Question

def __init__(self):         self.companys= set()         self.jobs=set()         self.filelist=[]         self.reall=[]     def GetFileList(self,dir):         for s in os.listdir(dir):             self.filelist.append(s)     def FileHandle(self):         while(self.filelist):             filename=self.filelist.pop()             soup=BeautifulSoup(open('resources/'+filename),'html.parser')             link_jobs=soup.find_all('span','title')             link_companys=soup.find_all('span','org summary')             if link_jobs:                 for i in range(len(link_jobs)):                     item=[link_jobs[i].string,link_companys[i].string,filename]                     self.reall.extend(item)                     从item=[link_jobs[i].string,link_companys[i].string,filename]开始提示                     list index out of range,但是感觉i是在范围内的啊？

Answer 1

link_jobs与link_companys包含元素数目不同？
