对python列表里的字典元素去重方法详解
简介如下所示：def list_dict_duplicate_removal():data_list = [{"a": "123", "b": "321"}, {"a": "123", "b": "321"}, {"b": "321", "a": "123"}]run_function = lambda
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'}]
