Tab Delimited Strings?

[johnywhy]

what is your actual use case? Do you need to print out elements of lists/tuples of arbitrary length or do you always have only 2 elements?

Always 2 elements followed by newline.

Depending on what you are writing, you can just use format string like print(f"{idx[0]}\t{idx[1]}\n")

I'm just trying to assemble the string here, not print it. How to do that with f?
My terms are just str(idx) and choice, with a trailing newline.

you can define your own __str__ method in a data class.

I'd like to learn how, but sounds even more complicated.
