请帮我写个Python爬虫代码
以下是一个简单的使用requests和BeautifulSoup库来爬取网页标题的Python示例代码。首先确保你已经安装了这两个库，可使用pip install requests beautifulsoup4进行安装。
import requestsfrom bs4 import BeautifulSoup
def get_webpage_title(url): try: # 发送HTTP GET请求 response = requests.get(url) # 检查请求是否成功 response.raise_for_status() soup = BeautifulSoup(response.content, 'html.parser') # 获取网页标题 title = soup.title.string return title except requests.RequestException as e: print(f"请求出现错误: {e}") return None
if __name__ == "__main__": target_url = "https://www.example.com" # 替换为你要爬取的网址 page_title = get_webpage_title(target_url) if page_title: print(f"网页标题是: {page_title}")
