Entering numbers from the numpad using pynput (or any other library)

I am trying to enter Alt-codes of symbols using the pynput library (Imitation of pressing "Alt" and entering code on the numpad)

from pynput.keyboard import Key, Controller

keyb = Controller()

def alt_codes(start, finish):  
    for i in range(start, finish + 1):
        keyb.press(Key.alt)
        time.sleep(0.01)
        for j in str(i):
            keyb.press(j)
            time.sleep(0.01)
            keyb.release(j)
            time.sleep(0.01)
        keyb.release(Key.alt)
        time.sleep(0.01)
        keyb.press(Key.space)
        time.sleep(0.01)
        keyb.release(Key.space)

But if I just try to simulate pressing the numbers 0 to 9, it doesn't work, because it simulates pressing the keys that are above the letters, and to enter the Alt code, you need to simulate the numbers from the Numpad. How can I simulate pressing numbers on a numpad? UPD: You can use any other library if needed.

For specifically targeting the Numpad keys you can use their Virtual-Key Codes

You can find the whole list here https://cherrytree.at/misc/vk.htm

Now for the Code to Use the Virtual Key Codes

keyb.press(key=KeyCode.from_vk(96)) #Number tells which numpad key to press, 96 means 0

instead of

keyb.press(j)

You can change the start to finish instead of 0 to 9 to 96 to 105. In this way, you can press the specific key subsequently Or you can define a mapping for it like this:

get_keycode = {
    0: 96,
    1: 97,
    2: 98,
    3: 99,
    4: 100,
    5: 101,
    6: 102,
    7: 103,
    8: 104,
    9: 105
} 

Now your final code would be (I tried writing Euro Sign ALT-Code is 0128):

from pynput.keyboard import Key, Controller, KeyCode
import time

keyb = Controller()
    
get_keycode = {
    0: 96,
    1: 97,
    2: 98,
    3: 99,
    4: 100,
    5: 101,
    6: 102,
    7: 103,
    8: 104,
    9: 105
}

def get_key(key):
    return KeyCode.from_vk(get_keycode[int(key)])
    
euro_sign = "0128"
keyb.press(Key.alt)
time.sleep(0.01)
for j in euro_sign:
    keyb.press(get_key(j))
    time.sleep(0.01)
    keyb.release(get_key(j))
    time.sleep(0.01)
keyb.release(Key.alt)
time.sleep(0.01)
keyb.press(Key.space)
time.sleep(0.01)
keyb.release(Key.space)

Hope this helps!
