使用create_subprocess_exec()函数在zen()协create_subprocess_exec() Python进程,并将标准输出绑定到管道。 然后,使用await逐行迭代标准输出,以使其他进程或协程有机会在输出尚未准备好时执行。 请注意,在Windows上,您必须将事件循环设置为ProactorEventLoop因为标准的SelectorEventLoop不支持管道。 import asyncio.subproc...
Most of your interaction with the Python subprocess module will be via the run() function. This blocking function will start a process and wait until the new process exits before moving on. The documentation recommends using run() for all cases that it can handle. For edge cases where you ...

The multiprocessing package offers both local and remote concurrency,effectively side-stepping the Global Interpreter Lock by using subprocesses instead of threads. Due to this, the multiprocessing module allows the programmer to fully leverage multiple processors on a given machine. It runs on both ...
