Can you be more specific? What are you trying to do with it?

What extra facilities do you think there should be?

Perhaps you'd better explain what you mean by "working by". Here's my
take on it:

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. *Additional*
functionality e.g. to suck the file into a list of lists that could be
accessed easily by column index is possible, but it is well within the
competence of average Python programmers to write that themselves:

    data = [row for row in csv.reader(......)]
    ...
    whatever = data[row_index][col_index]

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.

AFAIK, no.

Is your googler broken?

In what language?
