How to insert a temporary text in a tkinter Entry widget?

To insert a temporary text in a tkinter Entry widget, we will bind the <FocusIn> event with the Entry widget and call a user-defined function to delete the text inside the Entry widget.

Steps −

Import the tkinter library and create an instance of tkinter frame.
Set the size of the frame using geometry method.
Create a user-defined method "temp_text()" to capture the <FocusIn> event and delete the temporary text inside the Entry widget.
Create an Entry widget inside the Root window and set its properties such as background color, width, and border width.
Use the insert() method of the Entry widget to insert a string from the starting location "0". This is the temporary text which will disappear when the Entry widget is in clicked.
Bind the <FocusIn> event with the Entry widget and call the temp_text() method.
Finally, run the mainloop of the application window.

Example

# Import the required library
from tkinter import *

# Create an instance of tkinter frame
win = Tk()

# Define geometry of the window
win.geometry("700x250")

def temp_text(e):
   textbox.delete(0,"end")

textbox = Entry(win, bg="white", width=50, borderwidth=2)
textbox.insert(0, "This is Temporary Text...")
textbox.pack(pady=20)

textbox.bind("<FocusIn>", temp_text)

win.mainloop()
