    今天第一次看到欧拉计划,感觉很兴奋,决定挑战一下。 什么是欧拉计划? 欧拉计划是一系列挑战数学、计算机编程的问题。 第一题: If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.Find the sum of all the multiples of 3 or 5 below 1000. 示例:

    def divid(x): return x % 3 == 0 or x % 5 ==0 sum = 0 for num in filter(divid, range(1,1000)): sum += num print(sum) 233168
