Also fand ich dieses großartige Pong-Spiel, das von diesem Typ namens Ferrari kreiert wurde, und mir wurde die Aufgabe übertragen, es zu zweit zu spielen, mit zwei Punkten, aber ohne hohe Punktzahl. Ich habe viele Dinge ausprobiert, außer wenn ich einen zweiten Codeblock erstellt habe, der die Bewegungen steuert, die entweder vollständig ignoriert werden, oder wenn ich die ihm zugewiesene Aufwärtstaste drücke, wird der Code ganz nach oben gehen und nicht wieder herunterkommen.

## 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
