传递蟒蛇阵bash脚本（并通过bash的变量蟒蛇功能） [英] Passing python array to bash script (and passing bash variable to python function)

问题描述

我已经写它包含返回数组功能的Python模块。我希望能够访问从Python模块返回的字符串数组，并在bash脚本遍历，所以我可以遍历数组元素。

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.

例如：

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

def foo1(numargs):
    return [x for x in range(numargs)]

Bash脚本

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

我怎么能在bash实现这个？

How can I implement this in bash?.

版本信息：

2.6.5的Python
庆典：4.1.5

Python 2.6.5 bash: 4.1.5

推荐答案

第二个尝试 - 这一次的外壳采用一体化首当其冲

Second try - this time shell takes the integration brunt.

由于 foo.py 的包含此：

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

然后如下编写bash脚本：

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

的其余部分是从Python最终推动一体化的第一个答案。

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

的的Python 的

import os
import subprocess

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

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

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

的庆典的

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