unable to provide password to a process with subprocess [python]

Question

I\'m using subprocess to run a script from within python. I tried this

option 1

password = getpass.getpass()
from subprocess import Popen, PIPE, che         


        

Answer 1

You should be passing the password as a value to the communicate() function instead of stdin.write(), like so:

from getpass import getpass
from subprocess import Popen, PIPE

password = getpass("Please enter your password: ")
proc = Popen("command option1 option2".split(), stdin=PIPE, stdout=PIPE)
# Popen only accepts byte-arrays so you must encode the string
proc.communicate(password.encode())
