python csv问题 [英] python csv question

问题描述

我只是测试出csv组件在python，我有一些麻烦。

i'm just testing out the csv component in python, and i am having some trouble with it.

我有一个相当标准的csv字符串，默认选项似乎都符合我的测试，但结果不应该分组1，2，3，4

I have a fairly standard csv string, and the default options all seems to fit with my test, but the result shouldn't group 1, 2, 3, 4 in a row and 5, 6, 7, 8 in a row?

非常感谢您提供的任何启发。

Thanks a lot for any enlightenment provided!

推荐答案

csv.reader期望可迭代。你给它1，2，3，4 \ n 5，6，7，8 \\\
;迭代产生字符。尝试给它[1，2，3，4 \\\
，5，6，7，8 \\\
] - 迭代将生成行。

csv.reader expects an iterable. You gave it "1, 2, 3, 4\n 5, 6, 7, 8\n"; iteration produces characters. Try giving it ["1, 2, 3, 4\n", "5, 6, 7, 8\n"] -- iteration will produce lines.
