What are some performance tips for web scraping with Python 3.10 and asyncio?
To improve performance in web scraping with Python 3.10 and asyncio, consider using asynchronous requests, optimizing your I/O operations, and managing concurrency effectively.
Can you explain how to use asynchronous requests?
Sure! You can use the aiohttp
library to make asynchronous HTTP requests. This allows your program to handle multiple requests simultaneously without blocking.
What about handling rate limits?
To handle rate limits, implement a delay between requests using asyncio.sleep()
, and check the response headers for any rate limit information.
Are there any libraries you recommend for parsing HTML?
Yes, I recommend using BeautifulSoup
or lxml
for parsing HTML. They work well with asyncio and can help you extract data efficiently.
