How can I add pagination to the Hacker News Reader template?

To add pagination to the Hacker News Reader, you can modify the home_route() function in routes.py and update the home.html template. Here's an example of how to implement basic pagination:

In routes.py: ```python @app.route("/", defaults={'page': 1}) @app.route("/page/") def home_route(page): stories_per_page = 10 top_stories_url = "https://hacker-news.firebaseio.com/v0/topstories.json" all_top_stories = requests.get(top_stories_url).json()

   start = (page - 1) * stories_per_page
   end = start + stories_per_page
   page_stories = all_top_stories[start:end]

   stories = []
   for story_id in page_stories:
       story_url = f"https://hacker-news.firebaseio.com/v0/item/{story_id}.json"
       story = requests.get(story_url).json()
       stories.append(story)

   total_pages = len(all_top_stories) // stories_per_page + 1

   return render_template("home.html", stories=stories, page=page, total_pages=total_pages)

```

Then, update home.html to include pagination links: ```html

{% if page > 1 %} Previous {% endif %} {% for p in range(1, total_pages + 1) %} {% if p == page %} {{ p }} {% else %} {{ p }} {% endif %} {% endfor %} {% if page < total_pages %} Next {% endif %}

```

This implementation adds page numbers and previous/next links to navigate through the stories.
