Question

Starting with this from Corey Goldberg:

#!/usr/bin/env python

import json
import pprint
import urllib2


def get_stock_quote(ticker_symbol):   
    url = 'http://finance.google.com/finance/info?q=%s' % ticker_symbol
    lines = urllib2.urlopen(url).read().splitlines()
    return json.loads(''.join([x for x in lines if x not in ('// [', ']')]))


if __name__ == '__main__':
    quote = get_stock_quote('IBM')
    print 'ticker: %s' % quote['t']
    print 'current price: %s' % quote['l_cur']
    print 'last trade: %s' % quote['lt']
    print 'full quote:'
    pprint.pprint(quote)

Using this:

import urllib2, json

def get_stock_quote(ticker_symbol):   
    url = 'http://finance.google.com/finance/info?q=%s' % ticker_symbol
    lines = urllib2.urlopen(url).read().splitlines()
    #print lines
    return json.loads(''.join([x for x in lines if x not in ('// [', ']')]))



if __name__ == '__main__':
    symbols = ('Goog',) 
    symbols2 = ('Goog','MSFT')
    quote = get_stock_quote(symbols)
    print 'ticker: %s' % quote['t'],  'current price: %s' % quote['l_cur'], 'last trade: %s' % quote['ltt']
    print quote['t'],  quote['l'], quote['ltt']

Usings symbols works, symbols2 does not work. The error message is

TypeError: not all arguments converted during string formatting

How do I convert all arguments to string in string formatting. In browser, the code that works is: Goog,MSFT.

EDIT: the output I am looking for is a list with goog, msft info.

Answer 1

In this case you can make:

import urllib2, json

def get_stock_quote(ticker_symbol):
    if isinstance(ticker_symbol, (list, tuple)):
        ticker_symbol = ','.join(ticker_symbol)
    url = 'http://finance.google.com/finance/info?q=%s' % ticker_symbol
    lines = urllib2.urlopen(url).read().splitlines()
    #print lines
    return json.loads('[%s]' % ''.join([x for x in lines if x not in ('// [', ']')]))

if __name__ == '__main__':
    symbols = ('Goog',) 
    symbols2 = ('Goog','MSFT')
    quotes = get_stock_quote(symbols2)
    for quote in quotes:
        print 'ticker: %s' % quote['t'],  'current price: %s' % quote['l_cur'], 'last trade: %s' % quote['ltt']
        print quote['t'],  quote['l'], quote['ltt']
