How do I bypass captcha while Web Scraping using Python?
s A typical captcha consists of a distorted test which aputer program cannot interpret but a human can (hopefully) still read. You can use OCR (Optical Character Recognition) libraries in Python to bypass captchas . Popular open source OCR tools are Tesseract GOCR and Ocrad. Pillow Python Package Pillow is a fork of the Python Image library having useful functions for manipulating . It must be used with the function named form_parser() that is defined in the previous script for getting information about the registration form. This script will save the CAPTCHA s. For this purpose we are going to use open source Tesseract OCR engine. It can be installed with the help of followingmand u2212 pip install pytesseract code Example Here we will extend the above Python script which loaded the CAPTCHA by using Pillow Python Package as follows u2212 import pytesseract code img = get_captcha(html) code ('') code gray = ('L') code ('') code bw = (lambda x if x < 1 else 255 '1') code ('') code The above Python script will read the CAPTCHA in black and white mode which would be clear and easy to pass to tesseract as follows u2212 (bw) code s
