为什么这些方法不像我期望的那样工作？我可以立即打印一条线 但是，该方法似乎没有其他功能。
我正在尝试
代码：

#for faster inspection and when attending to multiple DCP inspections.

答案 0 :(得分：2)
对我来说，似乎没有一个变量以self.开头，这意味着你没有任何类成员，所有变量都是相应方法中的局部变量。
同样方便的是，在代码的主要部分周围使用了try except pass，它将忽略发生的任何错误。其中一个错误是您在几个方法中访问data，这些方法既不是全局变量也不是之前在方法中分配的。
删除try except pass以进行调试，并报告发生的情况。
