等待一个过程以Python脚本完成

Question

I'm writing a Python script to run several executables one by one on Windows. I need to wait a program to finish before starting the next.

So the script will be like this.

1: launch a.exe
2: wait till a.exe finishes running
3: launch b.exe
4: wait till b.exe finishes 

Anyone have an idea how to make the script waiting for a process to finish in Python?

Thanks

If you wish to wait for your launched process, you can simply use subprocess.call() . This method executes the command in args and waits for it to complete. For reference, see this

import subprocess
subprocess.call(('someprog.exe', str(i)))
