This article mainly introduces python and the code used to query google Keyword rankings by shell. For more information about the code, see the company of my wife recently. Our company is engaged in seo, and there are a lot of keywords and websites to query. It is so distressing to watch our elders repeat the search work so hard. So I spent some time using python

Shell Curl and Python requests Stumbled upon a distinction between the curl and the requests library. The scene is like this – This uses curl to initiate a POST request: Curl-v-x POST http://api.xx.com/api/yy.php--data ' params={"sign": "XXXX", "data": [{"UID": "Remark": "Just4test"}] }' The backend interface service can parse the params parameters and respond to the results normally. But when I switch to

Bpython is a good Python interpreter interface. This article will take you to understand bpython. Interested friends can refer to Python as a very practical and popular interpreted programming language, one of its advantages is that it can use its interactive shell for exploratory programming. You can try to enter some code and get feedback from the interpreter i

First, execute the shell using Python's built-in commands module Commands encapsulates Python's Os.popen (), uses the shell command string as its parameter, returns the result data of the command, and the state of the command execution; The order is now obsolete and replaced by subprocess; # coding=utf-8 "Created on November 22, 2013 @author: crazyant.net" Import commandsimport pprint def cmd_exe (cmd_ S
