password = input("Neopets password: ")

acc = NeoAccount(username, password)
if acc.login():

    html = acc.get("http://www.neopets.com/inventory.phtml")

    if match:
        itemCount = match.group(1)
    else:
        itemCount = "0"
    print(username + " has " + itemCount + " items!")
else:
    print("Failed to login to " + username)
