在注解库 typing.py 中,定义了 Generator,AsyncGenerator,Iterator,AsyncIterator: Generator = _alias(collections.abc.Generator, 3) AsyncGenerator = _alias(collections.abc.AsyncGenerator, 2) AsyncIterator = _alias(collections.abc.AsyncIterator, 1) Iterator = _alias(collections.abc.Iterator, 1) 它们都...

This creates an asynchronous generator, which you iterate over with async for. Forget about async generators for the time being and focus on getting down the syntax for coroutine functions, which use await and/or return. Anything defined with async def may not use yield from, which will raise...

现在我们使用 async/await 语法来声明一个协程。 代码如下 import asyncio async defmain():print('hello') await asyncio.sleep(1)print('world') if __name__ =='__main__': asyncio.run(main()) asyncio.run 只能用来启动程序入口协程,反过来你在程序中如果使用asyncio.run 就会出错,直接我们提到对于其...
