英文:
Starting a shell script in a new Terminal using python and get exit code
问题
I'm currently trying to run a shell script via python in a new terminal. So far it is working right now, my issue now is that I also need the exit code of that shell script. Depending on successful execution or not the script returns different exit codes and I need to get them so I can continue working with them in python. My code looks like that right now:
process = subprocess.Popen(['gnome-terminal', '-x', './myscript.sh'])
text = process.communicate()[0]
exit_code = process.returncode
print(text, exit_code)
I probably also need a wait function, because the script needs few seconds to finish execution. Does anyone know how I can do all that?

如@tjm3772在评论中提到的，subprocess.run 可能是你想要的。例如：
import subprocess
process = subprocess.run(['bash', './bash_script.sh'], capture_output=True, timeout=120)
text = process.stdout
exit_code = process.returncode
print(text, exit_code)
capture_output 和 timeout 都是可选的。timeout 的单位是秒。如你从文档中所见，如果需要的话，还有许多其他选项。
run 返回一个表示已完成进程的 CompletedProcess 对象。因此，在你的Python代码中，无需担心你的shell脚本可能需要多长时间等等。（除非你可能希望像上面提到的那样设置一个timeout，以应对脚本挂起/运行时间过长的可能情况。）

As @tjm3772 mentioned in the comments, subprocess.run is probably what you want. e.g.
import subprocess
process = subprocess.run(['bash', './bash_script.sh'], capture_output=True, timeout=120)
text = process.stdout
exit_code = process.returncode
print(text, exit_code)
Both capture_output and timeout are optional. timeout is in seconds. As you'll see from the docs, there are many other options if required.
run returns a CompletedProcess object representing a process that has finished. So no need to worry about (in your Python code) how long your shell script may take etcetera. (Other than perhaps wanting a timeout as mentioned above to cover the possible scenario of your script hanging/taking too long.)
