Solve the following python programming problem given the following code:
@ classmethod 
def define_tables(cls, metadata) : 
    import json 
    class JSONEncodedDict (TypeDecorator) : 
        impl = VARCHAR (50) 
        def process_bind_param(self, value, dialect) : 
            if (value is not None) : 
                value = json.dumps (value) 
return value 
def process_result_value(self, value, dialect) : 
            if (value is not None) : 
                value = json.loads (value) 
return value 
MutableDict = cls._type_fixture () 
    MutableDict.associate_with (JSONEncodedDict) 
    Table ('foo', MutableDict, Column ('id', Integer, primary_key = True, test_needs_autoincrement = True), Column ('data', JSONEncodedDict), Column ('unrelated_data', String (50))) 

    
    

    Fix the buggy line: Table ('foo', MutableDict, Column ('id', Integer, primary_key = True, test_needs_autoincrement = True), Column ('data', JSONEncodedDict), Column ('unrelated_data', String (50)))

#Here is Python code to fix the buggy line: Table ('foo', MutableDict, Column ('id', Integer, primary_key = True, test_needs_autoincrement = True), Column ('data', JSONEncodedDict), Column ('unrelated_data', String (50)))
.

Table ('foo', metadata, Column ('id', Integer, primary_key = True, test_needs_autoincrement = True), Column ('data', JSONEncodedDict), Column ('unrelated_data', String (50)))
