Question

I have a nested list comprising ~30,000 sub-lists, each with three entries, e.g.,

nested_list = [['x', 'y', 'z'], ['a', 'b', 'c']].

I wish to create a function in order to output this data construct into a tab delimited format, e.g.,

x    y    z
a    b    c

Any help greatly appreciated!

Thanks in advance,
Seafoid.

with open('fname', 'w') as file:
    file.writelines('\t'.join(i) + '\n' for i in nested_list)
