Question

我的列表如下，

lista=["a","b","c","\n","d","e","f","\n","g","h","i","\n"]

有人可以告诉我如何让csv模块写这个，以便每个＆＃34; \ n＆＃34;在列表中被计为换行符？为了简化，csv应该是这样的，

a,b,c

d,e,f

g,h,i

如果问题不明确，请告诉我，我会根据需要进行更改。

Answer 1

import csv
import sys

def rows(lst):
    it = iter(lst)
    while True:
        row = list(iter(it.next, '\n'))  # it.__next__ in Python 3.x
        if not row:
            break
        yield row

lista = ["a","b","c","\n","d","e","f","\n","g","h","i","\n"]
writer = csv.writer(sys.stdout)  # Replace sys.stdout with file object
writer.writerows(rows(lista))

Answer 2

您真的不需要CSV模块：

for s in ','.join(lista).split('\n'):
    print(s.strip(','), '\n')

这给出了：

a,b,c

d,e,f

g,h,i

CSV模块用于在列表中写入新行数据
