"What’s the best way to start crawling with Python for web scraping?"
Hey folks! 👋 Newbie here trying to get into crawling with python. I’ve played around with requests and BeautifulSoup, but I feel like I’m missing something.
Any tips on libraries or frameworks to make it easier? Scrapy seems popular, but is it overkill for small projects? Also, how do you handle those pesky dynamic sites that load content with JS?
And uh… how do I not get blocked immediately? 😅
Thanks in advance!

Hey! For crawling with python, start simple with requests + BeautifulSoup if you're just scraping static pages. Scrapy is awesome but yeah, might be overkill for small stuff.
For JS-heavy sites, check out Selenium or Playwright—they let you control a real browser. And to avoid blocks, rotate user-agents and use proxies (try free ones like ScraperAPI or Bright Data).
Big rookie mistake? Not respecting robots.txt and hammering a site too fast. Pace your requests!
Scrapy is actually pretty lightweight once you get the hang of it, and it handles a lot of the messy stuff for you (like retries, throttling).
But if you're just dipping your toes into crawling with python, maybe stick with requests + bs4 first. For dynamic content, Puppeteer (JS) is great, but if you're Python-only, Pyppeteer is a decent alternative.
Oh, and always—ALWAYS—add delays between requests. Sites hate getting bombarded.
lol yeah, getting blocked is the worst. For crawling with python, I’d say:
- Use `requests-html`—it’s like requests but with JS support (kinda).
- For proxies, check out free tiers on ProxyMesh or Luminati.
- And if you’re scraping a lot, cache your results so you don’t re-scrape the same pages.
Big gotcha? Forgetting to handle errors. Sites change all the time, so your script WILL break.
If you’re just starting with crawling with python, don’t overcomplicate it. BeautifulSoup + requests is fine for most things.
But for dynamic sites, Selenium is the go-to, even if it’s slow. For speed, try `httpx` with `asyncio`—it’s like requests but async.
And yeah, getting blocked… rotate headers, use proxies, and maybe even mimic human behavior (random delays, mouse movements if using Selenium).
Wow, thanks everyone! This is super helpful. I didn’t even know about Playwright—gonna try that for the JS stuff.
Quick follow-up: How do you guys handle CAPTCHAs? I tried a few things but they’re a pain. Also, any favorite proxy providers for small projects?
(And yeah, I learned the hard way about hammering a site too fast. Oops.)
Scrapy isn’t overkill if you plan to scale later! It’s got built-in stuff for handling queues, retries, and even exporting data.
For JS, Playwright is my fav—way faster than Selenium. And for avoiding blocks, try adding `fake-useragent` to randomize your headers.
Pro tip: Start small. Don’t try to scrape Amazon on day one. 😅
Honestly, crawling with python is fun but messy. For dynamic content, I’d say go with Selenium or Playwright—they’re lifesavers.
And yeah, getting blocked sucks. Use `time.sleep()` between requests, and maybe even try Cloudflare-bypass tools if you’re hitting those walls.
Big mistake? Not checking if the site has an API first. Sometimes you don’t even need to scrape!
