CHALLENGE ACTIVITY 3.2.1: Gallons of paint needed to paint walls. Finish the program to compute how many gallons of paint are needed to cover the given square feet of walls. Assume 1 gallon can cover 350.0 square feet. So gallons = the square feet divided by 350,0. If the input is 250.0, the output should be: 0.714285714286 1 gallons_paint - 0.0 3 wall_area - float(input ) S # Assign gallons_paint below 7 Your solution goes here 9 print(gallons paint)
