How to manage zappa settings to dev environment using django

Question

What is the best practices to manage dev enviroment using zappa? Currently I have my zappa_settings.json in my project and inside it I have api urls, keys etc. when I deploy It to AWS these keys will be used correctly like:

API_KEY = os.getenv('API_KEY')

the code above will get the API_KEY from my zappa_seetings.json

{
    "prod": {
        "API_KEY": "example 2938u2983j0fy28394yf2j98340j20934"
    }
}

But what if I want to run the code locally? I'll need to create a .env file with the same enviroment keys and every time I change the zappa_settings.json file I'll need to change the .env file too? If there is a different way to do it, I would like to know.
