PyFuzzyBool

Additional boolean values: KindaTrue, KindaFalse, VeryTrue, and VeryFalse. (This is a joke project.)

Installation

To install with pip, run:

pip install pyfuzzybool

Quickstart Guide

In the Python language, the bool data type is a subclass of integers. The values True and False are literally the same as the integer values 1 and 0: you can use them any way you use integers: True + True + False + True evaluates to 3 and 'Hello[True]' evaluates to 'e'.

There is also a concept of "truthy" and "falsey" values in Python: 0, 0.0, blank strings, empty lists/dictionaries/tuples, and others are "falsey" values; when passed to bool() they will evaluate to the bool value False. All other values are "truthy" and when passed to bool() will evaluate to True.

Similarly, fuzzybool(1) and fuzzybool(0) will evaluate to True and False, but passing a float or int larger than 1.0 evaluates to VeryTrue, while passing a value less than 0.0 evaluates to VeryFalse. Passing a value between 0.0 and 1.0 will evaluate to KindaTrue half the time and KindaFalse the other time.

Here's some examples in the interactive shell:

>>> from pyfuzzybool import *
>>> KindaTrue == KindaFalse
True
>>> KindaTrue == True
False
>>> VeryTrue == True
True
>>> VeryFalse == False
True
>>> KindaFalse == False
False
>>> fuzzybool(1)
fuzzybool(True)
>>> fuzzybool(0.9)
KindaTrue
>>> fuzzybool(0)
fuzzybool(False)
>>> fuzzybool(-1)
VeryFalse
>>> fuzzybool(1.1)
VeryTrue
>>> fuzzybool()
KindaFalse
>>> KindaFalse < True
True
>>> KindaFalse > False
True
>>> KindaFalse <= KindaTrue
True

I think a lot of these can be changed. Should KindaTrue == True evaluate to True? Or should it evaluate to KindaTrue? Or evaluate half the time to KindaTrue and the other half KindaFalse?

This project is a joke, but this opens up a lot of issues to think about (if you have nothing better to do). After all, mathematics is just a bunch of made up, arbitrary rules about how to operate on abstract symbols. Math just happens to turn out to be unreasonably effective in science.
