## What it is
A Chinese-language tutorial repository teaching Python web scraping from zero, covering requests, data extraction, JS reverse engineering, Selenium, Tesseract OCR, MongoDB, and the Scrapy framework. It combines written lessons with practical example crawlers for sites like Douban and Baidu.

## Use cases
- learn python web scraping from scratch
- understand how to reverse engineer javascript for crawlers
- scrape websites with selenium
- recognize captcha images with tesseract ocr
- store scraped data in mongodb
- learn the scrapy framework
- extract  and regex data from web pages

## When to choose
- you are a beginner wanting a structured Chinese-language crawler tutorial
- you want hands-on examples covering requests, selenium, scrapy, and OCR in one place

## When to avoid
- you need an actively maintained production scraping library
- you need English-language documentation
- you need a tool rather than learning material

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: web-scraping, ocr, parser, developer-tools
- domain: crawlers, tutorials, developer-tools
- platform: python, cross-platform
- tags: python-crawler, js-reverse-engineering, selenium, scrapy, mongodb, tesseract-ocr, chinese-language, natural-language-processing
