Python Web Scraping - Iterate to the next page of data form

I am trying to scrape from data from the following website for a mini project but was stuck mid way. Some help on this will be well appreciated! Apologies for not being able to post image. (would need more reputation :[)

Using the GET method on the link, I am able to obtain data from the first page.

There should be in total 339 counts of entry, where each page contains 19 entry

Please advise the best way to get all the links for the data I need. Many thanks in advance.
