 [Tkinter] TKINTER quiz using sqlite3 database
#41
Capture responses, and save to a file.
add to ChoiceMade function

I have to move on, we have between 15,000 and 19,000 visitors each day, not everyone posts,
but it's still tough keeping up. Only about a dozen of us to answer all.

I have added a student info class, store the DataEntry.py script in same directory as quiz.py script.
This isn't quite how I think it should be, I'll work on it when I have time, also, the information
isn't saved anywhere yet. I'll incorporate that into the file that stores quiz results (again as I find time).
So you will be getting this piece meal
** NOTE ** There are changes to quiz.py to load new class.
DataEntry.py:

      self.parent.title('Student Information')
      self.entry_widgets = self.create_form()

   def get_entries(self, entry_widgets):
      content = []
      for element in entry_widgets:
         field = element[0]
         content.append(element[1].get())
      return content

   def create_form(self):

         ent_entry = tk.Entry(ent_frame, relief=tk.SUNKEN)

Okay, thanks again and again for all your help I'm wouldn't have been able to do this without you. When you send the newest changes could you again include how you did it, so I can learn to do it myself?
