Python Tkinter 按钮删除
Python Tkinter Button delete
我正在为自己制定一个财务计划，一整天都停留在这一点上，我尝试了很多对我不起作用的解决方案，所以我决定寻求帮助。
编辑：
我将程序与数据库连接起来，在这部分我试图“分期付款”——检查我是否支付了那个月的项目。我提取了这个问题所需的代码行并重命名了大多数变量，这样至少对你们来说可以理解一点，因为我是初学者并且我在空闲时间为自己编写程序对于错误感到抱歉。
痛点：
如果从列表中选择的付款是在最后一期付款（例如 4/4）我想制作功能并将其绑定到同一个按钮“选择付款”，这将完全销毁带有付款名称标签的按钮。我设法从数据库中删除了它，但按钮不会消失，直到程序重新启动，因为它不会被创建，因为它不再在数据库中，但我想在最后一次付款完成后立即删除它。解释这个问题对我来说真的很复杂，因为我的英语不是很好。我发布了我的原始程序的视频，以便你们了解我想要完成的事情。

btn = tk.Button(root, text="test", command=click)

那部分不再需要帮助，我只是设法用字典来完成。
这是第一部分，我将按钮 ID 作为值加入按钮文本作为键
for opis in self.lista_opisa_rata:
function = lambda x=opis: self.get_description(x)
rata_button = Button(self.onr_top, text=opis, width=10, command=function)
rata_button.grid(row=row, column=column, padx=5, pady=5)
self.dict_for_buttons[opis] = rata_button
这是第二部分，我通过将标签描述名称与按钮名称匹配并从字典中提取 ID 以按 ID 删除按钮来删除按钮。
def pay_selected(self):
p_description = self.onr_oznacena_rata_txt.cget("text")
num_of_installments = self.onr_broj_rata_txt.cget("text").split("/")
if int(num_of_installments[0]) + 1 >= int(num_of_installments[1]):
c.execute('DELETE FROM OTPLATA_NA_RATE WHERE Opis = ?',(p_description,))
conn.commit()
btn_to_del = self.dict_for_buttons[p_description]
btn_to_del.destroy()
self.dict_for_buttons.pop(p_description)
