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 ...
Run the command described byargs. Wait for command to complete, then return aCompletedProcessinstance. 运行被args描述的指令。等待指令完成,然后返回一个CompletedProcess示例。 strong@foreverstrong:~/Desktop/screenshot$ python3 Python 3.5.2 (default, Nov 23 2017, 16:37:01) [GCC 5.4.0 20160609] on...
A step-by-step illustrated guide on how to wait for subprocesses to finish in Python in multiple ways.

Anyway, I'd love to update my stuff to use the subprocess module, but really haven't ever found any examples - specifically of launching a subprocess (or many subprocesses) and having the master script not "wait" (e.g. sit there like a dummy) until the subproce...

python 无阻塞subprocess.call您应该使用subprocess.Popen而不是subprocess.call。比如：
1os.getcwd() 获取当前工作目录,即当前python脚本工作的目录路径2os.chdir("dirname") 改变当前脚本工作目录;相当于shell下cd3os.curdir 返回当前目录: ('.')4os.pardir 获取当前目录的父目录字符串名:('..')5os.makedirs('dirname1/dirname2') 可生成多层递归目录6os.removedirs('dirname1') 若目录为空,...
