I am trying to make a game with Python, but I ask a question because it is difficult to make. The question is, when I press the button join, I check if the value of entry is duplicated and if not, I save it in a file called db.txt. I get an error. What should I do?
the fruit of my efforts

These are my codes. What I want is to check if the entry value is duplicated here, and if it is not duplicated, put it in the txt file and cancel it if it is duplicated
