The issue lies in how you’re selecting the elements in your scrape_data function. In the line start_date, end_date = (e.get_text(strip=True) for e in soup.select('span.extra strong')[-2:]), you’re expecting two values to be returned, but instead, it’s returning a generator with only one value. To fix this issue, you should iterate over the elements and extract their text separately. Here is an updated version of your scrape_data function: def scrape_data(url): response = requests.
