Is adding Flask env vars to the virtualenv's activate script OK?

Question

I\'m working on my Flask project in a virtualenv. Every time I start a new terminal, I have to reinitialize these Flask environment variables:

export FLASK

Modifying venv/bin/activate file is working for you because the environment variable is getting defined inside the virtual environment. When you're using python3 -m venv venv the environment variables are not present in the new virtual environment. Instead of modifying the activate file, you can instead make a shell script which:

1. Runs venv/bin/activate
2. Defines the environment variables
3. Runs the server

First, I tried writing a Python script that set them, but after research, I realized it was not possible(?).

You could use os.environ to do the same from within, but a shell script is better.
