Yes, but maybe I was in the wrong. I'm not so bold to submit patches to an official Python module without asking. *I* feel troubles, but maybe it's just me being dense. > > > I > > find it especially cumbersome to use, > > Can you be more specific?

Ability to work by columns together with rows and maybe some random access facilities would be nice. A more user-friendly interface too. > A CSV file is organised such that each line of the file represents a > row, and the nth field in the line relates to the nth column, so it's > natural for any CSV reader/writer to work by rows. Yes, but it's natural for a spreadsheet-like thing to have organized columns of data, often. Often I want those columns to be read into lists, or to write lists into columns. The actual csv doesn't allow this naturally. Especially writing is a bit painful. I just wanted to know if there was something allowing this with a simple command, that I missed, or if just there wasn't. > Accessing the data by columns *instead* of by rows would definitely > not be appreciated by people who are using the csv module to read > millions of lines of data.

I googled but apart from some hint here and there of someone thinking about writing a pure Python csv module, I found nothing.
