How to implement 24-point game with Python+Pygame

Game introduction

(1) What is a 24-point game

Board and card puzzle game, the result is required to be equal to twenty-four

(2)Game rules

Pick any 4 numbers (1--10), and use addition, subtraction, multiplication, and division (parentheses can be added) to calculate the number to 24. Each number must be used once and only once. "Counting 24 points" is an intellectual game that exercises thinking. You should also pay attention to the technical issues in calculation. When calculating, it is impossible for us to try different combinations of the four numbers on the card, let alone mess around.

Example: 3, 8, 8, 9

Answer: 3×8÷(9-8)=24
