## Project Euler Challenge #2 : Fibonacci Sums

### Thursday, July 24, 2014

Another straightforward challenge: find the sum of all even numbers in the Fibonacci sequence less than four million.

def even_fib_sum(limit = 10): num = 2 pre = 1 tot = 2 while num < limit: num += pre pre = num - pre if num % 2 == 0: tot += num return tot

Yeah, yawn.
