在Python的列中将不同大小的列表写入csv [英] Write lists of different size to csv in columns in Python

问题描述

我需要在列中将所有长度都不同的列表写到CSV文件中.

I need to write lists that all differ in length to a CSV file in columns.

我目前有:

d=lists
writer = csv.writer(fl)
for values in zip(*d):
    writer.writerow(values)

仅部分起作用.我怀疑正在发生的事情是，它停止了压缩，直到列表的长度最短为止.

which works only partially. What I suspect is happening is that it stops zipping up until the lists with the list of the shortest length.

推荐答案

下面的代码适用于Python3.如果使用Python 2，请导入izip_longest而不是zip_longest.

Code below is for Python 3. If you use Python 2, import izip_longest instead of zip_longest.

import csv
from itertools import zip_longest

d = [[2,3,4,8],[5,6]]

with open("file.csv","w+") as f:
    writer = csv.writer(f)
    for values in zip_longest(*d):
        writer.writerow(values)

结果:

2,5
3,6
4,
8,
