How do I bind the enter key to a function in Tkinter?

Pressing a key and handling some operation with the key is an event that can be triggered through a button. We can bind the key event using the Binding method in a tkinter application.

Whenever the key will be triggered, it will call a handler that will raise the specific operation for the key event.

If we want to trigger the Enter key with the bind function, we will use the bind('<Key>', Handler) method. For Enter Key, we use bind('<Return>', Handler) function.

Example

#Import the tkinter library
from tkinter import *

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

#Set the geometry
win.geometry("650x250")

def handler(e):
   label= Label(win, text= "You Pressed Enter")
   label.pack()

#Create a Label
Label(win, text= "Press Enter on the Keyboard", font= ('Helvetica bold', 14)).pack(pady=20)

#Bind the Enter Key to Call an event
win.bind('<Return>',handler)

win.mainloop()

Output

It will display the following window −

Now, if we will press "Enter" on the keyboard, it will display “You Pressed Enter”.
