【摘要】 目前，我国正在加大环境保护的力度。如何充分利用互联网上的已有的海量数据为低碳环保事业做出贡献，是我们不可推缺的责任。为快速爬取网络上的信息，网络爬虫应运而生。通过使用网络爬虫技术,能在短时内提取有价值的信息数据。得到有价值的数据后，根据数据的形式进行整理，运用HTML、CSS、JavaScript、Flask框架、Echarts、WordCloud等技术对数据进行可视化展现。将数据进行完整地分析，有利于更好地利用数据解决实际问题。本文将对基于Python的聚焦式网络爬虫设计与实现以及分析天气数据并可视化地展现作出简介。更多还原

【Abstract】 At present, our country is stepping up the environmental protection efforts. How to make full use of the existing huge amount of data on the Internet to contribute to the cause of low-carbon environmental protection to be our compelling obligation. In order to crawl quickly the information on the network, the network crawler was born. By using web crawler technology, valuable information can be extracted in a short time. After the valuable data is obtained, it is organized according to the form of the data, and the data is visualized by using HTML、CSS、JavaScript, Flask framework,Echarts, WordCloud and other technologies. A complete analysis on the data is conducive to better use of data to solve practical problems. This article will introduce the design and implementation of focused Web crawlers based on Python and the analysis and visualization of weather data.更多还原
