The Benefit and Risks for Scraping Based on Python

Abstract

As society's demand for the web has become greater, web crawler technology has been introduced and widely applied in various applications. Web crawling technology has a very controversial nature, with many people loving to use it, but many resisting. This study will discuss the definition of web crawling technology and analyze the reason why it is popular but also resisted by the public, and demonstrate the detail approach to implement web crawlers on Python. This leads to the conclusion that web crawling is a web technology that can save time and labor and can be applied to data investigation. The reason for its popularity is that it saves time and can automatically visit the desired web pages and retrieve data from them. However, it is resisted for many reasons, one of which is that it can cause damage to the interests of others, because web crawlers can collect paid data by special means. Python is the best language for running web crawlers because Python is the programming language that most resembles human language.
