Would you like us to guess what happened? I love guessing games!
My guess is that it output "su: incorrect password", which means you have
the wrong password. Is that it?
If not, my guess is that it output "fdisk: command not found", in which
case your system is broken and the fdisk binary is missing or not on the
PATH. Am I close?
Last guess: you got a Python traceback with an error:
NameError: name 'subprocess' is not defined
You need to import the subprocess first.
If none of my guesses are correct, could we have some hints? Perhaps show
us the actual code you are using, and the actual results, copied and
pasted exactly.
Thank you.
