Unable to get environment variables using os python

Question

I recently created two environment variables in my terminal as shown below

export SPARK_HOME=\'/opt/spark/\'
export HAIL_HOME=\'/home/ABCD/.pyenv/versions/3.7.2/e         


        

Answer 1

I realized that it doesn't produce output for HAIL_HOME because it is installed in my virtual environment. (see .pyenv which is a hidden folder for my virtual environment`)

However, if anyone can confirm this it's even better
