main()This was working before and now I am getting these three traceback errors:
Traceback (most recent call last):
File "G:\GuessingGame.py", line 104, in <module>
main()
File "G:\GuessingGame.py", line 101, in main
game.displayMenu() #Runs the menu, which then displays all the menu options
File "G:\GuessingGame.py", line 51, in displayMenu
list3[1]= int(list3[1])
IndexError: list index out of range
These errors only appear after I have saved a score to the scores.txt file, before adding a new score to it, everything works fine. I also need to rewrite it without functions/classes/methods/etc which will make it have a lot more lines of code.
