사용자의 입력 선택은 제 사전 속성 키이고 있는지 확인 있는지 확인를 먼저 속성 선택 그들은 실제로 몇 가지 포인트의 큰 수 당신은 remove_selection 문자열의 두 번째 문자를 얻으려고 0

Answer 1

remove_selection[1]

이상을 가지고에서 점을 제거하기 위해 선택한

remove_selection = input("\nPress S to remove points from Strength. Press H to remove points from Health." 
            " Press W to remove points from Wisdom. Press D to remove points from Dexterity. " 
            "\nOtherwise, press any key to go back: ").upper() 

동안

이므로 remove_selection은 S, W, D 또는 H - 1 자입니다.
