循环数组停止增加索引(Orig:Message小部件文本随机不刷新)

在tkinter中,我创建了一个GUI,它可以读取数据并以某种表格的形式实时显示。这些小部件是按程序生成的,并以预定义的名称存储在一个集合中,稍后会基于该名称调用它们,并修改其内容。 然而,当数据被读取并放入窗口小部件时,一些看似随机的单元格是空的。当我说随机时,它实际上是相当一致的(col2、row2和col5到7,row2到3),但是当我以某种方式更改报告文件时,新值可能会出现,也可能不会出现(这确实是非常随机的)。

import tkinter as tk

class MainApplication(tk.Frame):

    global SkillWidgets
    SkillWidgets = {}


    def __init__(self, parent, *args, **kwargs):
        tk.Frame.__init__(self, parent, *args, **kwargs)       
        self.parent = parent
        self.create_stuff()
        self.refresh()


    def create_stuff(self):        
        screen_width = tkGUI.winfo_screenwidth()
        screen_height = tkGUI.winfo_screenheight()
        iSW = screen_width/1000
        iSH = screen_height/1000

        tkFrSkills = tk.Frame(tkGUI)
        tkFrSkills.place(x=(100*iSW)+20, y=20+(50*iSH), bordermode=tk.INSIDE, height=screen_height/2-(100+50*iSH), width=screen_width)

        for iRow in range(1,4):

                tkMsg = tk.Message(tkFrSkills, text="", font=("Arial", 36), relief = tk.GROOVE, bd = 2, width = 100)
                tkMsg.place (x=((iCol-1)*100*iSW), y=(75*iRow*iSH)-(75*iSH), bordermode=tk.INSIDE, width = 100*iSW, height = 75*iSH)
                SkillWidgets[(iRow,iCol)] = tkMsg



    def refresh(self):
        fSkills = open("report.txt")
        sSkContents = fSkills.read()
        fSkills.close()

        SkLines = sSkContents.split("\n")
        del(SkLines[len(SkLines)-1])

        iSkRow = 0
        for sSkLine in SkLines:  
            if "X" in sSkLine:
                iSkRow = 1

            if iSkRow > 0:
                SkItems = sSkLine.split(";")
                SkItems[1], SkItems[2], SkItems[3], SkItems[4] = SkItems[2], SkItems[4], SkItems[1], SkItems[3]
                SkItems[2] = str(int(SkItems[3])-int(SkItems[1]))              
                del(SkItems[0])                                      
             ***print(SkLines[iSkRow])

                for sSkItem in SkItems:

                    iSkCol = SkItems.index(sSkItem)+1
                ****print("Row=",iSkRow,"Col=",iSkCol,"sSkItem=",sSkItem)
               *****print("Row=",iSkRow,"Col=",iSkCol,"widget text =", SkillWidgets[(iSkRow,iSkCol)].cget("text"))
                    SkillWidgets[(iSkRow,iSkCol)].config(text = sSkItem)
                ****print("Row=",iSkRow,"Col=",iSkCol,"sSkItem=",sSkItem)
               *****print("Row=",iSkRow,"Col=",iSkCol,"widget text =", SkillWidgets[(iSkRow,iSkCol)].cget("text"))
                    print("----------")


        self.after(1000,self.refresh)

if __name__ == "__main__":

    MainApplication(tkGUI).pack(side="top", fill="both", expand=True)
    tkGUI.mainloop()

编辑: 我忘了提到我试图打印我输入的值(代码已调整-我用一些星号突出显示了这些地方

***此打印正确地给出了相关行,但由于某种原因,它在循环中运行了两次,给出了

X;6;4;0;0;32;3;0.8125
Y;2;1;0;0;0;0;0
Z;5;1;0;0;0;0;0

****这个打印正确地给出了我想输入到小部件的值

*****这张照片正成为问题的根源: a) 如果输入值为“1”,循环根本不会经过2:2,但只给出了2:1两次,第一次打印将小部件的值显示为“1 b) 如果输入值为“2”或更大,则按预期工作-循环按预期经过2:1、2:2、2:3

Row= 2 Col= 1 sSkItem= 1
Row= 2 Col= 1 widget text = 
Row= 2 Col= 1 sSkItem= 1
Row= 2 Col= 1 widget text = 1
----------
Row= 2 Col= 1 sSkItem= 1
Row= 2 Col= 1 widget text = 1
Row= 2 Col= 1 sSkItem= 1
Row= 2 Col= 1 widget text = 1
----------

Row= 2 Col= 1 sSkItem= 1
Row= 2 Col= 1 widget text = 
Row= 2 Col= 1 sSkItem= 1
Row= 2 Col= 1 widget text = 1
----------
Row= 2 Col= 2 sSkItem= 3
Row= 2 Col= 2 widget text = 
Row= 2 Col= 2 sSkItem= 3
Row= 2 Col= 2 widget text = 3
----------

c) 在这两种情况下,循环都不适用于第2行;3至5至7列

编辑2:

编辑3: 我似乎正在找到原因……此时,对于第2行和第3行,它只是在第5次迭代中停止增加索引(索引为4的项未加载,而是再次加载索引为3的项)

            for sSkItem in SkItems:
                print(SkItems)
                print("item3: ", SkItems[3])
                print("item4: ", SkItems[4])
                print("item5: ", SkItems[5])
                print("item6: ", SkItems[6])
                iSkCol = SkItems.index(sSkItem)
                print("index", iSkCol)
                print("Row=",iSkRow,"Col=",iSkCol,"sSkItem=",sSkItem)
                print("Row=",iSkRow,"Col=",iSkCol,"widget text =", SkillWidgets[(iSkRow,iSkCol)].cget("text"))
                SkillWidgets[(iSkRow,(iSkCol))].config(text = sSkItem)
                print("Row=",iSkRow,"Col=",iSkCol,"sSkItem=",sSkItem)
                print("Row=",iSkRow,"Col=",iSkCol,"widget text =", SkillWidgets[(iSkRow,iSkCol)].cget("text"))

结果打印输出如下:
