What is a python web crawler?

A Python Web Crawler is a program written in Python that automatically navigates the web, retrieves information from websites, and often stores or processes this data for further use. Web crawlers, also known as spiders or bots, are commonly used for indexing website content, data mining, or collecting data from multiple web pages. Python is a popular language for creating web crawlers due to its robust libraries such as BeautifulSoup, Scrapy, and Requests, which make it easier to handle HTTP requests, parse HTML, and manage large-scale crawling. Properly designed crawlers respect website rules by following robots.txt files and rate limits to avoid overloading servers. They are widely used in search engines, price comparison sites, and research projects.
