Solve the following python programming problem given the following code:
def __call__(self, fn) : 
    'Function wrapper.' 
    @ wraps (fn) 
    def wrapped_f(* args, **kwargs) : 
        c = 0 
        while (c <= self.retry_count) : 
            try : 
                return fn (* args, ** kwargs) 
except : 
                logging.critical ('retrying because of this exception - %s', c) 
                logging.exception ('exception to retry ') 
                if (c == self.retry_count) : 
                    raise 
c += 1 
return self
