Callable type;Callable[[int],str]is afunctionof(int)->str. 第一个类型(int)代表参数类型 第二个类型(str)代表返回值类型 栗子 代码语言:javascript 代码运行次数:0 运行 AI代码解释 defprint_name(name:str):print(name)# Callable 作为函数参数使用,其实只是做一个类型检查的作用,检查传入的参数值 get_...
form typingimportNewType UserId=NewType("UserId",int)some_id=UserId(524313) 静态类型检查器将将新类型视为原始类型的子类。这对于帮助捕获逻辑错误非常有用 代码语言:python 代码运行次数:0 运行 AI代码解释 defget_user_name(user_id:UserId)->str:pass# typechecksuser_a=get_user_name(UserId(42351)...

生成器函数:主体中有yield的函数,调用生成器函数返回一个生成器对象。 原生协程函数:使用async def 定义的函数或者方法,调用原生协程函数返回一个协程对象。 异步生成器函数:使用async def 定义,而且主体中有yield关键字,调用异步生成器函数返回一个异步生成器,供async for 使用。只要...
