下面只用3行代码就可以完成这个单线程服务器。 importzen_utilsif__name__=='__main__':address=zen_utils.parse_command_line('simple single-threaded server')listener=zen_utils.create_srv_socket(address)zen_utils.accept_connections_forever(listener) 多余的事情不再详细说明了,直接说单线程服务器的缺点。
if__name__=='__main__': address=zen_utils.parse_command_line('multi-threaded server') listener=zen_utils.create_srv_socket(address) start_threads(listener) 这是多线程程序的一个可能设计。主线程启动n个服务器线程。然后退出。主线程认为这n个工作线程将永远运行。因此运行这些线程的进程也会保持运行...
这就是单线程编程(single-threaded programming)。 然而,使用多个线程就像将第二跟手指放到屏幕上。每个手指还是像之前那样移动,但是它们现在是同时在移动。 但是事实上,它们并不是同时的。你的手指在交替着移动。拥有多核心(multicore)的处理器可以真正意义上的同时执行两条指令,但是Python程序有一个叫做GIL (全局解释...
asyncio异步 : asyncio— Asynchronous I/O, event loop, coroutines and tasks This module provides infrastructure for writing single-threaded concurrent code using coroutines, multiplexing I/O access over sockets and other resources, running network clients and servers, and other related primitives,也是用...
*utilize C-based implementations to enable some of the multi-core processing desired—the infamous Global Interpreter Lock (GIL) literally “locks” the CPython interpreter into functioning on only a single thread at a time regardless of the context, whether in a single or multi-threa...
view threads in a Python program using thethreadingmodule. By enumerating through all active threads, we were able to get information about each thread, such as its name, ID, and status. This can be useful for debugging and monitoring the execution of threads in a multi-threaded Python ...
Anything involving GUI programming or manipulating GUI/webpage components Multi-threaded / concurrent / asynchronous code (only supports single-threaded) Other general unsupported features: Command-line arguments (e.g.,argv[]) not supported; use hard-coded strings instead ...

If you're working with a multi-threaded app that uses native thread APIs (such as the Win32CreateThreadfunction rather than the Python threading APIs), it's presently necessary to include the following source code at the top of whichever file you want to debug: ...
