I'm talking about this:

https://docs.python.org/3/library/collections.html#collections.namedtuple

It's like a tuple, but the fields also have names, so
you can access them like attributes using dot-notation.

If you derive the attribute names from the header row,
it would be extremely self-maintaining. You would be able
to reorder columns without touching the code at all.
