  soup=BeautifulSoup(result.text,"html.parser")

  for result in results:
    title=result.find("h2",{"class":"title"}).find("a")["title"]

  print(title)  // get Title

  return jobs

  results = soup.find_all('div', {"class" : 'jobsearch-SerpJobCard'})
  for result in results :

   company = result.find("span", {"class":"company"})

   // get company
   if company.find("a") is not None :
     print(company.find("a").string)
   else :

  return jobs
