How to Handle Google CAPTCHAs in Selenium with Python
Challenge:
When scraping websites, you may encounter Google CAPTCHAs that hinder your automation efforts. Can Selenium with Python assist in bypassing these CAPTCHAs?
Understanding Selenium and CAPTCHA
Selenium automates browsers for testing and web application automation. However, CAPTCHAs are designed to distinguish humans from bots. Using Selenium to bypass CAPTCHAs is generally not recommended due to detection risks.
Generic Solutions
Despite the detection risk, there are some generic measures to avoid being detected as a bot:
- Use a non-default viewport size.
- Rotate the User Agent for each request.
- Introduce delays beyond the default wait time to simulate human behavior.
Specific Cases
While bypassing CAPTCHAs is not ideal, it may be possible in certain cases. Here are some discussions that address specific scenarios:
