我正在绘制公寓中的Internet连接图,并且有用于上传和下载速度以及时间的数据。我有所有这些变量的数据列表,但是我需要将自己的时间列表与其自身相加。也就是说,我需要[a,a + b,a + b + c,a + b + c + d,a + b + c + d + e,...]等。
我的带有时间的列表仅以10到20秒为间隔,我需要一种将它们加在一起并制成如图所示的列表的方法,有没有简单的方法呢?
我尝试用while循环进行迭代,但是没有运气。我没有知识提出聪明的主意,我是Python的新手。
iHaveThisList = ['a','b','c','d','e'] <-它们仍然被定义为字符串变量。
iNeedThisList = [a,a + b,a + b + c,a + b + c + d,a + b + c + d + e]
答案 0 :(得分:1)
这项工作吗? (我认为效率不是最高)

使用生成器更有效:
def cumsum(values):
return [sum(values[:i]) for i in range(1, len(values))]
