callback_query在嵌入式键盘中多次工作

如何解决callback_query在嵌入式键盘中多次工作

下面是代码。 当我的代码第一次运行时，它像一个超级按钮一样工作，但是当我再次输入URL并单击任何按钮时，它显示2张图片（其中1张来自上一个结果），第三次显示3张图片。图片（2张图片来自之前的结果），依此类推。 因此，当我再次输入URL时，它应该只能运行一次。 使用以下屏幕截图，您可以更好地了解我的问题。

When codes run for the first time

When it runs again with the same URL

When it runs for 3rd time with different URL

因此，要解决此问题，最好的选择是什么
