pagination for non standarded pages

[buran]

soup.find('ul', {'class': 'pagination'}) will return single element and you cannot iterate over it
no tested, but something like

pagination = soup.find('ul', {'class': 'pagination'})
pages = pagination.find_all('li')
num_pages = int(pages[-2].text)
print(num_pages)

if you inspect the ul element you will notice there are 4 types of li items (without class attribute, class=empty, class=next, class=is-active). you can play with custom function that will return just li items without class.
