It looks like the author of the nasdaq_stock module was interested in a 
quick and dirty tool for personal needs rather than a clean library for 
general use.

The text quoted above is printed implicitly by the stock() function. To 
suppress it you have to modify that function or to redirect sys.stdout.

Another problem with the code is that it may swallow arbitrary exceptions. 
Therefore my error message below has to be vague.

If all goes well the stock function returns the above dict.

import sys
from nasdaq_stock import nasdaq_stock
 
stock_info = nasdaq_stock.stock('AAPL')

print
if stock_info:
    price = stock_info["price"]
    ticker = stock_info["ticker"]
    print "Ticker:", ticker, "Price:", price
else:
    print >> sys.stderr, "Something went wrong"
