您好!对于使用Python进行豆瓣电影爬虫的课设,您可以按照以下步骤进行:
1. 导入需要的库:
```
import requests
from bs4 import BeautifulSoup
import csv
```
2. 发送HTTP请求获取网页内容:
```
url = "https://movie.douban.com/top250"
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.182 Safari/537.36"}
response = requests.get(url, headers=headers)
```
3. 使用BeautifulSoup解析网页内容:
```
soup = BeautifulSoup(response.text, "html.parser")
```
4. 提取电影信息:
```
movie_list = soup.find_all("div", class_="item")
for movie in movie_list:
title = movie.find("span", class_="title").text
rating = movie.find("span", class_="rating_num").text
# 提取其他信息...
```
5. 将提取的数据保存到CSV文件中:
```
with open("movies.csv", "w", newline="", encoding="utf-8-sig") as file:
writer = csv.writer(file)
writer.writerow(["电影名称", "评分"]) # 写入表头
for movie in movie_list:
title = movie.find("span", class_="title").text
rating = movie.find("span", class_="rating_num").text
writer.writerow([title, rating])
```
以上是一个简单的豆瓣电影爬虫的基本流程,您可以根据需要进行进一步的数据提取和处理。希望对您有所帮助!若有其他问题,请随时提问。
