how to insert into labeltext in python

To insert text into a `Label` widget in Python, you can use the `config` method of the widget. Here's an example:

import tkinter as tk

# Create a window
window = tk.Tk()

# Create a Label widget
label = tk.Label(window, text="Hello, World!")
label.pack()

# Change the text of the Label
label.config(text="New text")

# Run the window
window.mainloop()

In this example, we create a `Label` widget with the text "Hello, World!", and add it to a window using the `pack` method. Then, we use the `config` method to change the text of the `Label` to "New text". Finally, we run the window using the `mainloop` method.
