Use requests and BeautifulSoup crawling rookie tutorial code image and save it as markdown format

Open-book exam or design patterns, I want to prepare a little more information, then wrote a reptile crawling codes and images, there is cleverly format for further processing, eventually become a markdown format

import requests 
from bs4 import BeautifulSoup

First, get the rookie tutorial - html page of this factory model, the object into soup

r = requests.get("https://www.runoob.com/design-pattern/factory-pattern.html")
#获取反馈信息 200为正常
r.status_code
r.encoding = "utf-8"
soup=BeautifulSoup(r.text,'lxml')
print(soup.prettify())

Observe that by crawling links are required at the beginning of '/ design', so using startsWith () filter, to obtain a list of url

html_list=[]
for a in soup.find_all('a'):
    if(a['href'].startswith('/design')):
        print(a['href'])
        html_list.append(a['href'])

Write a crawling function of each page, the first markdown language in a comment, the comment with three slashes, convenient format.

+def fonepage(add):
    baseurl="https://www.runoob.com"
    url=baseurl+add
    r = requests.get(url)
    #获取反馈信息 200为正常
    r.status_code
    r.encoding = "utf-8"
    soup=BeautifulSoup(r.text,'lxml')
    lis=soup.find_all(attrs={'class':'example'})
    print('///## '+add)
    img=soup.find_all('img')
    print('///![]('+baseurl+img[0]['src']+')')
    print('///```')
    for son in lis:
        for a in son.find_all('span'):
            print(a.string,end=' ')
    print('\n')
    print('///```')

Then you can crawl by page

for i in range(2,len(html_list)):
    fonepage(html_list[i])

Finally, processing, utilization IDEA format, followed by notepad delete all '///' string, it is converted to a markdown format.

The results are as follows: https://www.cnblogs.com/Tony100K/p/11741212.html
