使用 PyQt5 "Updated" 从具有多个参数的函数中销毁一个 return 值
Destroy a return value from a function with multiple arguments using PyQt5 "Updated"
这是 S.N 提出的代码，非常感谢他，使用函数式编程。
它有一个严重的问题。如果它给 runItem 元组一些元素，例如 ("222", 15)，而这个元素在数据字典中不存在，它引用了这个方法 getbrutActifData() return 之前的值。事实上，我希望它是一个“0”。通常，我的程序的 runItem 是一个静态资产，包含假定在一般数据中的所有键。但是字典会根据数据而改变。如果您有任何建议，这是代码，谢谢。
如果字典中不存在，我将代码更新为在带有“0”的单元格 (n, -1) 中插入 item_b_1。

这是 S.N 提出的代码，非常感谢他，使用函数式编程。 它有一个严重的问题。如果它给 runItem 元组一些元素，例如 ("222", 15)，而这个元素在数据字典中不存在，它引用了这个方法 getbrutActifData() return 之前的值。事实上，我希望它是一个“0”。通常，我的程序的 runItem 是一个静态资产，包含假定在一般数据中的所有键。但是字典会根据数据而改变。如果您有任何建议，这是代码，谢谢。 如果字典中不存在，我将代码更新为在带有“0”的单元格 (n, -1) 中插入 item_b_1。
