How can I handle errors in web scraping?

Handling errors in web scraping involves implementing try-except blocks, logging errors, and retrying requests.

What types of errors should I be aware of?

Common errors include HTTP errors, timeouts, and parsing errors. Each requires a different handling strategy.

Can you give me an example of error handling in Python?

Sure! You can use the requests library with a try-except block to catch exceptions like this:

import requests

try:
    response = requests.get('http://example.com')
    response.raise_for_status()  # Raises an HTTPError for bad responses
except requests.exceptions.RequestException as e:
    print(f'Error occurred: {e}')

What should I do if the website blocks my requests?

If you're blocked, consider using rotating proxies, adjusting your request frequency, or using headless browsers.
