你可以通过来从脚本中运行控制台命令subprocess.run(args, stdout=PIPE, stderr=PIPE, universal_newlines=True)。

Args应该是这样的列表： ['sudo', '/usr/local/sbin/openvpn', '--config', home + '/path/to/config.ovpn']

例如：

import subprocess, os

home = os.environ["HOME"]
args = [
'sudo',
'/Mike/local/sbin/openvpn',
'--config',
home + '/Mike/Downloads/office.ovpn'
    ]
r = subprocess.run(args, stdout=PIPE, stderr=PIPE, universal_newlines=True)
...
# your code which needs to be connected to openvpn
...
# kill connection
r.stdout

另一种简便的方法是使用subprocess.Popen（）：

import subprocess, psutil

# define function to kill connection
def kill(proc_pid):
    process = psutil.Process(proc_pid)
    for proc in process.children(recursive=True):
        proc.kill()
    process.kill()

# use shell command to connect openvpn
r = subprocess.Popen(shell_command, shell=True)

...
# your code
...

# kill connection
kill(r.pid)
