Question

直接蝙蝠我是编程的新手，所以提前道歉提出一个基本问题。我已经研究过以前的答案，但我仍然卡住了。我正在解决以下问题：

问：为角色扮演游戏编写角色创建程序。应该为玩家提供一系列积分，用于四个属性：力量，健康，智慧，敏捷。玩家应该能够在任何属性上花费积分，并且还应该能够从属性中获取积分并将它们放回池中。

我找到了这个解决方案，但我不满意，因为它使用了书中尚未教授的术语，并且不包含列表或词典（整个章节都是关于此的，所以我希望结束 - 章节练习要求新知识）。 https://github.com/malmhaug/Py_AbsBegin/tree/master/Ch5E2_CreateCharacter

请给我一些帮助：这是迄今为止我所得到的。

提前致谢

Answer 1

元组是不可变的，因此您无法更改其中的值。

我建议你使用字典。

Answer 2

如果要修改character中的元素，则应使用字典，嵌套列表或列表元组，但不能使用元组列表
dict：

character = { 'Strength' : 0, 'Health' : 0, 'Wisdom' : 0, 'Dexterity' : 0 }

列表：

character = [ ['Strength', 0], ['Health', 0], ['Wisdom', 0], ['Dexterity', 0] ]

元组：

character = ( ['Strength', 0], ['Health', 0], ['Wisdom', 0], ['Dexterity', 0] )

现在，如果你想增加10点积分＆＃39;力量＆＃39; ，如果你想使用列表或元组，你可以{d}或character['Strength'] += 10 {/ 1}}

如何更改嵌套在列表中的元组元素
