How to bind the other "Enter" on the keyboard in python tkinter?

Question

I am writing a tkinter app in python 3.12.0 (on windows) and I want to bind the other "Enter" (Which is in Num-Lock part of keyboard) that when I press it, send my message. I am using a Text Widget and I need the main Enter for break line. I hove solved my problem with beneath code and it works on my system; But I'm looking for a better solution and I don't know if this function works on other systems or even if it works on a different OS.

def foo(event=None):
if not (event.keysym=="Return" and event.state in [
    262144, # Caps Lock Off, Num Lock Off, Scroll Lock Off
    262146, # Caps Lock On , Num Lock Off, Scroll Lock Off
    262152, # Caps Lock Off, Num Lock On , Scroll Lock Off
    262154, # Caps Lock On , Num Lock On , Scroll Lock Off
    262176, # Caps Lock Off, Num Lock Off, Scroll Lock On
    262178, # Caps Lock On , Num Lock Off, Scroll Lock On
    262184, # Caps Lock Off, Num Lock On , Scroll Lock On
    262186, # Caps Lock On , Num Lock On , Scroll Lock On
    ]):
    return
# do the code

My problem is already solved. I just want to know is there a better way to bind the other "Enter"?

Edit: As I told in the first place: I want to use only the second Enter button and I think I couldn't get my point across.

Here is my code:

import tkinter as tk
def foo(event=None):
    print(event) 
    print(event.state)
    # to bind only to other Enter, but not the main Enter:
    if event!=None and (not (event.keysym=="Return" and event.state in [
        262144, # Caps Lock Off, Num Lock Off, Scroll Lock Off
        262146, # Caps Lock On , Num Lock Off, Scroll Lock Off
        262152, # Caps Lock Off, Num Lock On , Scroll Lock Off
        262154, # Caps Lock On , Num Lock On , Scroll Lock Off
        262176, # Caps Lock Off, Num Lock Off, Scroll Lock On
        262178, # Caps Lock On , Num Lock Off, Scroll Lock On
        262184, # Caps Lock Off, Num Lock On , Scroll Lock On
        262186, # Caps Lock On , Num Lock On , Scroll Lock On
        ])):
        return
    print("Yey!")

root = tk.Tk()
text = tk.Text(root, width=60, height=8)
text.bind('<Key>', foo)
text.pack()
tk.Button(root, text='Send', command=foo).pack()
root.mainloop()

Answer 1

Try this:

def foo(event=None):
    if event and (not (event.keysym == "Return" and (event.state & 262144))):
        return
    print("Yey!")

However, if you press the keypad Enter along with additional keys such as shift, ctrl, alt or others, printing will still occur. If you want printing to happen when you only press keypad Enter and don't press any additional keys (other than various locks), try this code:

def foo(event=None):
    if event and (not (event.keysym == "Return" and (event.state & 524245) == 262144)):
        return
    print("Yey!")

Just recently I've found a third option: Try to use the bind on Extended-Return:

def foo(event=None):
    print("Yey!")


root = tk.Tk()
text = tk.Text(root, width=60, height=8)
text.bind('<Extended-Return>', foo)
…

Should give the same result as the first example.

Answer 2

See tkinter Key names, for a list of the relevant bindings. As you can see KP-Enter is the key on the keypad, and Return is the one on the main keyboard.

Answer 3

Binding to <KP_Enter> should work. Here is an example:

import tkinter as tk

def send_message(event):
    print("message sent!")
    return "break"

root = tk.Tk()

text = tk.Text(root)
text.pack(fill="both", expand=True)
text.bind("<KP_Enter>", send_message)

tk.mainloop()
