输出的时候显示一下是第几页的数据

好的，你可以将代码修改为以下形式：

import requests
from bs4 import BeautifulSoup
from pprint import pprint

for page in range(5):
    url = "https://movie.douban.com/subject/30391186/comments?start={}&limit=20&sort=new_score&status=P".format(page*20)
    headers = {
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3"
    }
    response = requests.get(url, headers=headers)
    soup = BeautifulSoup(response.text, "html.parser")
    comments = []
    for comment in soup.select(".comment-item"):
        content = comment.select_one(".comment-content").get_text().strip()
        author = comment.select_one(".comment-info a").get_text().strip()
        likes = comment.select_one(".votes").get_text().strip()
        time = comment.select_one(".comment-time").get_text().strip()
        location = comment.select_one(".comment-location").contents[-1].strip()
        comments.append({
            "content": content,
            "author": author,
            "likes": likes,
            "time": time,
            "location": location
        })
    print("第{}页的数据：".format(page+1))
    pprint(comments)

这段代码中，我们在循环中添加了一个print语句，用于显示当前是第几页的数据。我们使用了format方法来将页码转换为字符串，并使用print函数将其输出。
