python - 数据输出和内部函数不一样

Question

我目前遇到一个问题，我试图将数据存储在列表中（使用数据类）。当我在函数 (PullIncursionData()) 的列表中打印数据时，它会以一定数量的数字进行响应（从不一样，由于它的性质是不可能的）。在调用它以存储它后打印它时，它以 Var 的形式返回，它以某种方式只打印相同的数字。

我无法分享这些数字，因为它们会使用 EVE Online 的 API 进行更新，所以唯一的方法是在本地运行它并自己阅读第一个列表。

存储库在这里：https ://github.com/AtherActive/EVEAPI-Demo

• 小心！在 main.py（有问题的文件）（下面是一段代码）内有更多功能。第 90 行及以后的所有函数都很重要，对于这个问题，其余的可以忽略，因为它们不与其他函数交互。
