rich.prompt¶

class rich.prompt.Confirm(prompt: Union[str, rich.text.Text] = '', *, console: Optional[rich.console.Console] = None, password: bool = False, choices: Optional[List[str]] = None, show_default: bool = True, show_choices: bool = True)[source]¶

A yes / no confirmation prompt.

Example

>>> if Confirm.ask("Continue"):
        run_job()

process_response(value: str) → bool[source]¶: Convert choices to a bool.

render_default(default: rich.prompt.DefaultType) → rich.text.Text [source]¶: Render the default as (y) or (n) rather than True/False.

response_type¶: alias of bool

class rich.prompt.FloatPrompt(prompt: Union[str, rich.text.Text] = '', *, console: Optional[rich.console.Console] = None, password: bool = False, choices: Optional[List[str]] = None, show_default: bool = True, show_choices: bool = True)[source]¶

A prompt that returns a float.

Example

>>> temperature = FloatPrompt.ask("Enter desired temperature")

response_type¶: alias of float

class rich.prompt.IntPrompt(prompt: Union[str, rich.text.Text] = '', *, console: Optional[rich.console.Console] = None, password: bool = False, choices: Optional[List[str]] = None, show_default: bool = True, show_choices: bool = True)[source]¶

A prompt that returns an integer.

Example

>>> burrito_count = IntPrompt.ask("How many burritos do you want to order")

response_type¶: alias of int

exception rich.prompt.InvalidResponse(message: Union[str, rich.text.Text])[source]¶

Exception to indicate a response was invalid. Raise this within process_response() to indicate an error and provide an error message.

Parameters: message (Union[str, Text]) – Error message.

class rich.prompt.Prompt(prompt: Union[str, rich.text.Text] = '', *, console: Optional[rich.console.Console] = None, password: bool = False, choices: Optional[List[str]] = None, show_default: bool = True, show_choices: bool = True)[source]¶

A prompt that returns a str.

Example

>>> name = Prompt.ask("Enter your name")

response_type¶: alias of str

class rich.prompt.PromptBase(prompt: Union[str, rich.text.Text] = '', *, console: Optional[rich.console.Console] = None, password: bool = False, choices: Optional[List[str]] = None, show_default: bool = True, show_choices: bool = True)[source]¶

Ask the user for input until a valid response is received. This is the base class, see one of the concrete classes for examples.

Parameters

prompt (TextType, optional) – Prompt text. Defaults to “”.
console (Console, optional) – A Console instance or None to use global console. Defaults to None.
password (bool, optional) – Enable password input. Defaults to False.
choices (List[str], optional) – A list of valid choices. Defaults to None.
show_default (bool, optional) – Show default in prompt. Defaults to True.
show_choices (bool, optional) – Show choices in prompt. Defaults to True.

classmethod ask(prompt: Union[str, Text] = '', *, console: Optional[rich.console.Console] = 'None', password: bool = 'False', choices: Optional[List[str]] = 'None', show_default: bool = 'True', show_choices: bool = 'True', default: rich.prompt.DefaultType, stream: Optional[TextIO] = 'None') → Union[rich.prompt.DefaultType, rich.prompt.PromptType][source]¶

classmethod ask(prompt: Union[str, Text] = '', *, console: Optional[rich.console.Console] = 'None', password: bool = 'False', choices: Optional[List[str]] = 'None', show_default: bool = 'True', show_choices: bool = 'True', stream: Optional[TextIO] = 'None') → rich.prompt.PromptType

Shortcut to construct and run a prompt loop and return the result.

Example

>>> filename = Prompt.ask("Enter a filename")

Parameters

prompt (TextType, optional) – Prompt text. Defaults to “”.
console (Console, optional) – A Console instance or None to use global console. Defaults to None.
password (bool, optional) – Enable password input. Defaults to False.
choices (List[str], optional) – A list of valid choices. Defaults to None.
show_default (bool, optional) – Show default in prompt. Defaults to True.
show_choices (bool, optional) – Show choices in prompt. Defaults to True.
stream (TextIO, optional) – Optional text file open for reading to get input. Defaults to None.

check_choice(value: str) → bool[source]¶

Check value is in the list of valid choices.

Parameters: value (str) – Value entered by user.
Returns: True if choice was valid, otherwise False.
Return type: bool

classmethod get_input(console: rich.console.Console, prompt: Union[str, rich.text.Text], password: bool, stream: Optional[TextIO] = None) → str[source]¶

Get input from user.

Parameters

console (Console) – Console instance.
prompt (TextType) – Prompt text.
password (bool) – Enable password entry.

Returns

String from user.

Return type

str

make_prompt(default: rich.prompt.DefaultType) → rich.text.Text [source]¶

on_validate_error(value: str, error: rich.prompt.InvalidResponse) → None[source]¶

Called to handle validation error.

Parameters

value (str) – String entered by user.
error (InvalidResponse) – Exception instance the initiated the error.

pre_prompt() → None[source]¶: Hook to display something before the prompt.

process_response(value: str) → rich.prompt.PromptType[source]¶

Process response from user, convert to prompt type.

Parameters: value (str) – String typed by user.
Raises: InvalidResponse – If value is invalid.
