I'm trying to add a wifi network on the raspberry pi via bash inside a python script.

I want to run a subprocess in administrator mode inside a python application, does anyone have any suggestions to help me?

I need to edit the file:

/etc/wpa_supplicant/wpa_supplicant.conf

The entire command I need to execute is:

sudo echo "network={ssid="rede" psk="pass" key+mgmt=WPA-PSK}" >> /etc/wpa_supplicant/wpa_supplicant.conf

I was able to find an answer, I don't know if it is the right one for the application, but it worked.

import subprocess

cmd_permission="sudo chmod 777 /etc/wpa_supplicant/wpa_supplicant.conf"
subprocess.run(cmd_permission, shell=True)
cmd="sudo echo "network={ssid="rede" psk="pass" key+mgmt=WPA-PSK}" >> /etc/wpa_supplicant/wpa_supplicant.conf"
subprocess.run(cmd, shell=True)

Security Considerations Unlike some other popen functions, this implementation will never implicitly call a system shell. This means that all characters, including shell metacharacters, can safely be passed to child processes. If the shell is invoked explicitly, via , it is the application’s responsibility to ensure that all whitespace and metacharacters are quoted appropriately to avoid shell injection vulnerabilities.shell=True

When using , the shlex.quote() function can be used to properly escape whitespace and shell metacharacters in strings that are going to be used to construct shell commands.shell=True
