Solve the following python programming problem given the following code:
def bind_processor(self, dialect) : 
    if util.py2k : 
        encoding = self.encoding 
        def process(value) : 
            if isinstance (value, dict) : 
                return _serialize_hstore (value).encode (encoding) 
else : 
                return value 
else : 
        def process(value) : 
            if isinstance (value, dict) : 
                return _serialize_hstore (value) 
else : 
                return value 
return process 

    
    

    Fix the buggy line: encoding = self.encoding

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

encoding = dialect.encoding
