Confused About Python Loggin

Dear all, I am quite confused about the Python logging. I have read  
and re-read the Python documentation for the Python logging module and  
googled, but to no avail. I simply want one logger to log to a file  
and another logger to log to the console. Neither should log the  
other's messages. The code below causes fileLogger to log to BOTH a  
file and the console, how come? It seems to me that a call such as  
"consoleHandler = logging.StreamHandler()" affects other loggers,  
which I do not want. Also, if I do not do  
logging.basicConfig(level=logging.INFO) in one of the classes of my  
application, the logging does not work. Any ideas how come?

Thanks a lot for any help! :)

fileHandler = logging.FileHandler('../../logs/log.txt')
fileLogger = logging.getLogger('TESTHARNESSFILE')
fileLogger.addHandler(fileHandler)
fileLogger.setLevel(logging.INFO)
consoleHandler = logging.StreamHandler()
logger = logging.getLogger('TESTHARNESS')
logger.addHandler(consoleHandler)
logger.setLevel(logging.INFO)
