export in_server=${OUT_SERVER}
export in_database=${OUT_DATABASE}
OUT_SERVER = url
OUT_DATABASE = database name

but its not working for me. How can i call python variables in bash script?

Answer 1

If you have something like this in your bash script

echo "var=$var"

then from python, you can call

#! /usr/bin/env python3

import subprocess

env = {'var': 'val'}
subprocess.run(['myscript'], env=env)

and you'll receive

var=val

Answer 2

in your python script you can set a environment variable,

import os

#Set environment variables
os.environ['VARIABLE'] = 'VALUE'

in your bash script in the same terminal session, you can call the environment variable.
