Python Concurrency with asyncio teaches you to write concurrent Python code that will boost the speed of your apps and APIs. The book demystifies asynchio's unique single-threaded concurrency model, giving you a behind-the-scenes understanding of the library and its new async/await syntax. Hard...
Depending on the task that you’re attempting, you may be able to accomplish it with the asyncio or threading modules. If everything is written in Python, then these modules are likely your best bet. The asyncio module has a high-level API to create and manage subprocesses too, so if ...

Asyncio 是并发(concurrency)的一种方式。对 Python 来说,并发还可以通过线程(threading)和多进程(multiprocessing)来实现。Asyncio 并不能带来真正的并行(parallelism)。当然,因为 GIL(全局解释器锁)的存在,Python 的多线程也不能带来真正的并行。 . 一、asyncio的异步 ...

The resulting design is radically simpler than older competitors like asyncio and Twisted, yet just as capable. Trio is the Python I/O library I always wanted; I find it makes building I/O-oriented programs easier, less error-prone, and just plain more fun. Perhaps you'll find the same....

在Python 中,你有多种并发的选择。最常见的可能是用threading模块的多线程,用subprocess和multiprocessing模块的多进程,以及最近用asyncio模块提供的async语法。在VizTracer之前,缺乏分析使用了这些技术程序的工具。 VizTracer 是一个追踪和可视化Python 程序的工具,对日志、调试和剖析很有帮助。尽管它对单线程、单任务程序很...
