Tkinter Entry widget is used to display a single line text. Using tkinter Entry widget, we can set its value or content by triggering a button. It has mainly two types of operation: insert and delete.
Using the Tkinter Button widget, we will set the content of the Entry widget.
Example
#Import the required libraries
from tkinter import *
#Create an instance of tkinter frame
win= Tk()
#Define a function to change the value
def change_text(txt):
text.delete(0,END)
text.insert(0,txt)
#Set the geometry of frame
win.geometry("600x250")
#Create an Entry Widget
text= Entry(win)
text.pack()
#Create a button to change/set the content
btn= Button(win,text="Set", command=lambda:change_text("My New Text"))
btn.pack(pady=20)
win.mainloop()Output
Running the code will display a window containing a button that will set the value or text of the entry widget.
Now click on the “Set” button to set a new value for Entry Widget.
