无法将 Tkinter 连接到 Sql 数据库 (Pyrhon)

如何解决无法将 Tkinter 连接到 Sql 数据库 (Pyrhon)

我正在一个项目中使用 Selenium(Python) 抓取亚马逊产品详细信息。我尝试使用 Tkinter for Gui 和 sqlite3 来存储数据。但是我在插入函数中遇到错误。而且我无法将 Tkinter 输出连接到数据库。如果我将 'prod_name1.get()' 和 'priceis1.get()' 分别更改为 'url_txt.get()' 和 'priceis_txt.get()'，我不再收到错误，但数据库为空只有当我使用输入框并使用“添加产品”按钮添加值时，它才会被填充。 代码如下：

amaz=Tk()
amaz.title("Amazon Sel")

con=sqlite3.connect('products.db')
curr=con.cursor()

curr.execute("CREATE TABLE IF NOT EXISTS Amaz(Id INTEGER PRIMARY KEY,Product TEXT,PriceFrom REAL,PriceIs REAL)")
con.commit()

def amazon():
    options=Options()
    
    path="C:/Users/xyz/PycharmProjects/pythonProject/Amaz/amaz.xlsx"
    workbk=openpyxl.load_workbook(path)
    sheet=workbk.active

    sheet.cell(row=1,column=1).value = "Product"
    sheet.cell(row=1,column=2).value = "Price"

    curr.execute("SELECT * FROM Amaz")
    all=curr.fetchall()
