从i读取JSON文件并创建对象

Question

我有一个程序，随机产生10个RPG字符。我实现了将它们保存到characterFile.json的功能，该文件中包含的内容如下：

[
{
    "health": 100,
    "name": "da fu en ",
    "power": 30,
    "sAttackPwr": 60,
    "speed": 10,
    "type": "Elf"
},
{
    "health": 100,
    "name": "tuk ar da ",
    "power": 90,
    "sAttackPwr": 40,
    "speed": 50,
    "type": "Dragon"
},
{
    "health": 100,
    "name": "tuk el low ",
    "power": 30,
    "sAttackPwr": 60,
    "speed": 10,
    "type": "Elf"
},
{
    "health": 100,
    "name": "ant en ant ",
    "power": 90,
    "sAttackPwr": 40,
    "speed": 50,
    "type": "Dragon"
},
{
    "health": 100,
    "name": "tuk en el ",
    "power": 90,
    "sAttackPwr": 40,
    "speed": 50,
    "type": "Dragon"
},
{
    "health": 100,
    "name": "ar da ar ",
    "power": 90,
    "sAttackPwr": 40,
    "speed": 50,
    "type": "Dragon"
},
{
    "health": 100,
    "name": "kar ing tuk ",
    "power": 30,
    "sAttackPwr": 60,
    "speed": 10,
    "type": "Elf"
},
{
    "health": 100,
    "name": "da cha ing ",
    "power": 50,
    "sAttackPwr": 70,
    "speed": 30,
    "type": "Wizard"
},
{
    "health": 100,
    "name": "da cha low ",
    "power": 50,
    "sAttackPwr": 70,
    "speed": 30,
    "type": "Wizard"
},
{
    "health": 100,
    "name": "da cha tuk ",
    "power": 30,
    "sAttackPwr": 60,
    "speed": 10,
    "type": "Elf"
}
]

（粘贴到SO中时格式错误，但在文件中的设置方式是正确的）

我希望能够读回这个程序，从那个列表创建对象。在

到目前为止，我将文件读回程序：

^{pr2}$

characterClass是我用来实例化对象的类：

# Base Class for creating an RPG character
class character:
    # __init__ method, creates the name, type, health properties
    def __init__(self, charName, charType, charHealth):
        self.name = charName
        self.type = charType
        self.health = charHealth


class characterClass(character):
    def __init__(self, charName, charType, charHealth, charPower, charSAttackPwr, charSpeed):
        character.__init__(self, charName, charType, charHealth)
        self.power = charPower
        self.sAttackPwr = charSAttackPwr
        self.speed = charSpeed

运行此代码时，出现以下错误：

TypeError: list indices must be integers or slices, not dict

现在，我理解这个错误的方式是，我试图在一个列表中寻找一个索引，但是却把整个字典发送给它，它不能变成一个整数

为了使用循环将这个读回我的程序，我遗漏了什么？在

Answer 1

这里，^{cd1>}是实际字符dict，而不是索引：

for x in data:

尝试类似的方法：

^{pr2}$

我在这里还添加了缺少的引号，我建议使用比^{{cd2>}更具描述性的名称。^{cd3>}怎么样？Python类通常以^{{cd4>}命名，因此^{{cd5>}和^{cd6>}可能比^{{cd7>}和^{{cd8>}更好。Python的official style guide在这里可能会有所帮助。

最后，我认为您不需要^{cd9>}。

Answer 2

x不是索引，而是dict本身。For循环遍历从JSON文件加载到数据中的每个条目。正确的代码行应该是：

gameChars = characterClass(x['name'], x['type'], x['health'], x['power'], x['sAttackPwr'], x['speed'])
