Urllib.urlencode () Urllib and URLLIB2 are all related modules that accept URL requests, but provide different functionality. The two most notable differences are as follows: Urllib can only accept URLs and cannot create a request class instance with headers set. However, Urllib provides urlencode methods to get query string generation, while URLLIB2 does not. (This is the main reason Urllib and urllib2 often use together.) Coding work using Urllib'surlencode()function that will

access| Encapsulation | data | Database encapsulation as a DLL can bring many benefits, including only property rights protection, as well as efficiency and security performance improvements. The encapsulated DLL file in this example hides the actual path to the Access database. VB-generated DLLs encapsulate ASP code to connect to the database (Access). This article uses one of the simplest examples of connecting an Access database to illustrate how to encapsulate ASP code as a DLL file. We u

First, why the URL encodingThe request format for URL with parameters is (for example): Http://www.baidu.com/s?k1=v1k2=v2When the request data is a dictionary, the database = {k1:v1, k2:v2}, and the parameter contains Chinese or? , = and other special symbols, by URL encoding, the data into a specific format k1=v1k2=v2, and the Chinese and special symbols are encoded to avoid ambiguitySecond, URL encoding1, UrlEncode ()From urllib import parsefrom urllib Import requesturl = ' http://www.baidu.co
