Implement Baidu keyword ranking query using python

This article mainly introduces python to implement Baidu keyword ranking query. For more information, see a simple python function to query Baidu keyword ranking. The following are some introductions:
1. Random UA
2. The operation is simple and convenient. you can directly use getRank (keyword, domain name ).
3. encoding conversion. There should be no problem with coding.
4. rich results. Not only rankings, but also the title, URL, snapshot time of the search results, which meets SEO requirements
5. it is convenient to use software or use it on your own.

The function is implemented in a single thread, and the speed is slow. you can refer to modifying it as needed.

The code is as follows:

# Coding = UTF-8

Import requests
Import BeautifulSoup
Import re
Import random

Def decodeAnyWord (w ):
Try:
W. decode ('utf-8 ')
Except t:
W = w. decode ('gb2312 ')
Else:
W = w. decode ('utf-8 ')
Return w

Def createURL (checkWord): # create baidu URL with search words
CheckWord = checkWord. strip ()
CheckWord = checkWord. replace ('', '+'). replace ('\ n ','')
BaiduURL = 'http: // www.baidu.com/s? Wd = % s & rn = 100 '% checkWord
Return baiduURL

Def getContent (baiduURL): # get the content of the serp
