Here's a simple example:: + + >>> from rich.prompt import Prompt + >>> name = Prompt.ask("Enter your name") + +The prompt may be given as a string (which may contain :ref:`console_markup` and emoji code) or as a :class:`~rich.text.Text` instance. + +You can set a default value which will be returned if the user presses return without entering any text:: + + >>> from rich.prompt import Prompt + >>> name = Prompt.ask("Enter your name", default="Paul Atreides") + +If you supply a list of choices, the prompt will loop until the user enters one of the choices:: + + >>> from rich.prompt import Prompt + >>> name = Prompt.ask("Enter your name", choices=["Paul", "Jessica", "Duncan"], default="Paul") + +In addition to :class:`~rich.prompt.Prompt` which returns strings, you can also use :class:`~rich.prompt.IntPrompt` which asks the user for an integer, and :class:`~rich.prompt.FloatPrompt` for floats. + +The :class:`~rich.prompt.Confirm` class is a specialized prompt which may be used to ask the user a simple yes / no question. Here's an example:: + + >>> from rich.prompt import Confirm + >>> is_rich_great = Confirm.ask("Do you like rich?") + >>> assert is_rich_great + +The Prompt class was designed to be customizable via inheritance.
