linux - Using shell variables in Python script is not working -

i have shell script parameters being set like:
k.sh:

export var="value" export val2="value2" 

then have python script calling shell script , want use these enviornment variables
ex1.py:

import subprocess import os subprocess.call("source k.sh",shell=true) print os.environ["var"] 

but getting keyerror
how can use these shell variable in python script?

you source k.sh and run python one-liner print contents of os.environ json. use json.loads convert output dict in main process:

import subprocess import os import json pipe = subprocess.pipe output = subprocess.check_output(     ". ~/tmp/k.sh && python -c 'import os, json; print(json.dumps(dict(os.environ)))'",     shell=true) env = json.loads(output) print(env["var"]) 

yields
