[FIXED] How save a array to text file in python?

Issue

I have a array of this type:

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

How can I save this to an abc.txt file in this format:

nameserver panel
nameserver panel

I tried this using, on iterating over each row:

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

It's showing this error:

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

Solution

This is a possible solution:

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
