from bs4 import BeautifulSoup

#getting all the contents of a url
url = 'https://en.wikipedia.org/wiki/Category:Free software'
content = requests.get(url).content
soup = BeautifulSoup(content,'lxml')

#showing the category-pages Summary
catPageSummaryTag = soup.find(id='mw-pages')
catPageSummary = catPageSummaryTag.find('p')
print(catPageSummary.text)

#showing the category-pages only
catPageSummaryTag = soup.find(id='mw-pages')
tag = soup.find(id='mw-pages')
links = tag.findAll('a')

#getting the category pages
catpages = soup.find(id='mw-pages')
whatlinksherelist = catpages.find_all('li')
things_to_write = []
for titles in whatlinksherelist:
  things_to_write.append(titles.find('a').get('title'))
  WAIT_TIME = 15
  print(titles.text)
  time.sleep(WAIT_TIME)  
#writing the category pages as a output file
with open('001-catPages.csv', 'a') as csvfile:
  writer = csv.writer(csvfile,delimiter="\n")
  writer.writerow(things_to_write)

将此添加到您的programe:-

#showing the category-pages only
catPageSummaryTag = soup.find(id='mw-pages')
tag = soup.find(id='mw-pages')
links = tag.findAll('a')
catpages = soup.find(id='mw-pages')
whatlinksherelist = catpages.find_all('li')
things_to_write = []
count = 0  #mentioned to count till 100
for titles in whatlinksherelist:
    if count<=100:
        things_to_write.append(titles.find('a').get('title'))
        count+=1
        print(titles.text)

#writing the category pages as a output file
with open('001-catPages.csv', 'a') as csvfile:
  writer = csv.writer(csvfile,delimiter="\n")
  writer.writerow(things_to_write)
