title: Initializing Radio Buttons Tkinter
body: <p>I am trying to create a selection menu for questions with four options. I am instantiating four radio buttons, one for each choice. For some reason when the form shows up, the last three are already selected. When you click on one, only that button is selected, and there others become deselected. I would like it so the original version of the form has none of them selected.</p>
  
  <pre><code>            self.radio_button_frame = Frame(self)
              self.radio_button_frame.grid(row=1, column=1, rowspan=4)
              self.correct_label = Label(self, text="Correct: " + str(self.health_regain), width=25, justify=RIGHT)
              self.correct_label.grid(row=0, column=3)
              #space the image so it takes up 4 rows
              self.hydra_label.grid_forget()
              self.hydra_label.grid(row=0, column=0, rowspan=6)
  
              #get the question
              self.question = self.question_base.get_question()
              self.answer = 0
  
              #get rid of the begin button
              self.begin_button.grid_forget()
  
              #create radio buttons for each question choice
              self.description_label.config(text=self.question.question)
