python - 如何在python中将数组保存到文本文件？

Question

我有一个这种类型的数组:

xyz = [['nameserver','panel'], ['nameserver','panel']]

如何以这种格式将其保存到 abc.txt 文件中:

nameserver panel
nameserver panel

我在迭代每一行时尝试使用:

np.savetxt("some_i.txt",xyz[i],delimiter=',');

它显示此错误:

TypeError: Mismatch between array dtype ('<U11') and format specifier 
('%.18e')

Answer 1

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
