问题描述

来自 bs4 的代码导入请求 import BeautifulSoup

LIMIT = 50
URL = f"https://au.indeed.com/jobs?q=Python&limit={LIMIT}&radius=50"

def extract_indeed_pages():
  result = requests.get(URL)
  soup = BeautifulSoup(result.text, "html.parser")
  pagination = soup.find("div", {"class":"pagination"})
  links = pagination.find_all("a")
  pages = []
  for link in links[:-1]:
      pages.append(int(link.string))
  max_page = pages[-1]
  return max_page



def extract_indeed_jobs(last_page):
  jobs = []
  # for page in range(last_page):
  result = requests.get(f"{URL}&start={0*LIMIT}")
  soup = BeautifulSoup(result.text, "html.parser")
  results = soup.find_all("div", {"class": "jobsearch-SerpJobCard"})
  for result in results:
      title = result.find("div", {"class": "title"}).find("a")["title"]
      company = result.find("span", {"class": "company"})
      if company is None:
        print(company.find("a").string)
      else:
        print(company.string)
  return jobs

我不想看到任何东西，只想看到公司名称。我试图解决这个问题，但是我无法解决这个问题。我很感激你的建议

解决方案

不需要打印 None 字符串，你可以像这样简单地输入

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

或者出于任何原因你想要它而不是让它

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