所以我发现了这个叫法拉利的人创造的伟大的乒乓球比赛，我被赋予了让两人打出两分但没有高分的任务。我已经尝试了很多东西，除了当我制作第二个控制运动的代码块时，它要么被完全忽略，要么我会按下它分配的向上按钮，它会一直向上并且不会回来。

## decimal is for numbers and arithmatic that use irrational numbers
## Tkinter is the graphical interface for the program
## tkFont is the window that pops up
## os is operating system
## sys is system
## there are 2 different variables for player 1 and player 2 because one variable is a variable for a number, the other creates the rectangle(the actual paddle)
## these are just variables that represent numbers
