How to clear Tkinter Canvas using Python?

To clear a Tkinter canvas in Python, you can use the delete() method of the canvas widget. This method allows you to remove all items drawn on the canvas, effectively clearing it. Here's how you can do it:

import tkinter as tk
def clear_canvas():
    canvas.delete("all")
# Create a Tkinter window
root = tk.Tk()
root.title("Clear Canvas Example")
# Create a canvas
canvas = tk.Canvas(root, width=400, height=300, bg="white")
canvas.pack()
# Create some items on the canvas (for demonstration)
# Example: Draw a rectangle
canvas.create_rectangle(50, 50, 200, 150, fill="blue")
# Create a button to clear the canvas
clear_button = tk.Button(root, text="Clear Canvas", command=clear_canvas)
clear_button.pack()
# Run the Tkinter event loop
root.mainloop()

In this example:

We create a Tkinter window and a canvas widget.

We draw some items on the canvas (a rectangle in this case) for demonstration purposes.

We define a function clear_canvas() that uses the delete("all") method to remove all items from the canvas.

We create a button that calls the clear_canvas() function when clicked.

Finally, we start the Tkinter event loop to display the window and handle user interactions.

When you click the "Clear Canvas" button, it will remove all items drawn on the canvas, effectively clearing it.
