Today, the editor will share with you the relevant knowledge points about how to write the code for python crawling Douban movie TOP250 data. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

Before executing the program, create a database "pachong" in MySQL.

Import pymysqlimport requestsimport re# acquires resources and downloads def resp (listURL): # Connect database conn = pymysql.connect (host = '127.0.0.1, port = 3306, user =' root', password ='*', # database password enter database = 'pachong' according to your actual password Charset = 'utf8') # create database cursor cursor = conn.cursor () # create list t_movieTOP250 (execute sql statement) cursor.execute (' create table t_movieTOP250 (id INT PRIMARY KEY auto_increment NOT NULL) MovieName VARCHAR (20) NOT NULL Pictrue_address VARCHAR)') try: # crawl data for urlPath in listURL: # get web page source code response = requests.get (urlPath) html = response.text # regular expression namePat = raster = "(. *?)"
