python中from typing import NamedTuple Python中的NamedTuple Python是一种动态类型的编程语言,这意味着在编写代码时,我们通常不需要显式地指定变量的类型。然而,Python 3.5引入了typing模块,使我们能够对变量和函数进行类型注释,以提高代码的可读性和可维护性。其中,NamedTuple是typing模块中的一个重要类,它提供了一种创...
在Python 3.11及更高版本中,namedtuple已经从typing模块中移除,并被整合到了collections.namedtuple中。为了在旧版本的Python代码中使用具有泛型功能的namedtuple,可以从typing_extensions模块中导入它。这样做可以确保代码的兼容性,并允许在类型注解中使用泛型。 python from typing_extensions import namedtuple 了解Python 3....

Tuple、NamedTuple Dict、Mapping、MutableMapping Set、AbstractSet Sequence Callable Union Optional 案例实战 参考链接: 写在篇前 typing 是python3.5中开始新增的专用于类型注解(type hints)的模块,为python程序提供静态类型检查,如下面的greeting函数规定了参数name的类型是str,返回值的类型也是str。
