将 OOP 对象转换为 Python 中的文本

Question

我还是 OOP 菜鸟。

class ItemPrices:
def __init__(self, name=" ", exval=0, chval=0, curtype= " "):
    self.name = name
    self.exaltedValue = exval
    self.chaosValue = chval
    self.currType = curtype
  def Incubator_Values(self):
    response_API = requests.get("https://poe.ninja/api/data/itemoverview?league=Scourge&type=Incubator")
    data = response_API.text
    os.chdir(
        r"C:\Users\emosc\PycharmProjects\GithubPushs\psychescape_price_fetcher\psychescape_price_fetcher\values")
    parse_json = json.loads(data)
    with open("incubators.txt", "w") as file:
        file.write(" ")
    j = 0
    for i in parse_json["lines"]:
        list = []
        if (i["chaosValue"] > chaos_ex_ratio):
            self.name = i["name"]
            self.exaltedValue = i["exaltedValue"]
            self.currType = "Exalted Orb"
            print(self.name)
            list.append(self)
            j = j + 1
            print("Current iteration> ", j)
        else:
            self.name = i["name"]
            self.exaltedValue = i["chaosValue"]
            self.currType = "Chaos Orb"
            print(self.name)
            list.append(self)
            j = j + 1
            print("Current iteration> ", j)
        os.chdir(
            r"C:\Users\emosc\PycharmProjects\GithubPushs\psychescape_price_fetcher\psychescape_price_fetcher\values")
        with open("incubators.txt", "a") as file:
            file.write(str(list))
            file.write("\n")
            file.close()
    print("Incubator values has now storaged at IncubatorValues class and imported to incubators.txt")
    print(self)

以上是我尝试构建的 OOP 循环。 Class 并且 self 工作得很好，但是当我将值附加到列表并将其写入“incubators.txt”它只写入如下值：

[<__main__.ItemPrices object at 0x0000023A951ACFD0>]
[<__main__.ItemPrices object at 0x0000023A951ACFD0>]
[<__main__.ItemPrices object at 0x0000023A951ACFD0>]
[<__main__.ItemPrices object at 0x0000023A951ACFD0>]
[<__main__.ItemPrices object at 0x0000023A951ACFD0>]

当打印 self.name、self.exaltedValue 或 self.chaosValue 时，我可以看到我设法获取了字符串和整数，但只能将对象写入文件。我怎样才能将 strs 和 ints 写入文件？感谢您的帮助。

您可以将列表转换为 JSON 格式，然后写入文件。

使用此代码段：

result=json.dumps(list, default=lambda o: o.__dict__)

然后，你就可以把结果写入文件了
