Create Problem2.py''' 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, 89, ... By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.  '''  def fib(n):     total = 0     a, b = 0, 1     while b<n:         a, b = b, a + b         if (b%2==0):             total= total+ b     return total                 print fib(4000000)
