Python library to build pretty command line user prompts ✨

You need input from a user, e.g. how an output file should be named or if he really wants to execute that dangerous operation? This library will help you make the input prompts easy to read and answer for the user.

Used and Supported by:

Quickstart

To install questionary, simply use pipenv (or pip, of course):

$ pipenv install questionary
✨🎂✨

Satisfaction guaranteed. Let's create a first question:

import questionary

questionary.select(
    "What do you want to do?",
    choices=[
        'Order a pizza',
        'Make a reservation',
        'Ask for opening hours'
    ]).ask()  # returns value of selection

This will create the following list, allowing the user to choose an option:

Documentation

Different question types

text

A free text input for the user.

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

password

A free text input for the user where the input is not shown but replaced with ***.

questionary.password("What's your secret?").ask()

confirm

A yes or no question. The user can either confirm or deny.

questionary.confirm("Are you amazed?").ask()

select

A list of items to select a choice from. The user can pick one option and confirm it.

questionary.select(
    "What do you want to do?",
    choices=[
        "Order a pizza",
        "Make a reservation",
        "Ask for opening hours"
    ]).ask()

rawselect

A list of items to select a choice from. The user can pick one option using shortcuts and confirm it.

questionary.rawselect(
    "What do you want to do?",
    choices=[
        "Order a pizza",
        "Make a reservation",
        "Ask for opening hours"
    ]).ask()

checkbox

A list of items to select multiple choices from. The user can pick none, one or multiple options and confirm the selection.

questionary.checkbox(
    'Select toppings',
    choices=[
        "foo",
        "bar",
        "bazz"
    ]).ask()

Additional Features

Skipping questions using conditions

Sometimes it is helpfull to e.g. provide a command line flag to your app to skip any prompts, to avoid the need for an if around any question you can pass that flag when you create the question:

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.

Alterative style to create questions using a configuration dictionary

Instead of creating questions using the python functions, you can also create them using a configuration dictionary.

questions = [
    {
        'type': 'text',
        'name': 'phone',
        'message': "What's your phone number",
    },
    {
        'type': 'confirm',
        'message': 'Do you want to continue?',
        'name': 'continue',
        'default': True,
    }
]

answers = prompt(questions)

The returned answers will be a dict containing the responses, e.g. {"phone": "0123123", "continue": False, ""}. The questions will be prompted one after another and prompt will return once all of them are answered.

Styling your prompts with your favorite colors

You can customize all the colors used for the prompts. Every part of the prompt has an identifier, which you can use to style it. Let's create our own custom style:

from prompt_toolkit.styles import Style

custom_style_fancy = Style([
    ('qmark', 'fg:#673ab7 bold'),       # token in front of the question
    ('question', 'bold'),               # question text
    ('answer', 'fg:#f44336 bold'),      # submitted answer text behind the question
    ('pointer', 'fg:#673ab7 bold'),     # pointer used in select and checkbox prompts
    ('highlighted', 'fg:#673ab7 bold'), # pointed-at choice in select and checkbox prompts if use_pointer=False
    ('selected', 'fg:#cc5454'),         # style for a selected item of a checkbox
    ('separator', 'fg:#cc5454'),        # separator in lists
    ('instruction', ''),                # user instructions for select, rawselect, checkbox
    ('text', ''),                       # plain text
    ('disabled', 'fg:#858585 italic')   # disabled choices for select and checkbox prompts
])

To use our custom style, we need to pass it to the question type:

questionary.text("What's your phone number", style=custom_style_fancy).ask()

It is also possible to use a list of token tuples as a Choice title. This example assumes there is a style token named bold in the custom style you are using:

Choice(
    title=[
        ('class:text', 'plain text '),
        ('class:bold', 'bold text')
    ]
)

As you can see it is possible to use custom style tokens for this purpose as well. Note that Choices with token tuple titles will not be styled by the selected or highlighted tokens. If not provided, the value of the Choice will be the text concatenated ('plain text bold text' in the above example).

How to Contribute

1. Check for open issues or open a fresh issue to start a discussion around a feature idea or a bug. There is a Contributor Friendly tag for issues that should be ideal for people who are not very familiar with the codebase yet.
2. Fork the repository on GitHub to start making your changes to the master branch (or branch off of it).
3. Write a test which shows that the bug was fixed or that the feature works as expected.
4. Send a pull request and bug the maintainer until it gets merged and published. 🙂
