questionary

questionary is a Python library based on Prompt Toolkit to effortlessly building pretty command line interfaces. It makes it very easy to query your user for input.

Installation⚑

pip install questionary

Usage⚑

Asking a single question⚑

Questionary ships with a lot of different Question Types to provide the right prompt for the right question. All of them work in the same way though.

import questionary

answer = questionary.text("What's your first name").ask()

Since our question is a text prompt, answer will contain the text the user typed after they submitted it.

Asking Multiple Questions⚑

You can use the form() function to ask a collection of Questions. The questions will be asked in the order they are passed to questionary.form.

import questionary

answers = questionary.form(
    first=questionary.confirm("Would you like the next question?", default=True),
    second=questionary.select("Select item", choices=["item1", "item2", "item3"]),
).ask()

The output will have the following format:

{'first': True, 'second': 'item2'}

The prompt() function also allows you to ask a collection of questions, however instead of taking Question instances, it takes a dictionary:

import questionary

questions = [
    {
        "type": "confirm",
        "name": "first",
        "message": "Would you like the next question?",
        "default": True,
    },
    {
        "type": "select",
        "name": "second",
        "message": "Select item",
        "choices": ["item1", "item2", "item3"],
    },
]

questionary.prompt(questions)

Conditionally skip questions⚑

Sometimes it is helpful to be able to skip a question based on a condition. To avoid the need for an if around the question, you can pass the condition when you create the question:

import questionary

DISABLED = True
response = questionary.confirm("Are you amazed?").skip_if(DISABLED, default=True).ask()

If the condition (in this case DISABLED) is True, the question will be skipped and the default value gets returned, otherwise the user will be prompted as usual and the default value will be ignored.

Exit when using control + c⚑

If you want the question to exit when it receives a KeyboardInterrupt event, use unsafe_ask instead of ask.

Question types⚑

The different question types are meant to cover different use cases. The parameters and configuration options are explained in detail for each type. But before we get into to many details, here is a cheatsheet with the available question types:

• Use Text to ask for free text input.

• Use Password to ask for free text where the text is hidden.

• Use File Path to ask for a file or directory path with autocompletion.

• Use Confirmation to ask a yes or no question.

>>> questionary.confirm("Are you amazed?").ask()
? Are you amazed? Yes
True

• Use Select to ask the user to select one item from a beautiful list.

• Use Raw Select to ask the user to select one item from a list.

• Use Checkbox to ask the user to select any number of items from a list.

• Use Autocomplete to ask for free text with autocomplete help.

Check the examples to see them in action and how to use them.

Styling⚑

Don't highlight the selected option by default⚑

If you don't want to highlight the default choice in the select question use the next style:

from questionary import Style

choice = select(
    "Question title: ",
    choices=["a", "b", "c"],
    default="a",
    style=Style([("selected", "noreverse")]),
).ask()

Testing⚑

To test questionary code, follow the guidelines of testing prompt_toolkit.
