Ich versuche herauszufinden, wie man eine Zeile sowohl aus der Listbox als auch aus sqlite3 löscht. Ich habe eine 'delButton'-Funktion am unteren Rand. Muss ich die Zeile aus der Listbox und SQL löschen? Ich bin mir nicht sicher, was ich hier mache, was das Löschen betrifft, ich habe diese Funktion durch Kopieren und Einfügen aus verschiedenen Beispielen zusammengestellt.

from Tkinter import *
import sqlite3

class Hello():
    def __init__(self, master):

        frame=Frame(master, width=80, height=50)
        frame.pack()

        self.text = Label(frame, text="         ")
        self.text.pack()
        self.text.grid(row=0, sticky=W)
        self.text["text"] = "                  Address Book"

        self.lab = Label(frame, text="name")
        self.lab.pack(side=LEFT)
        self.lab.grid(row=1)

        self.nameField = Entry(frame, text = "name", width=30)
        self.nameField.insert(0, "Enter Name")
        self.nameField.pack()
        self.nameField.grid(row=1)
        self.nameField.bind("<FocusIn>", self.clearNameField)

        self.ageField = Entry(frame, text = "age", width=30)
        self.ageField.insert(0, "Enter Age")
        self.ageField.pack()
        self.ageField.grid(row=2)
        self.ageField.bind("<FocusIn>", self.clearAgeField)

        self.phoneField = Entry(frame, text = "phone", width=30)
        self.phoneField.insert(0, "Enter Phone #")
        self.phoneField.pack()
        self.phoneField.grid(row=3)
        self.phoneField.bind("<FocusIn>", self.clearPhoneField)

        self.fbField = Entry(frame, text = "fblink", width=30)
        self.fbField.insert(0, "Enter Facebook Link")
        self.fbField.pack()
        self.fbField.grid(row=4)
        self.fbField.bind("<FocusIn>", self.clearFbField)

        self.btn=Button(frame, text='Add', command=self.add_note)
        self.btn.pack()
        self.btn.grid(row=5, rowspan=1, sticky="w")

        self.showbtn = Button(frame, text='Update', command=self.show_notes)
        self.showbtn.pack()
        self.showbtn.grid(row=5, rowspan=1, sticky="")

        self.delbtn = Button(frame, text='Delete', command=self.del_notes)
        self.delbtn.pack()
        self.delbtn.grid(row=5, rowspan=1, sticky="e")


        self.content=Listbox(master, width=50)
        self.content.pack()

    def clearNameField(self, event):
        self.nameField.delete(0,END)

    def clearAgeField(self, event):
        self.ageField.delete(0,END)

    def clearPhoneField(self, event):
        self.phoneField.delete(0,END)

    def clearFbField(self, event):
        self.fbField.delete(0,END)


    def add_note(self):
        if self.nameField.get() == "":
            self.text["text"] = "Please type sumting"
        else:
            item = self.nameField.get()
            item2 = self.ageField.get()
            item3 = self.phoneField.get()
            item4 = self.fbField.get()
            self.nameField.delete(0, END)
            self.ageField.delete(0, END)
            self.phoneField.delete(0, END)
            self.fbField.delete(0, END)

            conn = sqlite3.connect('phonebook1.db')
            c = conn.cursor()
            conn.execute('''
        CREATE TABLE IF NOT EXISTS people(name TEXT primary key,
                       age TEXT, phone TEXT, fblink TEXT)''')
            c.execute("insert into people values (?, ?, ?, ?)", (item, item2, item3, item4))
            conn.commit()
            list=c.execute("SELECT * FROM people")
            conn.commit()

            for row in list:
                self.content.insert(END, row)
            c.close()


    def del_notes(self):
        conn = sqlite3.connect('phonebook1.db')
        c =conn.cursor()
        list=c.execute("SELECT * FROM people")
        conn.commit()
        for row in list:
            self.content.delete(END, row)
        c.close()

Hier ist der Fehler.
