title: Zybook - paint challenge python
body: <p>Scenario: 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
  ____________________________________-</p>
  <pre><code>gallons_paint = 0.0
  
  wall_area = float(input())
  
  # Assign gallons_paint below
  
  ''' Your solution goes here '''
  
  print(gallons_paint)
  </code></pre>

  <p>I've been trying different combinations and I can't figure out how to get the float right.
  Any help would be appreciated! :)</p>
