Python網路爬蟲王者-Selenium

ISBN：9789863794127

相信時致今日，沒有人可以否認網路上的資料近乎無窮無近，只端看你要如何使用它。

《Python網路爬蟲王者-Selenium》完全是目的導向的工具書。目標讀者是有心瞭解網路爬蟲技術的人。書中從基本的網頁結構開始講解，尊定讀者後績學習的基礎。再藉由一小段一小段的程式練習範例，讓讀者自然而然地熟習網頁元素定位的技巧。在看完第4章之後，我已經能完成工作上需要的網路爬蟲任務了。

書本的中後半段，是把重心轉向網頁程式的自動化測試。這原本就是Selenium當初出被開發出來的用途。只是Selenium實在太好用，所以僅是拿來當成網路爬蟲的工具，就已經是值回票值了。網頁程式自動化測試目前在台灣IT圈，應該不算普遍被採用的技術（人工測試比較多），對於網頁程式工程師來說，多瞭解絕對是好事，或許能有派上用場的一天。

如前文所述，網路上的資料什麼都有、什麼都不奇怪，藉由網路爬蟲的協助，取得有意義的資料來做分析、應用，用以優化企業流程，在未來是各行各業都可能探用的作法。從事後端工程師職務的從業人員，都應視為基礎能力的一環。

I believe that, even today, no one can deny that the amount of information on the Internet is almost endless. It all depends on how you choose to use it.

**《Python Web Scraping King – Selenium》** is a very practical book with a clear goal. It is written for people who want to learn about web scraping. The book starts with the basic structure of web pages, building a good foundation for further learning. It then uses short programming exercises to help readers gradually become familiar with how to locate elements on a web page. After finishing Chapter 4, I was already able to complete the web scraping tasks I needed to do at work.

In the second half of the book, the focus shifts to **automated testing** for web applications. This was actually the original purpose for which **Selenium** was developed. However, Selenium is so useful that using it only as a **web scraping** tool is already worth the price of the book. Automated testing for web applications is probably not yet widely used in Taiwan's IT industry, where manual testing is still more common. For web developers, learning more about it is definitely a good thing. You never know when it might come in handy.

As mentioned earlier, the Internet contains almost every kind of information you can imagine. With the help of web scraping, we can collect meaningful data for analysis and practical applications, and use it to improve business processes. In the future, this could become a common approach in many different industries. For people working as backend engineers, web scraping should be considered one of the basic skills worth having.
