Web Scraping in Python by BeautifulSoup, Scrapy & Selenium

Web 抓取是通过计算机程序从 Internet 自动收集数据的做法，而无需使用 API 和 Web 浏览器。还有一些其他术语，包括屏幕抓取、网络收集、网络爬行、数据挖掘都包含在网络抓取中。
与人类从访问网站的网络浏览器复制粘贴重要数据不同，网络抓取可以使该过程自动化。网页抓取现在对数据科学家来说非常重要。数据科学家分析从各种媒体收集的数据。现在，大部分数据来自不同的网站。由于 Python 编程在收集数据方面非常流行，因此许多数据科学家使用 Python 编程来解决这个问题。
如果我们分析谷歌的业务，我们会看到谷歌最初是作为一个搜索引擎开始的。他们的搜索引擎最初是使用 Python 编程构建的。即使在一项研究中，来自 twitter、facebook、blog 的不同类型的消息也被抓取来构建一个用于构建预测模型的数据集。因此，知道如何使用 Python 抓取 Web 数据是一项必须掌握的重要技能。
不要浪费您宝贵的时间，
我创建了尽可能简短而有用的课程。在短时间内，您可以学习有关使用 Python 进行网页抓取的所有重要主题和技术。我教了两种不同的方法来使用 Python 废弃网站。因此，您可以使用相同的技术来删除其他类似的网页。

Description
Web scraping is the practice of gathering data from the internet automatically by a computer program without using API and web browser. There are some other terms including screen scraping, web harvesting, web crawling, data mining all are including in web scraping.
Instead of copy-pasting important data by a human from a web browser visiting a website, web scraping can automate the process. Web scraping is now very important for a data scientist. A data scientist analysis data collected from various media. Now, most of the data come from different websites. As Python programming is very popular for harvesting data, many data scientist use Python programming to solve that.
If we analyze the business of Google, we will see Google initially started as a search engine. Their search engine was initially built using Python programming. Even in a study, different types of message from twitter, facebook, blogs were scraped to construct a data set which was used to build a predictive model. So knowing how to use Python to scrape web data is an important skill one has to know.
Don’t waste your precious time
I created this course as short and useful as possible. Within a short period of time, you can learn all the important topics and techniques about web scraping using Python. I taught two different way to scrap websites using Python. So using the same technique you can apply to scrap other similar webpages.
