Why 'os.system' exits with return code 1?

I want to execute some adb commands from python script. But when i executed the following line

os.system('adb devices')

The cmd returns with 1 instead of 0. I also tried executing

os.popen('adb devices').read()

I am getting empty string. Please help me to solve this. Note: I tried the same commands from command window and it was working fine. I also added the path of adb.exe to windows PATH environment variable.

According to Windows docs, you've got 1, because there was an error on your command.

Maybe use subprocess could be a better approach.

import subprocess

subprocess.check_output(
    "adb devices", 
    stderr=subprocess.STDOUT,
    shell=True)
