This is a simple Python script which tests if dice are fair or biased, using the Chi-Squared test.
This script is forked from mindbane's Dice-Tester. Functionally, it is almost identical to mindbane's script, but written in Python instead of Visual Basic. I wanted a Python version of the script because I use Linux, and Visual Basic scripts only work on Windows as far as I know.
I translated the original script into Python, with the help of Google Gemini. The underlying maths and the way it works is identical to mindbane's script, but I made a few changes:
- Made the script display how many input rolls you have entered so far. I found that entering 100+ numbers into the terminal with no indication of how many more I had to go was a little frustrating, and wanted to see my progress.
- Dice numbers start from 1 instead of 0, to make things less confusing (ie. if you have a 12 sided dice, "12" is a valid roll, and "0" is not)
- Updated some of the prompts to be a little clearer
- Added basic handling of invalid input
- Tidied up and Python-ified the code (Gemini translated it without any issues, but the output code had bad style and was not very Pythonic. Gemini also made use of the
numpylibrary, which was unnecessary for such a simple script. AI is powerful, but still has plenty of room for improvement. By using default Python features instead ofnumpy, I made the script work without having to set up a virtual environment or install additional libraries first)
To run the Dice Tester script, enter the following command in your terminal:
python3 dice_tester.py
If the file permissions of dice_tester.py allow you to execute the file as a program, you can instead use:
./dice_tester.py
(On Mac and Linux, to change the file permissions of dice_tester.py and allow it to be executed directly, use the command chmod +x dice_tester.py)
The script will walk you through the steps to test your dice and do the maths for you.
