用 js 遍历数组，然后调用 python 脚本处理数组元素，但得到的结果却是乱序的 at 2018年02月26日

1.问题二没有出现了，谢谢哈;
2 .嗯，是我表述的不清楚。
就是我将 py_test.py 脚本改成这样的话：
# py_test.py import sys script,value = sys.argv print value然后会按照 js 脚本中的变量 list 中元素的顺序输出：
1 What makes Rails so great? 2 do you love me still ? 3 The Ruby on Rails Tutorial is designed to give you a thorough introduction to web application developmentntrepreneur. 4 of course i still love you .而不是随机的顺序。像这样：

谢谢。应该这问题对于各位的确太简单了
,但我感觉想要相处画这张流程图的思路好难啊
我想看看用流程图描述这个算法，比用自然语言等方式描述更便于计算。 -

谢谢，问题解决了。但感觉这个流程图并不适合在读代码的时候在脑子里想出来，然后按照流程图计算。反而用自然语言描述这个算法后比较容易计算. 感谢

流程图是下面这样:
虽然觉得很奇怪感觉，这个流程图和我计算的过程并不相同。 -

你的这个代码风格是使用 if modifier 和 return 做的，非常简洁漂亮，但是表示的算法还是和原来的代码一样，我画不出来😂

我知道这道的基本条件是 number < 2，给我一个数值我也能算出来结果，可是我画不出流程图. 能麻烦你能帮我画个草图吗？
