Different Column values not displayed in PYGTK TreeView

Вопрос

I executed this program : 

#!/usr/bin/env python

import gtk

class CellRenderer:
    def __init__(self):
        window = gtk.Window()
        window.set_default_size(200,200)

        liststore = gtk.ListStore(str, str)
        liststore.append(["Fedora","http://fedoraproject.org"])
        liststore.append(["Slackware","http://www.slackware.com"])
        liststore.append(["Sidux","http://sidux.com"])

        treeview = gtk.TreeView(liststore)
        column_text = gtk.TreeViewColumn("Distributions")
        column_sample= gtk.TreeViewColumn("Links")
        treeview.append_column(column_text)
        treeview.append_column(column_sample)

        cellrenderer_text = gtk.CellRendererText()
        column_text.pack_start(cellrenderer_text,False)
        column_text.add_attribute(cellrenderer_text,"text",0)

        cellrenderer_sample = gtk.CellRendererText()
        column_sample.pack_start(cellrenderer_sample, False)
        column_sample.add_attribute(cellrenderer_sample,"text", 0)

        window.connect("destroy", lambda q : gtk.main_quit())
        window.add(treeview)
        window.show_all()

CellRenderer()
gtk.main()

The resultant window I obtained is this :

As you may have noticed, the lists appended to liststore had links in the second index.Why weren't any of those links displayed in the second column?

Решение

You are referring to same index at 

column_sample.add_attribute(cellrenderer_sample,"text", 0)

change it to 

column_sample.add_attribute(cellrenderer_sample,"text", 1)

Full file.
