Python Program

import tkinter as tk

# Create the main window
window = tk.Tk()
window.title("PythonExamples.org")
window.geometry("300x200")

label = tk.Label(window, text="Enter your favorite color")
label.pack()

# Create an Entry widget with default text
default_text = "White"
entry = tk.Entry(window)
entry.insert(0, default_text)
entry.pack()

# Run the application
window.mainloop()
