Personal Comments
In linux you can install a program called fortune. This program gives you a random wisdom each time you execute it. I thought about making a game, where you have to do something before you can read some wise words.
This is "the biggest" program I have written so far. I tried to practise object oriented programming by developing an idea and model the individual structures by using OOP-concepts. So I would like to read comments how to improve the structure of the code. This game also was written by me in a simplified form in Java and in C, but now I also wanted to try Python. So if you can tell me where there is a better way, a "Python way to do something" for elements of my program, i would be thankful.
I tested the program till i have not found bugs anymore. I hope you will also dont find any bugs.
Thank you for your attention!
Game Description
You have to solve mathmatical exercises. You gain Experience points, rank points and gold. You can buy attribute upgrades for speed up the reward gaining and unlock new wisdoms from wise persons.
