Passing python array to bash script (and passing bash variable to python function)

bash, python

Solution

Second try - this time shell takes the integration brunt.

Given foo.py containing this:

def foo():
        foo = ('String', 'Tuple', 'From', 'Python' )
        return foo

Then write your bash script as follows:

#!/bin/bash
FOO=`python -c 'from foo import *; print " ".join(foo())'`
for x in $FOO:
do
        echo "This is foo.sh: $x"
done

The remainder is first answer that drives integration from the Python end.

Python

import os
import subprocess

foo = ('String', 'Tuple', 'From', 'Python' )

os.putenv('FOO', ' '.join(foo))

subprocess.call('./foo.sh')

bash

#!/bin/bash
for x in $FOO
do
        echo "This is foo.sh: $x"
done

Problem

I have written a Python module which contains functions that return arrays. I want to be able to access the string arrays returned from the python module, and iterate over in a bash script, so I may iterate over the array elements. For example: Python module (mymod) ``` def foo(): return ('String', 'Tuple', 'From', 'Python' ) def foo1(numargs): return [x for x in range(numargs)] ``` Bash script ``` foo_array = .... # obtain array from mymod.foo() for i in "${foo_array[@]}" do echo $i done foo1_array = .... # obtain array from mymod.foo1(pass arg count from bash) for j in "${foo1_array[@]}" do echo $j done ``` How can I implement this in bash?. version Info: Python 2.6.5 bash: 4.1.5
