Get total_page when parsing?

Question

Python

def get_total_pages(html):
    soup = BeautifulSoup(html, 'lxml')
    pages = soup.find('div', class_='pagination-pages').find_all('a', class_='pagination-page')[-1].get('href')
    total_pages = pages.split('=')[1].split('&')[0]
    return int(total_pages)

In the first case, everything is clear, we can simply find the last one from the array and refer to the number in the reference.
But what if we don't have a last button ?

In general, there is an option how to bypass enclose your loop in try except if you fail, just put break and that's it! and it stops parsing what is not there, this is such a simple but working option
