单击按钮后如何从 ComboBox 更改变量值？
How to change a variables value from a ComboBox after a button being clicked?
我正在研究未加权的 GPA 计算器，我对 (Py)Qt Designer 应用程序有点陌生。我 运行 遇到了一个问题，我不知道如何从 ComboBoxes 中获取结果并将其计算到名为 gpa 的变量中。
基本上，这就是我想要发生的事情：
如果 letter_grade1 ComboBox 是 A+，那么它会将 4.0 添加到 gpa
如果 letter_grade2 ComboBox 是 B 则它会将 3.0 添加到 gpa
之后，它会除以 5，因为有 5 个组合框正在计算结果被打印出来，这一切都发生在 submit_grades 按钮被点击后。

假设您采样的 .py 文件名为 design.py 您必须创建另一个 .py 文件，其逻辑是避免在单个文件中包含多行代码。
解决这个问题，想法是查看 Table 其中选项通过字典与值相关，然后计算平均值。
