Solve the following python programming problem given the following code:
def __init__(self, q = None, formatter = colorizer, retain_recent = 0) : 
    if q : 
        self.q = q 
else : 
        self.q = queue.Queue (300) 
self.formatter = formatter 
    self.quietmode = False 
    self.background_thread = threading.Thread (target = self.console_thread, args = ()) 
    self.background_thread.setDaemon (True) 
    self.background_thread.setName ('Console Output') 
    self.background_thread.start () 
    def limit_deque() : 
        return deque ([], retain_recent) 
self.retain_recent = retain_recent 
    self.recent_history = defaultdict (formatter) 

    
    

    Fix the buggy line: self.recent_history = defaultdict (formatter)

#Here is Python code to fix the buggy line: self.
