How to parse article number from hyperlink?

Question

Python

I have the following hyperlink with the article number at the end of the url:

<a href="https://example.com/?p=5144" rel="bookmark"> example </a>

I am creating a telegram bot that compares the number of the last article with the one that was published, and if the number is higher, then the bot sends a notification about a new article.

How to extract article number from url? I use Python and beautifulsoup.
Thanks in advance.

Split

url = 'https://example.com/?p=5144'
page = url.split('?p=')[-1]

replacement

url = 'https://example.com/?p=5144'
page = url.replace('https://example.com/?p=', '')

Regex

import re
url = 'https://example.com/?p=5144'
page = re.search(r'\?p=(\d+)', url).group(1)
