- import urllib.request
- import urllib.parse
- import re
- from bs4 import BeautifulSoup
- def main():

- keyword = urllib.parse.urlencode({"word":keyword})
- response = urllib.request.urlopen("http://baike.baidu.com/search/word?%s" % keyword)
- html = response.read()
- soup = BeautifulSoup(html, "html.parser")
- for each in soup.find_all(href=re.compile("view")):
- content = ''.join([each.text])
- url2 = ''.join(["http://baike.baidu.com", each["href"]])
- response2 = urllib.request.urlopen(url2)
- html2 = response2.read()
- soup2 = BeautifulSoup(html2, "html.parser")
- if soup2.h2:
- content = ''.join([content, soup2.h2.text])
- content = ''.join([content, " -> ", url2])
- print(content)
- if __name__ == "__main__":
