Python's urllib and urllib2 modules do all the work associated with requesting URLs, but they provide different functionality. The two most significant differences between them are as follows: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

Common built-in modules in Python (datetime,logging,os,command)Import module in Python using keyword import1, if you are importing files locally, use the following directly:Import filename2, if the import is a package, the package below must be a__init__.pyFiles can be imported, otherwiseError, only have the__init__.pyFilePythonThe parser will take this directory as a package.Common formats for commonly used import modules:form XXX Import xxxImport xx

Install PiL After waiting for download and installation, you can use PIL. With PIL, it's easy to deal with pictures. Grab a picture and create a thumbnail: >>> import Image >>> im = Image.open (' test.png ') >>> print Im.format, Im.size, Im.mode PNG (MB) RGB >>> Im.thumbnail ((m)) >>> im.save (' thumb.jpg ', ' JPEG ') ) Other commonly used Third-party libraries are also MySQL-driven: Mysql-python, a numpy library for scientific Computing: NumPy, template tools for generat

poor, the modular mechanism is to make up for this flaw. A module is a stand-alone program that can be compiled separately, but not run independently. It is linked to the kernel as part of the kernel running in the kernel space at runtime, which is different from the process running in user space. A module is usually composed of a set of functions and data structures to implement a file system, a driver, or other functions on the top of the kernel. In short, a module is a code block that provid

, and so on, you need to use the email module and its child modules. Here's a look at email packets, which are used to manage email messages, including MIME and other RFC 2822-based message formats. The main feature of an email packet is that it is a separate module to parse and generate the email information inside it. A MIME message consists of a message header and a message body, in which the message header and the message body are part of the mes

In other forums, a lot of the installation of Perl modules, in fact, sometimes very easy to install failure. Especially on Windows, such as tools such as cpan,ppm can be used. At the command line Enter CPAN, eject cpan>, and then enter install module name, such as I want to install Lwp::useragent::P roxyany Input install Lwp::useragent::P Roxyany, but often there are mistakes, this way is very troublesome. So exit; go to PPM, Input ppm is a toolbar th

The small network has two modules: the company Internet module and the Park module. The company's Internet module has a connection to the Internet, and also ends up with VPN and public services (DNS, HTTP, FTP, SMTP) information flow. The Park module contains layer 2nd switching capabilities with all users as well as admin with intranet servers. A discussion of this design is premised on the use of small networks as the head end of the enterprise. (Co

Concepts and usage of Modules-general Linux technology-Linux programming and kernel information. The following is a detailed description. 1. What is modules? The literal meaning of modules is the module, which refers to the kernel modules. Simply put, a module provides a function, such as isofs, minix, nfs, and lp. Tr

probability of the function and variable having the same name becomes smaller and less prone to collisions.4. They can also refer to other modules (built-in modules, three-party modules, custom modules):Built-in modules: Systems already included. For example: OS, Math,rando
