Python script not working on windows 7 but works fine on linux

[io]

The following scripts are working fine on linux but, using the same 
version, can't work on windows because i receive the following message:

Script:


import json
import urllib
import csv

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

f = open("/home/io/btc_trading/markets.csv","wb")
c = csv.writer(f)

#apre un file di testo e legge il contenuto del file inserendolo in una 
stringa
esclusioni_file = open('/home/io/btc_trading/exclusions.txt','r')
esclusioni = []

for line in esclusioni_file:
     esclusioni.append(line.strip())
#print(esclusioni)


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

for d in data :
    if d["currency"] <> "SLL":  #esclude la valuta di secondlife SLL
        if d["bid"] is not None and d["ask"] is not None:
            if d["symbol"] not in esclusioni:
                #print d["symbol"]
                c.writerow([str(d["currency"]),str(d["symbol"]),str(d
["bid"]),str(d["ask"]),str(d["currency_volume"])])
    #esclusioni.close()

Windows error :
