我现在要用python3.4.3的shell来设计一个爬虫,网站是https://x.com/search?q=lululemon&src=typed_query,我想要抓取前100条内容的文本,内容包括文本内容、账号、ip地址。存储成一个csv格式

在Python 3.4.3环境下,你可以使用requests库获取网页内容,然后结合BeautifulSoup解析HTML,提取你需要的信息。这里是一个基本的步骤:
首先,安装必要的库,如果还没安装的话:
```bash
pip install requests beautifulsoup4 pandas
```
接下来,创建一个Python脚本,比如`web_crawler.py`:
```python
import requests
from bs4 import BeautifulSoup
import csv
# 定义目标URL和CSV文件路径
url = "https://x.com/search?q=lululemon&src=typed_query"
output_file = 'results.csv'
def get_content(url):
response = requests.get(url)
if response.status_code == 200:
return response.text
else:
print(f"Failed to fetch URL: {response.status_code}")
return None
def parse_html(html):
soup = BeautifulSoup(html, 'html.parser')
# 根据实际的HTML结构提取文本内容、账号和IP地址(假设它们有特定class或id)
content_elements = soup.find_all('div', class_='content')[:100]
account_elements = soup.find_all('span', class_='account')[:100]
ip_elements = soup.find_all('span', class_='ip')[:100]
data_list = [(element.text for element in content_elements),
(element.text for element in account_elements),
(element.text for element in ip_elements)]
return data_list
def save_to_csv(data_list, output_file):
with open(output_file, 'w', newline='', encoding='utf-8') as csvfile:
writer = csv.writer(csvfile)
writer.writerows(data_list)
if __name__ == "__main__":
html_content = get_content(url)
if html_content is not None:
extracted_data = parse_html(html_content)
save_to_csv(extracted_data, output_file)
print("Crawling and saving completed.")
else:
print("No data fetched.")
```
请注意,上述代码中,你需要根据实际的HTML结构替换`find_all`函数的参数。因为不同的网站结构可能会有所不同,你需要找到包含文本内容、账号和IP地址的具体标签。
运行这个脚本,它会抓取并保存前100条内容到CSV文件中。
