Function load_dotenv

src/dotenv/main.py:383–429

Parse a .env file and then load all the variables found as environment variables. 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

    dotenv_path: Optional[StrPath] = None,

    verbose: bool = False,
    override: bool = False,
    interpolate: bool = True,
    encoding: Optional[str] = "utf-8",

    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.
    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`.

    If the environment variable `PYTHON_DOTENV_DISABLED` is set to a truthy value,
    .env loading is disabled.
