python capture environment variables

Question

this bash script can catch all the environment variables which are set when data is passed through STDIN eg such as:

echo "Hello" | ./script.sh

script.sh

#!/bin/bash

CAPTURE_FILE=/var/log/capture_data
env >> ${CAPTURE_FILE}
exit 1

it there any way i can do same in python??

RESOLVED:

this is the resultant python version..

#!/usr/bin/env python

import os
import sys

def capture():

    log = os.environ
    data = open("/tmp/capture.log", "a")
    for key in log.keys():
        data.write((key))
        data.write(" : ")
        for n in log[key]:
            data.write('%s' % ((n)))
        data.write("\n")
    data.close()
    sys.exit(1)

def main():

    capture()

if __name__ == "__main__":
    main()

os.environ is a mapping that contains all environment variables and their values.
