    conn = sqlite3.connect('books.sqlite')
    c = conn.cursor()

    count = c.execute('SELECT count(*) FROM library')
    countf = c.fetchall()
    num = countf[0][0]

    totle = c.execute('SELECT * FROM library')
    totlef = c.fetchall()

    rows = None
    for rows in range(0, num):
         rows

    for values in totlef:
         values[0]
         values[1]
         values[2]
         values[3]
         values[4]
         values[5]
         values[6]
         values[7]
         tree.insert('', rows,values=(values[0], values[1], values[2], values[3], values[4], values[5], values[6], values[7]))

    conn.commit()
    conn.close()


    tree.pack(side=TOP)
