Solve the following python programming problem given the following code:
def make_timing_logger(logger, precision = 3, level = logging.DEBUG) : 
    ' Return a timing logger.

    Usage::

        >>> logger = logging.getLogger(\'foobar\')
        >>> log_time = make_timing_logger(
        ...     logger, level=logging.INFO, precision=2)
        >>>
        >>> with log_time("hello %s", "world"):
        ...     time.sleep(1)
        INFO:foobar:hello world in 1.00s
    ' 
    @ contextmanager 
    def log_time(msg, * args) : 
        ' Log `msg` and `*args` with (naive wallclock) timing information
        when the context block exits.
        ' 
        start_time = time.time () 
        try : 
            (yield) 
finally : 
            message = '{} in %0.{}fs'.format (msg, precision) 
            duration = (time.time () - start_time) 
            args = (args + (duration,)) 
            logger.log (level, message, * args) 
return level 

    
    

    Fix the buggy line: return level
