title: Output list of even Fibonacci numbers in Euler prob 2 with Python 2.75
body: <p>How to output results in list form (with code not manually) on Python 2.75.
  Instead of solving just for the sum I inserted <code>print i</code> then sum and got the numbers visible (11 of them). Please help with this very basic question. Thank you.</p>
  
  <pre><code>##Even Fibonacci numbers Problem 2
  ##Each new term in the Fibonacci sequence is generated by adding the previous two terms.
  ##By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55...
  ##By considering the terms in the Fibonacci sequence whose values do not exceed
  ##four million, find the sum of the even-valued terms.
  import fibo
  sum = 0
  a = fibo.fib2(4000000)
  for i in a:
      if i%2==0:
          print i
          sum += i
  print "the sum of these even Fibonacci numbers = "
  print sum
