Using UNIX Environment Variables From Python

Using environ from os package dose not work well when unsetting the variables. So write the unix commands in a korne shell script file and run it from python solves the issue.

import os
command = "unset TEST " + "\n" \
          "export GLOBAL_VALUE='global_value'" + "\n" \
                    "sample\n"
scr_name = "temp.tmp"
scr_file = open(scr_name, 'w') #write everything to a
scr_file.write(command)
scr_file.close()
os.chmod(scr_name, 0744) # mode -rwxr--r--
status = os.system(scr_name)
os.remove(scr_name)
