title: Excluding 0's from calculations
body: <p>Hi I have been asked to write a program that will keep asking the user for numbers. The average should be given to 2 decimal places and if a 0 is entered it shouldnt be included in the calculation of the average.</p>
  
  <p>so far I have this:</p>
  
  <pre><code>data = input()
  numbers = []
  while True: 
      data = input()
      if data == "":
          break
      numbers.append(float(data))
  count = len(numbers)
  if count &gt; 0: 
      newsum = sum(numbers)
      average = newsum / float(count)
  
  print("The average is {}".format(average))
  </code></pre>
  
  <p>Dumb question but how do you ensure the 0's arent considered in the calculation?</p>
