本项目使用Python实现，仅使用了copy模块和time模块，代码中大量应用了for循环、if条件判断、列表（list）方法和递归，适合Python初学者巩固Python基础；在config文件中根据数独题目，更新数独列表的值；然后执行soduku.py，就会输出该数独题目对应的答案。(This project is based on Python , and I used no modules other than copy and time. The code use a lot of Basic knowledge of Python such as for cycle , if , list method and Recursive . It seems that this project can help Python beginner pratise Basic knowledge of Python.)
