Capture value from shell script and use it in Python without using subprocess

Question

I have a python script which requires a value from a shell script.

Following is the shell script (a.sh):

#!/bin/bash
return_value(){
  value=$(///some unix command)
  echo "$value"
}

return_value

Following is the python script:

Import subprocess
answer = Subprocess.call([‘./a.sh’])
print("the answer is %s % answer")

But its not working.The error is:

ImportError : No module named subprocess

I guess my verison (Python 2.3.4) is pretty old. Is there any substitute for subprocess that can be applied in this case??

Answer 1

Try commands module for py2.3.4, note that this module has been deprecated since py2.6:

Use commands.getoutput:

import commands
answer = commands.getoutput('./a.sh')
