Why is the variable not added to the virtual environment?

Question

Django

Python2.7, windows10
Hello everyone!
I add to the activate file of the virtual environment, which is in Scripts, the lines
test_value="awdaDWAD"
export test_value
Next, I activate the virtual environment, go to the shell, import os, then print os.getenv('test_value').
I get None.
Why?
How to add variables to virtual environment?

Answer 1

I usually do this:
activate :
export SOME_KEY = 'foobar'
settings.py :
SOME_KEY = os.getenv('SOME_KEY')
or use dotenv
