CSV module: incorrectly parsed file.

[Christopher Barrington-Leigh]

Here is a file "test.csv"
number,name,description,value
1,"wer","tape 2"",5
1,vvv,"hoohaa",2

I want to convert it to tab-separated without those silly quotes. Note
in the second line that a field is 'tape 2"' , ie two inches: there is
a double quote in the string.

When I use csv module to read this:


import sys
outf=open(sys.argv[1]+'.tsv','wt')
import csv
reader=csv.reader(open(sys.argv[1], "rb"))
for row in reader:
    outf.write('\t'.join([rr.strip() for rr in row]) +'\n')


it mangles it, messing up the double double-quote.
Can anyone help me? How do I use CSV to get it right?
Tjhanks!
