How do I make $12.00 Original pizza default so that it is not a check button and is automatically charged in the message box?

I am having trouble.

# Pack the Buttons. self.ok_button.pack(side='left') self.quit_button.pack(side='left')

# Pack the frames. self.top_frame.pack() self.bottom_frame.pack() # Start the mainloop. tkinter.mainloop()

# Determine which Checkbuttons are selected and # build the message string accordingly and # add the price of toppings to the total. if self.cb_var0.get() == 1: self.message = self.message + 'Pizza ' total+=12.00 if self.cb_var1.get() == 1: self.message = self.message + 'Pepperoni ' total+=1.00 if self.cb_var2.get() == 1: self.message = self.message + 'Pineapple ' total+=0.50 if self.cb_var3.get() == 1: self.message = self.message + 'Anchovy ' total+=1.50 if self.cb_var4.get() == 1: self.message = self.message + 'Jalapeno ' total+=0.50 if self.cb_var5.get() == 1: self.message = self.message + 'Mushroom ' total+=0.50 #print total with two digits after the decimal self.message = self.message + "Total : $%.2f"%total
