async def download(url: str, download_path: str, filename: str, suffix: str) -> str: return 'foo' 现在download有签名 def (url: builtins.str, download_path: builtins.str, filename: builtins.str, suffix: builtins.str) -> typing.Awaitable[Union[builtins.str, None]] ...
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...
