Asynchronous code object marked with the CO_COROUTINE flag may then be returned. compile()内置程序已经改进,可以接受ast.pycf_allow_top_level_await标志。传递新标志后,compile()将允许顶级await、async for和async with构造,这些构造通常被视为无效语法。然后可以返回标记有co_coroutine标志的异步代码对象。 4...

pickle,用于python特有的类型 和 python的数据类型间进行转换 json:json是一种所有的语言都可以识别的数据结构.如果将一个字典或者序列化成了一个json存在文件里,那么java代码或者js代码也可以拿来用。 **pickle: **用pickle进行序列化,其他语言是不能识别的, 如果python对这个数据进行反序列化的话,那么就可以使用pi...
If factory is a callable, it should have a signature matching '(loop, coro, **kwargs)', where 'loop' will be a reference to the active event loop, 'coro' will be a coroutine object, and **kwargs will be arbitrary keyword arguments that should be passed on to Task. The callable ...
The resulting object is callable, so you can just call it to invoke function with the filled-in arguments. 这里有一个很小但很现实的例子: import functools def log (message, subsystem): "Write the contents of 'message' to the specified subsystem." print '%s: %s' % (subsystem, message) ...
New run_coroutine_threadsafe() function to submit coroutines to event loops from other threads. (Contributed by Vincent Michel.) New Transport.is_closing() method to check if the transport is closing or closed. (Contributed by Yury Selivanov.) The loop.create_server() method can now accept ...
