How to teach a bot to isolate numbers in a specific position of a message, and send a command to PM with this number?

Question

Python

I'm trying to make a bot for a text game, or rather a buyer's bot.
But I can't figure out how, in principle, to write a code for isolating numbers in a message in one chat, and sending a message with them in another. I've been sitting on this case for not so long, but it's very interesting how it can be implemented.

An example of a message in the original chat:
⚖........... puts up for auction (214422): 1*Leather tunic - 900 gold, you need to isolate exactly the number in brackets, for each such message they are different every time.

An example of the final in another chat:
Buy lot - 214422

Is this possible through any functions associated with variables?

Answer 1

import re

s = "выставляет на аукцион (214422): 1*Кожаная туника - 900 золота , " \
    "нужно вычленить именно число в скобках, у каждого такого сообщения они каждый раз разные."

lot_re = re.compile(r'\((?P<lot_id>\d+)\)')
result = lot_re.search(s).groupdict()
print(result)

{'lot_id': '214422'}

Answer 2

It is most convenient to isolate numbers with regular expressions https://docs.python.org/3/library/re.html
