I want to call a child process to run a shell script and wait for that script

do I make it wait?
Any help appreciated.
import subprocess
command = "/home/john/myscript"
process = subprocess.Popen(command,
stdin=subprocess.PIPE,stdout=subprocess.PIPE, stderr=subprocess.PIPE,
close_fds=True, shell=True)
out, err = process.communicate()
returncode = process.returncode
Yes, communicate() will block until the child process is complete.

Note the phrase: "Wait for process to terminate." That's referring to
the shell in your case.
