以下是使用Python爬取当当网图书畅销榜的代码示例：

import requests
from bs4 import BeautifulSoup

# 发送请求获取网页内容
url = "https://book.douban.com/top250"
response = requests.get(url)
html_content = response.text

# 使用BeautifulSoup解析网页内容
soup = BeautifulSoup(html_content, "html.parser")

# 找到图书列表
book_list = soup.find_all("div", class_="pl2")

# 遍历图书列表并提取信息
for book in book_list:
    # 提取图书标题
    title = book.find("a").text.strip()
    
    # 提取图书作者和出版信息
    author_info = book.find("p", class_="pl").text.strip().split("/")
    author = author_info[0].strip()
    publisher = author_info[-3].strip()
    
    # 提取图书评分
    rating = book.find("span", class_="rating_nums").text.strip()
    
    # 打印图书信息
    print("标题：", title)
    print("作者：", author)
    print("出版社：", publisher)
    print("评分：", rating)
    print("--")
