    response = requests.get(url)

    if response.status_code == 200:
        return response.content
    else:
        print(f"Error fetching data. Status code: {response.status_code}")
        return None

3. 解析响应

def parse_html(html_content):
    soup = BeautifulSoup(html_content, 'html.parser')
    rank_items = soup.find_all('div', class_='placeholder one-img-plc')

    data = []
    for rank_item in rank_items:
        rank_num = rank_item.select_one('.rank-num').text
        title = rank_item.select_one('.plc-title').text
        url = rank_item.select_one('a')['href']

        data.append({
            'Rank': rank_num,
            'Title': title,
            'URL': url
        })

    return data

4.输出文件

    df = pd.DataFrame(data)
    df.to_excel('ranking_data.xlsx', index=False)
    print("Excel file created successfully.")
