用法: inspect.isasyncgenfunction(object)如果对象是异步生成器函数,则返回 True,例如:>>> async def agen(): ... yield 1 ... >>> inspect.isasyncgenfunction(agen) True3.6 版中的新函数。在3.8 版中更改:封装的函数functools.partial现在返回True如果包装的函数是异步生成器函数。

最新版的 python 已经不采用基于 yield 的协程了。但我这里则只用yield 和 yield from 来实现协程,而不使用 await 与 async。这样能更好地展示生成器到协程的全过程,原理也都是相通的。 我们先看一个最简单的 yield 例子 代码语言:javascript 复制

if (PyCoro_CheckExact(o) || gen_is_coroutine(o)) return o getter = ot->tp_as_async->am_await PyObject *res = (*getter)(o) 可以知晓,如果对象是协程的话会直接返回,不是协程的话看有无ot->tp_as_async->am_await接口支持。如果再追究的话,对于一般的生成器PyGen_Type,是没有这个接口的,...
