Can I read an `export`ed variable from a python script?

Question

I have a bash script and a python script:

script

#!/bin/bash
a=10
export a
python script.py

script.py

# access 'a' somehow

Is there a way to access the exported variables from python?

Answer 1

Exported variables are set as environment variables. Use os.environ (a dictionary) to read these in your Python script:

import os

a = os.environ['a']
