Python Question:

(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 2 points, so 4 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 2 points, so 6 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 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)

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

 

Here is the Main.py template
