python 类可以包含删除 itslef 的方法吗？

问：

我正在编写一个用于数据操作的 tkinter 类。我想找到一种方法通过单击按钮来删除对象，就像退出窗口的 X 按钮一样。
这是我的界面的样子：

主窗口是一个包含 matplotlib 绘图和常规控件的类。
右边的三个“小部件”中的每一个都是一个类的对象，该类包含来自加载的 csv 文件的数据帧和一些特定的控件，例如 x 轴和 y 轴变量的选择。

我希望 X 按钮使小部件及其包含的所有内容消失，并使绘图从主对象中消失（我认为这部分必须手动完成）。
下面是 Widget 类的初始化和控件的定义：

class Data_Widget():
    """ This Class creates the main window with the curve plot and general buttons like open files, Clear all, Plot all.
    
    Arguments:
    -master: the parent window, automatically the PlotWindow class
    -data: data loaded into the widget self.data used to plot the curve
    -filepath: the filepath of the loaded data
    -color: color of the curve
    
    methods:
    -create_widget_controls : create the controls (buttons...)
    -set_widget_color : set the color of the associated curve
    -set_x_var and set_y_var : set the x and y var of the plotted curve
    -master_plot : gives the order of plotting the curve to the master class (PlotWindow) (method plot_widget)
    -master_clear_plot : gives the order of clearing the plot to the master class (PlotWindow) (method clear_widget_plots)
    -delete_widget : delete the widget
    -create_exportload_popup : export the data contained in the widget as CSV file.
                Used where widget has been created by selecting data from another widget with PlotWindow multiple selection method

    def __init__(self, master, data = pd.DataFrame(), filepath='Nothing loaded', x_var=None, y_var= None, color="blue"):

        self.widget_frame.destroy()

目前，该功能仅使帧消失，但它只是可视化的，所有数据仍然存在。
我写了一个应该用于从外部删除对象，但我无法弄清楚如何使用它，从内部删除对象。destroy_widgetdef__del__(self)
