I have created a program in Python which simulates the growth rates of crops. The user is able to chose between the crop is wheat or potatoes I am trying to create a GUI using PYQT. The problem I am having is that when I try and load the program the program is not recognizing the other screen layouts. The main function should be setting up the screen layouts

  • "the program is not recognizing the other screen layouts" I don't understand what that means and what the problem is. Could you create a minimal example showing the error and describe what are the other layouts and how to recognize them? – NoDataDumpNoContribution Aug 30 '17 at 07:40
  • The comment is coming back NameError: global name 'WheatWindow' is not defined so the program is not connecting to the different screen when I use the if __name__ == main: call – da axe man Aug 30 '17 at 08:36
  • Please see: https://stackoverflow.com/questions/423379/using-global-variables-in-a-function-other-than-the-one-that-created-them That should help you with WheatWindow although global variables might not be a good style. – NoDataDumpNoContribution Aug 30 '17 at 09:15
  • WheatWindow is the name of the screen I am trying to set up in PYQT, the program will connect all of the screens without the if__name__ ==_"main"__ should I run the main function independently – da axe man Aug 30 '17 at 11:33
  • Thank you for the tip on global variables I used a global counter and saved it – da axe man Aug 30 '17 at 17:53
