bool_quetion

Python-module for asking yes/no or accept/cancel questions.

Installing

Install from PyP

pip install bool_quetion

Using a virtual environment.

Create virtual environment:

python3 -m venv .venv

Activate virtual environment:

source .venv/bin/activate

Install bool_quetion:

pip install bool_quetion

If you're not using a virtual environment and want to install packages globally, you'll likely need --break-system-packages to bypass restrictions that protect system:

pip install bool_quetion --break-system-packages

Install from APT repositories

As root or using sudo

Add APT repositories:

echo "deb https://pablinet.github.io/apt ./" > /etc/apt/sources.list.d/pablinet.list

Add APT Key:

wget -O /etc/apt/trusted.gpg.d/pablinet.gpg https://pablinet.github.io/apt/pablinet.gpg

Upload APT repositories:

apt update

Install bool_quetion:

apt install python3-bool-quetion

Using the code in Python 3.x

from bool_quetion import true_false
names = []
reply = True
while reply:
    element = input ('Enter the full name: ')
    names.append(element)
    for name in names:
        print (name)
        reply = true_false('Do you wish to continue?', ['Yes or', 'no'])
else:
    reply = True

It is also possible to customize the error message and highlight the characters that can be entered:

reply = true_false('Do you wish to continue?', ['Yes or', 'no'], True)
reply = true_false('Continue?', ['Yes or', 'no'], 'Error Key', True)

BONUS TRACK

Use this library in Bash.

#!/usr/bin/env python3
from sys import argv, exit
from bool_quetion import true_false

if 3 > len(argv) or len(argv) > 5:
    print('Error in the number of arguments.')
    exit(255)
arguments = argv[1:].copy()
arguments[1] = arguments[1].split('%')
err_number = 1
if len(arguments[1]) == 3 and arguments[1][2].isdecimal():
    err_number = int(arguments[1][2])
    arguments[1].pop()
if len(arguments) in (3, 4):
    if arguments[-1].lower() in ('true', 'false'):
        arguments[-1] = arguments[-1].lower() == 'true'
exit(0 if true_false(*arguments) else err_number)

Add execution permissions:

chmod +x true-false

Run the script:

./true-false 'Do you wish to continue?' 'Yes or%No'
./true-false 'Do you wish to continue?' 'Yes or%No' 'Bad key'
./true-false 'Do you wish to continue?' 'Yes or%No' 'Bad key' true

Run script with custom error code:

./true-false 'Do you wish to continue?' 'Yes or%No%5'
./true-false 'Do you wish to continue?' 'Yes or%No%5' 'Bad key'
./true-false 'Do you wish to continue?' 'Yes or%No%5' 'Bad key' true
