low-level csv

[Antoon Pardon]

This is python 2.6->2.7 and 3.5->3.7

I need to convert a string that is a csv line to a list and vice versa.
I thought to find functions doing this in the csv module but that doesn't
seem to be the case.

I can of course write special classes that would allow for this using
a csv.reader and csv.writer but that would be some convoluted code.

Anyone some suggestions?
