. 3, Urllib, URLLIB2　　Urllib2 can accept a request object and use this to set the headers of a URL, but urllib only receives one URL.　　This means that you cannot disguise your user-agent string and so on. The Urllib module can provide a method for UrlEncode, which is used to generate a get query string, and URLLIB2 does not have such a function.　　This is why Urllib and urllib2 are often used together. (1) Urllib2.urlopen (Url[,data,timeout]) is used to obtain Web content (2) urllib2. Response (U

A Module introduction1. What is a module?#常见的场景: A module is a python file that contains a set of functions, such as spam.py, which is named spam and can be used via import spam. #在python中, the module is used the same way, but in fact, the module can be divided into four general categories: 1. py file 2, written in Python, has been compiled into a shared library or DLL's C or C + + extension 3 folders that organize a series of modules together (note:

The examples in this article describe the Python creation module and the method of module import. Share to everyone for your reference. The specific analysis is as follows: The Python Learning manual reads: Define modules, just use a text editor, enter some Python code into the text, and then save with a. py suffix name, any such file would be considered a Python module. For example, the following code is entered into a file and can be viewed as a

Since some PDF files need to be downloaded from a Web page, there are hundreds of PDF files to download, so it is not possible to download them manually. Python has the relevant modules, so I wrote a program to download the PDF file, and by the way, I was familiar with Python's Urllib module and ULRLLIB2 module. 1, the problem description A PDF file containing hundreds of papers from the http://www.cvpapers.com/cvpr2014.html is required, as shown in

I. How to download the kernel source code: 1. Download the kernel source code in ubuntu: apt-get install linux-source Find the kernel source code package: apt-cache search kernel-source. Then, install the corresponding source code package and run apt-get install linux-source directly. In this case, the downloaded kernel source code may be different from the current kernel version (My ubuntu kernel is 2.6.35-22, and the downloaded kernel is 2.6.35.11 ). 2, download a specific version of the Li

Search for and install Python modules and search for python modules 【Import Module] Unlike # include in C, the import Statement in Python does not simply insert a file into another file. The import operation is a running operation. When the program imports a specified file for the first time, it performs the following steps, 1.Find the module File 2.Compiled into bits 3.Execute the code in the module to cre

First, what is the module　　In order to write maintainable code, many functions are grouped into separate files, so that each file contains relatively few code, and the programming language uses this kind of organizational method. In Python, a. py file is called a module.Ii. What are the benefits of using modules? The greatest benefit is that the maintainability of the code is greatly improved. Second, writing code does not have to start from
