I need to source an environment file/Unix script from Python script to fetch the variables and use those variables in Python script.

I am able to source the environment file/Unix script but not able to fetch the value of the variable and use it.

My env file (env_var.env)looks like:-

export FLAG=YES; export TAG=A;

I want to source this file in my python script and need to print and use the values of FLAG and TAG.

Thanks in advance.

    So you do not want to source the file in your shell and then read the environment in Python, but to source the file _in Python_? That's a lot more difficult than the first way. – nnnmmm Feb 06 '18 at 17:15

    Possible duplicate of [Access environment variables from Python](https://stackoverflow.com/questions/4906977/access-environment-variables-from-python) - I'm guessing you mean you just want to access the environment variables. – kabanus Feb 06 '18 at 17:16
  • No, this env file will contain the environment variables and well the other variables like Folder_Path which could be /a/b/c. – AbhinavVaidya8 Feb 06 '18 at 17:38
  • You should probably parse it. Do you really need to run it through bash? – Josh Lee Feb 06 '18 at 17:39
  • @nnnmmm, I want to read the environment file directly from the Python script. – AbhinavVaidya8 Feb 06 '18 at 17:39
  • I tried creating a wrapper using Unix shell script and called my python script inside that wrapper script. This allowed me to source the variables using os.environ. – AbhinavVaidya8 Feb 10 '18 at 22:01

To solve this I am created an Unix wrapper on top of my python script and source all the variables in that wrapper. I was able to import all the variables in python script.

Try the following:

import os

os.system("source env_var.env && print(FLAG) && print(TAG)")
