How do i use a While/For loop to create classes?? (Python/PyQt) -

-

i have created code create multiple classes different class names (i.e. question1, question2 etc.)

import sys pyqt4 import qtcore, qtgui  class starttest(qtgui.qmainwindow):     def __init__(self, parent=none):         super(starttest, self).__init__(parent)         self.central_widget = qtgui.qstackedwidget()         self.setcentralwidget(self.central_widget)         question1 = question1(self)         self.central_widget.addwidget(question1)         self.central_widget.setcurrentwidget(question1)         question1.proceed.clicked.connect(self.question2)     def question2(self):         question2 = question2(self)         self.central_widget.addwidget(question2)         self.central_widget.setcurrentwidget(question2) = 0 while i<2:     class question+i(qtgui.qwidget):         def __init__(self, parent=none):             super(question+i, self).__init__(parent)             question = qtgui.qlabel('what 5+5?')             self.proceed = qtgui.qpushbutton("proceed")             self.answer = qtgui.qlineedit(self)             layout = qtgui.qformlayout()             layout.addrow(question, self.answer)             layout2 = qtgui.qvboxlayout()             layout2.addlayout(layout)             layout2.addwidget(self.proceed)             self.setlayout(layout2)             print('question'+i)  if __name__ == '__main__':     user = ''     app = qtgui.qapplication([])     window = starttest()     window.showfullscreen()     app.exec_()

however when write:

i = 0 while i<2:     class question+i(qtgui.qwidget):

i obtain syntax error on question+i part error, undertandable. how overcome whilst still creating multiple classes different class names???

see this related question answers on how set class names dynamically.

you need implement factory method. might this:

def factory(num) :     baseclass = qtgui.qwidget     class newclass(baseclass): pass     newclass.__name__ = "factory_%s%d" % (baseclass.__name__,  num)     return newclass

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
