Returns: Bool: True if at least one environment variable is set else False If both `dotenv_path` and `stream` are `None`, `find_dotenv()` is used to find the .env file with it's default parameters. If you need to change the default parameters of `find_dotenv()`, you can explicitly call `find_dotenv()` and pass the result to this function as `dotenv_path`.
