調用類中方法的方法的問題

Question

爲什麼這些方法不能像我期望的那樣工作？我可以在 這個方法後打印一行，但是，其他的功能似乎都不起作用。

我想

1. 指定目錄
2. 迭代在文件中使用的glob
3. 指定文件處理程序目錄
4. 找到的每個文件使用的方法彙總，然後調用一系列相互呼叫的其他方法。
5. 排序和解析文件
6. 打印排序和解析的結果。

代碼：

#This utility attempts to parse the output text files generated by dcp_inspect 
#for faster inspection and when attending to multiple DCP inspections. 
#dcp_inspect_parse runs on Python3.x

我覺得奇怪，我沒有你的變量開始self.，這意味着你沒有任何類成員，所有的變量都在各自的方法本地。

同樣方便您在代碼的主要部分周圍使用try except pass，它將忽略發生的任何錯誤。其中一個錯誤是您可以通過幾種方法訪問data，這些方法既不是全局變量也不是以前在該方法中分配的。

刪除try except pass用於調試目的並報告發生了什麼。
