我正在尝试对我的数据进行排序，类似于此处的排序示例：http: //www.blog.pythonlibrary.org/2011/01/04/wxpython-wx-listctrl-tips-and-tricks/

但是由于某种原因，当我的数据出现在表格中时，事情就变得无处不在。例如，计算机名称与所有者不匹配。起初我虽然没有正确创建字典。但后来我尝试打印它，字典看起来非常好。因此，错误必须与 list_ctrl 一致。你知道我的错误在哪里吗？

看起来您复制并粘贴了我的代码，但更改了关键部分。您需要将init中的 for 循环更改为如下所示：

for key, data in items:
    print "%s: %s - %s" % (key, data[0], data[1])
    print
    self.list_ctrl.InsertStringItem(index, data[0])
    self.list_ctrl.SetStringItem(index, 1, data[1])
    self.list_ctrl.SetItemData(index, key)
    index += 1

我在示例中留下的“self.index”设置为零，但我从未在该循环中使用它。相反，我创建了一个名为index的局部变量并使用它。我已通过删除self.index位来修复我的文章，因为在该特定示例中不需要它。

在您的代码中，您增加索引，但在所有 self.list_ctrl.*() 方法中使用 self.index。

我一直在从 Mike Driscoll 关于 mixin 的帖子中学习。 http://www.blog.pythonlibrary.org/2011/01/04/wxpython-wx-listctrl-tips-and-tricks/ 制作任何文本逗号分隔符文件。
这是更好的方法：

import sys
import wx
import  wx.lib.mixins.listctrl  as  listmix

info = csv.reader(open('yourFile.txt', 'rb'),delimiter=',')
sortedlist = sorted(info, key=operator.itemgetter(1), reverse=True)

length = 0
textDB = []
for row in sortedlist: 
    textDB.append([length,row[0],row[1]])
    length = length + 1
dict_info = {}
rows = 0

for item in textDB:
    dict_info[item[rows]] = (item[rows + 1], item[rows + 2])
