title: python classes adding numbers
body: <p>I need to write a class, Numbers, with methods addNumbers and currentSum, that prints the current sum. Eg.:</p>
  
  <pre><code>numbers = Numbers()
  numbers.addNumber(3)
  numbers.addNumber(2)
  print numbers.currentSum()
  </code></pre>
  
  <p>should print 5</p>
  
  <p>I have made a class:</p>
  
  <pre><code>class Numbers:
      def __init__(self, numbers):
      self.numbers=addNumbers
      return numbers.currentSum()
  Numbers=Numbers()
  </code></pre>
  
  <p>A hint, anyone?</p>
