from ex import dbconnect
data = [['Male', 0, 'cheap', 'Low', 'Bus'], ['Male', 1, 'cheap', 'Medium', 'Bus'], ['Female', 1, 'cheap', 'Medium', 'Train'], ['Female', 0, 'cheap', 'Low', 'Bus'], ['Male', 1, 'cheap', 'Medium', 'Bus'], ['Male', 0, 'standard', 'Medium', 'Train'], ['Female', 1, 'standard', 'Medium', 'Train'], ['Female', 1, 'expensive', 'High', 'Car'], ['Male', 2, 'expensive', 'Medium', 'Car'], ['Female', 2, 'expensive', 'High', 'Car']]
data1 = ['Gender', 'car ownership', 'Travel Cost', 'Income Level', 'Transportation mode']

#this class i got helped with it

class Wizard(QtGui.QWizard):

   def __init__(self):
       super(Wizard, self).__init__()
       datas = []
       for l in range(len(data1) - 2):
           y = []
           for row in data:
               x = row[l]
               if not x in y:
                   y.append(x)
           datas.append(y)
       titles = data1
       self.setStyleSheet(('font:50 10pt "MS Shell Dlg 2";'))
       self.setWindowTitle("Recommender System")

       self.groups = []
       for title, options in zip(titles, datas):
           page, group = Wizard.create_page(title, options)
           self.addPage(page)
           self.groups.append(group)

       self.button(QtGui.QWizard.FinishButton).clicked.connect(

               self._results.append(button.text())

   @QtCore.pyqtSlot()

       hlay = QtGui.QHBoxLayout(page)
       for option in options:
           radiobutton = QtGui.QRadioButton(text=str(option))
           group.addButton(radiobutton)
           hlay.addWidget(radiobutton)
       return page, group

#this passed from the class like the r = Wizard.results()

   page.setTitle("Conclusion!")

   list1 = QtGui.QListView()

       list1.setModel(model)
   layout = QtGui.QVBoxLayout()
   layout.addWidget(list1)
   page.setLayout(layout)
   return page

def run1():

   global data, data1

   if app is None:
       app = QtGui.QApplication([])
   wizard = Wizard()
   wizard.addpage(finalpage(wizard.results())
   sys.exit(app.exec_())
run1()

I don't know where and when to call the final page

If you want to get information from the QWizard or QWizardPage before you change pages, you must override the initializePage method.

from PyQt4 import QtCore, QtGui

data = [
    ["Male", 0, "cheap", "Low", "Bus"],
    ["Male", 1, "cheap", "Medium", "Bus"],
    ["Female", 1, "cheap", "Medium", "Train"],
    ["Female", 0, "cheap", "Low", "Bus"],
    ["Male", 1, "cheap", "Medium", "Bus"],
    ["Male", 0, "standard", "Medium", "Train"],
    ["Female", 1, "standard", "Medium", "Train"],
    ["Female", 1, "expensive", "High", "Car"],
    ["Male", 2, "expensive", "Medium", "Car"],
    ["Female", 2, "expensive", "High", "Car"],
]
data1 = [
    "Gender",
    "car ownership",
    "Travel Cost",
    "Income Level",
    "Transportation mode",
]


class Wizard(QtGui.QWizard):
    def __init__(self):
        super(Wizard, self).__init__()
        datas = []
        for l in range(len(data1) - 2):
            y = []
            for row in data:
                x = row[l]
                if not x in y:
                    y.append(x)
            datas.append(y)
        titles = data1
        self.setStyleSheet(('font:50 10pt "MS Shell Dlg 2";'))
        self.setWindowTitle("Recommender System")

        self.groups = []
        for title, options in zip(titles, datas):
            page, group = Wizard.create_page(title, options)
            self.addPage(page)
            self.groups.append(group)

        final_page = FinalPage()
        self.addPage(final_page)

    @property
    def results(self):
        return self.get_options()

    def get_options(self):
        results = []
        for group in self.groups:
            button = group.checkedButton()
            if button is not None:
                results.append(button.text())
        return results

    @staticmethod
    def create_page(title, options):
        page = QtGui.QWizardPage()
        group = QtGui.QButtonGroup(page)
        page.setTitle(title)
        page.setSubTitle("Please choose one of these state.")
        hlay = QtGui.QHBoxLayout(page)
        for option in options:
            radiobutton = QtGui.QRadioButton(text=str(option))
            group.addButton(radiobutton)
            hlay.addWidget(radiobutton)
        return page, group


class FinalPage(QtGui.QWizardPage):
    def __init__(self, parent=None):
        super(FinalPage, self).__init__(parent)
        self.setTitle("Conclusion!")

        self._model = QtGui.QStandardItemModel(self)

        listview = QtGui.QListView()
        listview.setModel(self._model)
        label = QtGui.QLabel("Based on these Ruls")
        label.setStyleSheet(('font:50 10pt "MS Shell Dlg 2";'))

        lay = QtGui.QVBoxLayout(self)
        lay.addWidget(listview)
        lay.addWidget(label)

    def setResults(self, r):
        for m in r:
            item = QtGui.QStandardItem(str(m))
            self._model.appendRow(item)

    def initializePage(self):
        self.setResults(self.wizard().results)


if __name__ == "__main__":
    import sys

    app = QtGui.QApplication(sys.argv)
    w = Wizard()
    w.show()
    sys.exit(app.exec_())
