使用[递归pydantic模型](# 3.1.2 递归模型)、typing 的标准类型 (如 List、Tuple 和Dict 等) 和验证器,可以很清晰且容易地定义、验证和解析复杂数据模式。 可拓展 pydantic允许定义[自定义数据类型](# 3.2.7 自定义数据类型),或者您可以使用被 validator 装饰器装饰的模型上的方法来扩展验证。 dataclasses 集成...

This is a faster and more idiomatic way of using itertools.chain. Instead of computing all the items in the iterable and storing them in memory, they are computed one-by-one and never stored as a huge list. This can save on both runtime and memory space, #1642 by @cool-RR Add ...
