The key goal is to provide a base library for the GitHub API which performs no I/O of its own (a sans-I/O library). This allows users to choose whatever HTTP library they prefer while parceling out GitHub-specific details to this library. This base library is then built upon to provid...

类似的，要编写异步代码，就把所有异步代码放到一个异步函数里（async def ...），然后用asyncio.run(...

coroutines are functions whoseexecutionyou can pause。(来自How the heck does async/await work in Python 3.5?) 这不就是生成器吗? python2.2 - 生成器起源 Python生成器的概念最早起源于 python2.2(2001年)时剔除的pep255,受Icon 编程语言启发。
在Python 3 asyncio中实现同步等待回调的方法是使用async/await关键字结合asyncio库的协程特性。下面是一个实现同步等待回调的示例代码: 代码语言:python 代码运行次数:0 复制Cloud Studio 代码运行 import asyncio async def callback(): await asyncio.sleep(1) # 模拟异步操作 return 'Callback result' async...
