我在使用标签语法更新输出文本并将其替换为 customtkinter gui 时遇到问题。当我单击该按钮时，它没有被新按钮替换。下面是我的代码。

from PIL import Image
customtkinter.set_appearance_mode("dark")
customtkinter.set_default_color_theme("dark-blue")
root = customtkinter.CTk()
root.title("Movie Recoomendation")
root.geometry("700x700")

如果我单击“前 5 名向我推荐一部电影”按钮，应该会出现我添加的电影列表，然后如果我尝试单击“前 3 名向我推荐一部电影”按钮，则应将其替换为前 3 名电影列表.
每当单击 pick 按钮时，您都会创建新的标签集，因此新的标签集可能不可见，因为它们被推到窗口底部之外。
您可以为这些标签创建一个框架，并且需要在显示新标签之前销毁以前创建的标签
