Is there a way to reference backspace in python with pynput?

Hi everyone I want to know if there is any way to reference backspace for my project, I want to do if the person presses 'a' then it deletes it and types 'ree' can someone pls help me with this?

Code:

COMBINATIONS = [
    {keyboard.KeyCode(char='a')}
]

current = set()

def execute():
    keyboard = Controller()
    if keyboard.on_press('a'):
        *insert code here*
    keyboard.type('ree')

def on_press(key):
    if any([key in COMBO for COMBO in COMBINATIONS]):
        current.add(key)
        if any(all(k in current for k in COMBO) for COMBO in COMBINATIONS):
            execute()


def on_release(key):
    if any([key in COMBO for COMBO in COMBINATIONS]):
        current.remove(key)

To overwrite a letter, you can send the '\b' which will move the cursor backwards one letter. Subsequent letters will then write over it.

from pynput.keyboard import Listener, Controller
from pynput import keyboard

key_ctrl = Controller()

def on_press(key):
    if key == keyboard.Key.esc:
        return False
    elif key == keyboard.KeyCode.from_char('a'):
        key_ctrl.type('\bree')

with Listener(on_press=on_press) as listener:
    listener.join()
