【问题描述】：

我有一些这样的列表：

[['CD', 'CC', 'CD'], 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]
[['DT', 'CC', 'CD'], 0, 0, 1, 0, 1, 0, 1, 1, 1, 1, 1, 1] 
[['EX', 'CC', 'CD'], 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] 
[['JJ', 'CC', 'CD'], 0, 0, 1, 0, 1, 0, 1, 1, 0, 1, 1, 1]

我想将这些列表写入 csv 文件列。到目前为止我做了什么：

for i in range(1,840):
    # function which compute the result value
    result=Count_SP(i,leng_second,first_position+1,second_position)
    final.append(result)


print final             # final contains lists      
File_Write(final)       # File_Write() writes the final into a csv file

需要输出：

['CD', 'CC', 'CD'],['DT', 'CC', 'CD'],['EX', 'CC', 'CD'],['JJ', 'CC', 'CD']
1,0,0,0
1,0,0,0
1,1,0,1
1,0,0,0
1,1,0,1
1,0,0,0
1,1,0,1
1,1,0,1
1,1,0,0
1,1,0,1
1,1,0,1
1,1,0,1

【解决方案1】：

如果你把你的列表放在一个容器里，那其实很简单：

import csv

container = [[['CD', 'CC', 'CD'], 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
             [['DT', 'CC', 'CD'], 0, 0, 1, 0, 1, 0, 1, 1, 1, 1, 1, 1],
             [['EX', 'CC', 'CD'], 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
             [['JJ', 'CC', 'CD'], 0, 0, 1, 0, 1, 0, 1, 1, 0, 1, 1, 1]]

with open('out.csv', 'w') as csvfile:
    csvw = csv.writer(csvfile, delimiter=',')
    for column in zip(*[s for s in container]):
        csvw.writerow(column)

这将创建文件out.csv，其中将包含输入列表列：

"['CD', 'CC', 'CD']","['DT', 'CC', 'CD']","['EX', 'CC', 'CD']","['JJ', 'CC', 'CD']"
1,0,0,0
1,0,0,0
1,1,0,1
1,0,0,0
1,1,0,1
1,0,0,0
1,1,0,1
1,1,0,1
1,1,0,0
1,1,0,1
1,1,0,1
1,1,0,1
