Thanks Stanley!
That's another nice code to use!

I was trying to sort out some condition but can't get this working :

import json
import urllib
import csv

url = "http://bitcoincharts.com/t/markets.json"
response = urllib.urlopen(url);
data = json.loads(response.read())

f = open("bitcoin.csv","wb")
c = csv.writer(f)

# write headers
c.writerow(["Currency","Symbol","Bid", "Ask", "Volume"])

#if str(d["bid"])and str(d["ask"])[0] not in ( 'none' ):
    
for d in data where str(d["bid"])and str(d["ask"])[0] not in ( 'none' ):
    c.writerow([str(d["currency"]),str(d["symbol"]),str(d["bid"]),str(d
["ask"]),str(d["currency_volume"])])
