Get shell script “read” value from python script

Question

Shell script: Hello.sh

#!/bin/bash
echo "Enter your name: "
read name
echo "Hello $name"

I want to invoke Hello.sh from within python and fill variable "name" non-interactively. How can it be done?

do you want to give the value from variable "name" to a python script or get the variable name from a python script? — Paul Seeb, Mar 21 at 13:17
To clarify: he likely wants to invoke Hello.sh from within python and "fill" name noninteractively. If so, I believe that the answer John's looking for is to use subprocess and write to the stdin handle. — Brian Cain, Mar 21 at 13:27

Not sure how to read your question.

EDIT: Comment was added by the OP: invoke Hello.sh from within python and "fill" name noninteractively

Which changes things, so here is a different answer for the new question:

import subprocess
cmd = '/home/user1/Hello.sh'
proc = subprocess.Popen(cmd, stdin=subprocess.PIPE)
proc.communicate("Fred Bloggs")

I have used the full path to the script, it is safer.
