Question

通过将变量username1和password1添加到数据库中，尝试创建一个显示新屏幕以注册新收银员的函数，但不断获取

sqlite3.InterfaceError: Error binding parameter 0 - probably unsupported type.

谁能告诉我我要去哪里错了？非常感谢

def register():
    username = StringVar()
    password = StringVar()
    global Home
    root.withdraw()
    Home = Toplevel()
    Home.title("The Belgium Fries Guys")
    width = 500
    height = 400
    screen_width = root.winfo_screenwidth()
    screen_height = root.winfo_screenheight()
    x = (screen_width/2) - (width/2)
    y = (screen_height/2) - (height/2)
    root.resizable(0, 0)
    Home.geometry("%dx%d+%d+%d" % (width, height, x, y))
    lbl_home = Label(Home, text="Register New Cashier:", font=('Arial', 18)).grid()
    btn_back = Button(Home, text='Back', command=Back).grid(pady=20, columnspan=3)

    lbl_username1 = Label(Home, text = "Username:", font=('arial', 14), bd=15)
    lbl_username1.grid(row=3, sticky="e")
    lbl_password1 = Label(Home, text = "Password:", font=('arial', 14), bd=15)
    lbl_password1.grid(row=4, sticky="e")
    lbl_text = Label(Home)
    username1 = Entry(Home, textvariable=username, font=(14))
    username1.grid(row=3, column=1)
    password1 = Entry(Home, textvariable=password, show="*", font=(14))
    password1.grid(row=4, column=1)

    global conn, cursor
    conn = sqlite3.connect("cashier.db")
    cursor = conn.cursor()
    cursor.execute("CREATE TABLE IF NOT EXISTS `member` (mem_id INTEGER NOT NULL PRIMARY KEY  AUTOINCREMENT, username TEXT, password TEXT)")  
    cursor.execute("insert into member(username, password) values (?, ?)",(username1, password1))

    btn_register = Button(Form, text="Register", width=25, command=register)
    btn_register.grid(pady=25, row=4, columnspan=3)
    btn_register.bind('<Return>', register)
