Python - 将多个列表写入文件(Python - Write multiple lists to file)

 我正在编写股票代码程序，它会将结果显示在屏幕上并将其写入文件。 我将结果显示在屏幕上没有问题，但文件中的结果并不符合我的预期。 
 
 将结果显示在屏幕上的代码： 
 
tickerList = ticker.split() 
quotes = get_stock_quote(tickerList)
for quote in quotes:
    print 'ticker: %s' % quote['t'], 'current price: %s' %    quote['l_cur'], 'last trade: %s' % quote['lt'] 
 
 结果（如我所料）： 
 
ticker: AAPL current price: 111.31 last trade: Oct 6, 4:00PM EDT
ticker: GOOG current price: 645.44 last trade: Oct 6, 4:00PM EDT
ticker: IBM current price: 148.80 last trade: Oct 6, 6:20PM EDT
 
 要写入文件的代码： 
 
for quote in quotes:
    out_quotes = ['ticker: %s ' % quote['t'], 'current price: %s ' % quote['l_cur'], 'last trade: %s ' % quote['lt']]

outfile = open('result.txt', 'w')
for quote in out_quotes:
    outfile.writelines(chain(*out_quotes))
    outfile.write('\n')
 
 结果： 
 
ticker: IBM current price: 148.80 last trade: Oct 6, 6:20PM EDT 
ticker: IBM current price: 148.80 last trade: Oct 6, 6:20PM EDT 
ticker: IBM current price: 148.80 last trade: Oct 6, 6:20PM EDT 
 
 我期待与显示在屏幕上的结果相同的结果。 任何人都可以帮助指出我的错误？ 提前致谢。 

I'm writing stock ticker program that will display the result onto the screen and also write it to file. I had no problem with display the result onto the screen, but the result in the file was not what I expected. 
 
Code to display the result to the screen:
 
tickerList = ticker.split() 
quotes = get_stock_quote(tickerList)
for quote in quotes:
    print 'ticker: %s' % quote['t'], 'current price: %s' %    quote['l_cur'], 'last trade: %s' % quote['lt'] 
 
Result (as I expected):
 
ticker: AAPL current price: 111.31 last trade: Oct 6, 4:00PM EDT
ticker: GOOG current price: 645.44 last trade: Oct 6, 4:00PM EDT
ticker: IBM current price: 148.80 last trade: Oct 6, 6:20PM EDT
 
Code to write to file:
 
for quote in quotes:
    out_quotes = ['ticker: %s ' % quote['t'], 'current price: %s ' % quote['l_cur'], 'last trade: %s ' % quote['lt']]

outfile = open('result.txt', 'w')
for quote in out_quotes:
    outfile.writelines(chain(*out_quotes))
    outfile.write('\n')
 
Result : 
 
ticker: IBM current price: 148.80 last trade: Oct 6, 6:20PM EDT 
ticker: IBM current price: 148.80 last trade: Oct 6, 6:20PM EDT 
ticker: IBM current price: 148.80 last trade: Oct 6, 6:20PM EDT 
 
I was expecting the same result as the one displayed onto the screen. Anyone can help to point out my mistake? Thanks in advance.
