这是一个可能的解决方案：

data = [['nameservers','panel'], ['nameservers','panel']]

with open("output.txt", "w") as txt_file:
    for line in data:
        txt_file.write(" ".join(line) + "\n") # works with any number of elements in a line

字符串

可能最简单的方法是使用json模块，并在一个步骤中将数组转换为列表：

import json

with open('output.txt', 'w') as filehandle:
    json.dump(array.toList(), filehandle)

字符串
使用json格式允许许多不同系统之间的互操作性。

使用csv.writer：

import csv

data = [['nameservers','panel'], ['nameservers','panel']]

with open('tmp_file.txt', 'w') as f:
    csv.writer(f, delimiter=' ').writerows(data)

字符串
tmp_file.txt现在喜欢这个

nameservers panel
nameservers panel

型

众多可能性之一：

stuff = [['nameservers','panel'], ['nameservers','panel']]
with open("/tmp/out.txt", "w") as o:
    for line in stuff:
        print("{} {}".format(line[0], line[1]), file=o)

字符串

您可以直接将其写入文件。

with open('outfile.txt', 'w') as f:
    f.write('\n'.join([' '.join(l2) for l2 in l1]))

字符串
其中l1是您给出的列表。

另一种解决办法可能是：

# import packages
from numpy import asarray
from numpy import savetxt

# Lets say you have the data in `y`
data = asarray(y)

# Save the file
savetxt('data.csv', data, delimiter=',')
