将键盘码转为字符：

keyboard_code = "63" # 键盘码（不带问号）
character = chr(int(keyboard_code)) # 将键盘码转换为字符
print("键盘码带问号后的结果：", character)

将大写字母转为小写字母：

# 接收键盘输入并转换成小写字母的ASCII码
input_char = input("请输入一个小写字母：")
ascii_code = ord(input_char) - 32 # ASCII码值加上32得到大写字母的ASCII码
print("该小写字母的ASCII码为：", ascii_code)

通过qt确认特殊按钮键盘码：

if key == Qt.Key_Shift:
            return KeyEvent.ShiftKey
        elif key == Qt.Key_Control:
            return KeyEvent.ControlKey
        elif key == Qt.Key_Alt:
            return KeyEvent.AltKey
        elif key == Qt.Key_Space:
            return KeyEvent.SpaceKey
        elif key == Qt.Key_Meta:
            return KeyEvent.MetaKey
        elif key == Qt.Key_Enter or key == Qt.Key_Return:
            return KeyEvent.EnterKey
        elif key == Qt.Key_Up:
            return KeyEvent.UpKey
        elif key == Qt.Key_Down:
            return KeyEvent.DownKey
        elif key == Qt.Key_Left:
            return KeyEvent.LeftKey
        elif key == Qt.Key_Right:
            return KeyEvent.RightKey
        elif key == Qt.Key_Minus:
            return KeyEvent.MinusKey
        elif key == Qt.Key_Underscore:
            return KeyEvent.UnderscoreKey
        elif key == Qt.Key_Plus:
            return KeyEvent.PlusKey
        elif key == Qt.Key_Equal:
            return KeyEvent.EqualKey
