from urllib.request import urlopenfrom bs4 import BeautifulSoupimport reimport csvhtml = urlopen('http://www.app12345.com/?area=tw&store=Apple%20Store')bs0bj = BeautifulSoup (html)def GPname(): GPnameList = bs0bj.find_all('dd',{'class':re.compile('ddappname')}) str = ’’ for name in GPnameList:str += name.get_text()str += ’n’print(name.get_text()) return strdef GPcompany(): GPcompanyname = bs0bj.find_all('dd',{'style':re.compile('color')}) str = ’’ for cpa in GPcompanyname:str += cpa.get_text()str += ’n’print(cpa.get_text()) return strwith open(’0217.tsv’,’w’,newline=’’,encoding=’utf-8’) as f: f.write(GPname()) f.write(GPcompany())f.close()

写csv文件简单点 你的结构数据要成这样 [['1. 東森新聞雲','新聞'],['2. 創世黎明(Dawn of world)','遊戲']]

from urllib import urlopenfrom bs4 import BeautifulSoupimport reimport csvhtml = urlopen('http://www.app12345.com/?area=tw&store=Apple%20Store')bs0bj = BeautifulSoup (html)GPnameList = [name.get_text() for name in bs0bj.find_all('dd',{'class':re.compile('ddappname')})]GPcompanyname = [cpa.get_text() for cpa in bs0bj.find_all('dd',{'style':re.compile('color')})]data = ’n’.join([’,’.join(d) for d in zip(GPnameList, GPcompanyname)])with open(’C:/Users/sa/Desktop/0217.csv’,’wb’) as f: f.write(data.encode(’utf-8’))
