")
paintNeeded = area/350
print("Paint needed: %f gallons"%paintNeeded)
print("Cans needed:",math.ceil(paintNeeded),"can(s)")
color = input("\nChoose a color to paint the wall:\n")
print("Cost of purchasing",color,"paint: $",end="")
print(paintColors[color])
