    A wrapper class around :class:`~prompt_toolkit.shortcuts.PromptSession`.

    Args:
        message: The question to ask the user.
            Refer to :ref:`pages/dynamic:message` documentation for more details.
        style: An :class:`InquirerPyStyle` instance.
            Refer to :ref:`Style <pages/style:Alternate Syntax>` documentation for more details.
        vi_mode: Use vim keybinding for the prompt.
            Refer to :ref:`pages/kb:Keybindings` documentation for more details.
        default: Set the default text value of the prompt.
            Refer to :ref:`pages/dynamic:default` documentation for more details.
        qmark: Question mark symbol. Custom symbol that will be displayed infront of the question before its answered.
        amark: Answer mark symbol. Custom symbol that will be displayed infront of the question after its answered.
        instruction: Short instruction to display next to the question.
        long_instruction: Long instructions to display at the bottom of the prompt.
        validate: Add validation to user input.
            Refer to :ref:`pages/validator:Validator` documentation for more details.
        invalid_message: Error message to display when user input is invalid.
            Refer to :ref:`pages/validator:Validator` documentation for more details.
        transformer: A function which performs additional transformation on the value that gets printed to the terminal.
            Different than `filter` parameter, this is only visual effect and won’t affect the actual value returned by :meth:`~InquirerPy.base.simple.BaseSimplePrompt.execute`.
            Refer to :ref:`pages/dynamic:transformer` documentation for more details.
        filter: A function which performs additional transformation on the result.
            This affects the actual value returned by :meth:`~InquirerPy.base.simple.BaseSimplePrompt.execute`.
            Refer to :ref:`pages/dynamic:filter` documentation for more details.
        keybindings: Customise the builtin keybindings.
            Refer to :ref:`pages/kb:Keybindings` for more details.
        wrap_lines: Soft wrap question lines when question exceeds the terminal width.
        raise_keyboard_interrupt: Raise the :class:`KeyboardInterrupt` exception when `ctrl-c` is pressed. If false, the result
            will be `None` and the question is skiped.
        mandatory: Indicate if the prompt is mandatory. If True, then the question cannot be skipped.
        mandatory_message: Error message to show when user attempts to skip mandatory prompt.
        session_result: Used internally for :ref:`index:Classic Syntax (PyInquirer)`.
        input: Used internally and will be removed in future updates.
        output: Used internally and will be removed in future updates.

    Examples:
        >>> from InquirerPy import inquirer
        >>> result = inquirer.secret(message="Password:").execute()
        >>> print(f"Password: {result}")
        Password: asdf123
