Your main problem is that you are calling add_note when you bind it. You
don't want to do that. It will get called when the event (button press)
happens. Most (or hopefully) all of the remedy is:
1. rename text1 to self.text1
2. change "command = self.add_note(text1)" to
"command = self.add_note"
3. change "def add_note(self, text1):" to
4. delete "print text1"
5. chane "text_file.write(text1)" to
I think I got everything.
