Someone, please, can give me a light. I’m 100% lost.
I never used class before. I know something, but I really don’t know how to start this project.
I have to create a class with leader, I have to put the ‘self.leader = ’ where? and why?
I have to create a class with main with self.amount, self.description only?
Sorry about my English and to be a stupid.
Hey Max, first of all, you are not stupid!
Each one of us has already passed this road!
That said, its pretty hard to answer your question because we don’t know what you did and what exactly should be put on that line.
However, I have two   interesting links to you learn about Python classes, starting with the first one.
I hope it helps but if you still have questions just post on the forum.
