os.environ.get return None, but echo works properly

Question

I have issue with "os.environ.get" command. I exported my variable using:

export MYVAR="123"

Then i used:

echo "$MYVAR"

And it returned my value. But when i am doing in python

print(os.environ.get('MYVAR'))

It returns None. For example:

print(os.environ.get('HOME'))

Works correctly. I tried using bashrc, zhrsc, bash_profile and it never works. I am using Linux Elementary 5.1. How can I solve this problem?

Looks like your export of the environment variable is only limited to the shell you are using. If you set the environment variable system-wide, it will be available to be read in your python code as well.

Set environment variable in /etc/environment for Unix based system
