The Python subprocess module is used to run shell commands and manage external processes. You run a shell command using subprocess by calling subprocess.run() with the command as a list of arguments. subprocess.call(), subprocess.run(), and subprocess.Popen() differ in how they execute ...
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.

subprocess – 子进程(独立) 作用:创建一个新的独立进程来执行代码。 特点: 每个子进程拥有自己的内存空间,和主进程是完全隔离的 适合CPU 密集型任务,可以利用多核 CPU 并行处理。 更适合执行系统命令或外部脚本(比如运行 shell 命令)。 缺点: 不适合直接在子进程之间或子进程与主进程之间频繁通信(需要额外的通信...
Themultiprocessingpackage offers both local and remote concurrency, effectively side-stepping theGlobal Interpreter Lockby using subprocesses instead of threads. Due to this, themultiprocessingmodule allows the programmer to fully leverage multiple processors on a given machine. It runs on both Unix and...
