Parameters: dotenv_path: Absolute or relative path to .env file. stream: Text stream (such as `io.StringIO`) with .env content, used if `dotenv_path` is `None`. verbose: Whether to output a warning the .env file is missing. override: Whether to override the system environment variables with the variables from the `.env` file. encoding: Encoding to be used to read the file.

The returned dict will have `None` values for keys without values in the .env file. For example, `foo=bar` results in `{"foo": "bar"}` whereas `foo` alone results in `{"foo": None}` Parameters: dotenv_path: Absolute or relative path to the .env file. stream: `StringIO` object with .env content, used if `dotenv_path` is `None`. verbose: Whether to output a warning if the .env file is missing. encoding: Encoding to be used to read the file.
