基于案例的Python课程教学研究——以网络爬虫和数据可视化教学内容为例

Teaching Research on Python Course Based on Case Method--Taking the Teaching Content of Web Crawler and Data Visualization as an Example

本文针对Python课程中网络爬虫及应用、数据可视与展示教学内容的教学难点,采用案例教学法来解释网络爬虫收集数据方法以及如何实现数据分析和数据可视化分析。该案例通过Python软件抓取拉勾网站上特定话题的内容以及其评论等相关信息,通过Python第三方库实现相关数据分析与可视化。从而帮助学生理解网络数据爬取、数据分析与可视化的主要流程,掌握大数据时代下分析问题、解决问题的新思路。

Aiming at the teaching difficulties of web crawler and its application and data visualization and display in Python course,this paper uses case teaching method to explain the data collection method of web crawler and how to realize data analysis and data visualization analysis.This case uses Python software to capture the content of specific topics and their comments and other relevant information on the pull website,and realizes the relevant data analysis and visualization through Python third-party libraries.In order to help students understand the main process of network data crawling,data analysis and visualization,master the new ideas of problem analysis and problem solving in the era of big data.
