Python:使用 subprocess.Popen 加载 python 脚本时传递 sys.argv [英] Python: pass sys.argv when loading python script with subprocess.Popen

问题描述

我有一个使用 subprocess.Popen 打开文件的脚本，因此我可以在后台运行它.我希望能够使用 ./[script] [params]

I have a script that opens a file using subprocess.Popen so I can run it in the background. I would like to be able to run this script with ./[script] [params]

#!/usr/bin/python
import subprocess
import sys
sys.path.insert(0,"./pyqt")
import gui

if __name__ == "__main__":
    subprocess.Popen(["python", "./pyqt/gui.py"])

gui.py 可以在从终端运行时使用 sys.argv 获取参数.下面是我如何在 gui.py 中访问这些参数

gui.py can take parameters when being ran from a terminal by using sys.argv. Below is how I am accessing these params in gui.py

def main(*args):
    print(args)

if __name__ == "__main__":
    main(sys.argv)

如何将 sys.argv 传递给 subprocess.Popen?

How can I pass sys.argv into subprocess.Popen?

推荐答案

只需转发/连接 subprocess.Popen() 调用中的参数:

Just forward/concatenate the arguments in the subprocess.Popen() call:

if __name__ == "__main__":
    subprocess.Popen(["python", "./pyqt/gui.py"] + sys.argv[1:])
