help me out have browse none document available...
you have 2 questions. pun 1 question per stackoverflow question. addresses first one.
to capture stdout or stderr output program can use subprocess.check_output().
"run command arguments , return output."
example:
import subprocess output = subprocess.check_output("dmidecode") print(output.decode("utf-8")) # convert bytes string when have output available can ask question how parse it, , want parsed data.
