This is a possible solution:
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

One of many possibilities:
许多可能性之一：
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)

Probably the simplest method is to use the json module, and convert the array to list in one step:
可能最简单的方法是使用 json 模块，并一步将数组转换为列表：
import json
with open('output.txt', 'w') as filehandle:
json.dump(array.toList(), filehandle)
Using the json format allows interoperability between many different systems.
使用 json 格式允许许多不同系统之间的互操作性。

Use csv.writer
用 csv.writer
data = [['nameservers','panel'], ['nameservers','panel']]
with open('tmp_file.txt', 'w') as f:
csv.writer(f, delimiter=' ').writerows(data)
tmp_file.txtwould now like this
tmp_file.txt现在想要这个
nameservers panel
nameservers panel

You can just write it out to a file directly.
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]))
where l1is the list you gave.
l1你给的清单在哪里。
