从图形Python程序使用sudo运行命令

Question

I want to create a graphical python application that can execute some external programs on Linux without showing the terminal.

First, I tried to use subprocess.run() to see if it actually works, but Python 3.7.3 shows no results to the code I wrote.

import subprocess
subprocess.run(['sudo', 'apt', 'update'])

I changed it to see any results:

import subprocess
a = subprocess.run(['sudo', 'apt', 'update'])
print(a)

but it shows this result instantly:

CompletedProcess(args=['sudo', 'apt', 'update'], returncode=1)

This script will take at least 5 seconds to be finished, and it requires sudo privileges to be able to run it in the first place, so I don't think that Python shell executed this script.

Answer 1

Using pkexec instead of sudo fixed my issue. Thanks for everyone tried to help me especially @Charles Duffy.

Now it looks like this:

import subprocess
result = subprocess.run(['pkexec', 'apt', 'update'], stdout=subprocess.PIPE)
print(result.stdout)
