Abstract

Python provides many toolkits for web data crawling and data analysis. Python – based BeautifulSoup can quickly and efficiently crawl Web data, Pandas tools can easily and flexibly clean and analyze data, Calling the Python Matplotlib toolkit can easily visualize the data analysis results. Based on Python functional standard library, Powerful third-party library requests, BeautifulSoup and regular expressions, Complete the reading of movie information data in file film.csv by programming; Clean and organize the read data; By using the Bar function to program the output of the weekly average box office of the film (the weekly average box office refers to the total average of all the weekly box offices involved in the city), Y axis represents box office revenue, Unit 10,000 yuan; X axis represents the film name.

By matplotlib the graphic library to visualize the data results and analyze them, the relevant conclusions are drawn. This paper lays a foundation for cultivating students’ data processing ability and visual analysis ability.
