对python列表里的字典元素去重方法详解

如下所示：

def list_dict_duplicate_removal():
 data_list = [{"a": "123", "b": "321"}, {"a": "123", "b": "321"}, {"b": "321", "a": "123"}]
 run_function = lambda x, y: x if y in x else x + [y]
 return reduce(run_function, [[], ] + data_list)

if __name__ == '__main__':
 print list_dict_duplicate_removal()

输出结果：

[{'a': '123', 'b': '321'}]
