How can I SET an OS key in windows to have access to it later in Python?

Question

I'm trying to imitate export Key_value="My value" from Linux on my Windows computer but in my terminal it doesn't work. I saw that maybe I should use SET instead export but when I print my environment dictionary my key and value aren't there, only the normal OS values.

The command in the cmd console is:

setx your_key_value "your value"

You can do it manually too if you go to "environmental variables" using windows menu and typing that, then go to environmental variables and add the one that you want to insert.

My problem then was that I set it but it was not reflected in the os.environment dictionary. I restarted my computer and tried again and there it was. I think that OS variables are set only when you start your computer.
