[Baypiggies] Want to redirect output to a csv file

Funny thing... I was reading and writing csv files just now.
I preprocess input files to make sure all the lines have same number  
of fields as the header

checkcsv.py < input.csv > good.csv 2>bad.csv

The good lines go to stdout, the bad lines go to stderror.

#!/usr/bin/env python
import csv
import sys

reader = csv.reader(sys.stdin)
error = csv.writer(sys.stderr)
output = csv.writer(sys.stdout)

header = reader.next()
fields = len(header)


for line in reader:
     if len(line) == fields:
