Understanding ModulesWhat is a module?Common scenario: A module is a file that contains Python definitions and declarations, and the file name is the suffix of the module name plus the. Py.In fact, the import loaded module is divided into four general categories:1 code written using Python (. py file)2 C or C + + extensions that have been compiled as shared libraries or DLLs3 packages for a set of modules4 built-in modules written and linked to the Py

website or pypi, such as the name of the Python Imaging library is called PiL, so, The command to install the Python Imaging Library is:easy_install PILAfter you have waited patiently for the download and installation, you can use PIL.With PIL, it's easy to handle pictures. Just look for a picture to generate a thumbnail image:>>> import Image>>> im = Image.open(‘test.png‘)>>> print im.format, im.size, im.modePNG (400, 300) RGB>>> im.thumbnail((200, 100))>>> im.save(‘thumb.jpg‘, ‘JPEG‘)Other co

Python Pre-loads a batch of built-in modules into memory when it initializes the runtime environment.All pre-loaded modules are as follows:1>>> forIteminchSys.modules.items ():2...PrintItem3 ...4('Copy_reg', 'Copy_reg' from '/users/kris/git_space/pyv/lib/python2.7/copy_reg.pyc'>)5('Encodings', 'Encodings' from '/users/kris/git_space/pyv/lib/python2.7/encodings/__init__.pyc'>)6('site', 'site' from '/users

Python modules and packages are simply equivalent to namespaces.1,python module A python module is a file with functions, variables, etc.Import ModuleModules-MethodsFrom module Import functionFrom module Import *__name__ = = ' __main__ ' is the decision to run the module yourself or be called to executeIf __name__== ' __main__ ':Print (' Login main program run ')ElsePrint (' login is running line ')2,python BagThe collection of

default is.) Can be used in name and is replaced with rep (the default is the delimiter of the system directory) during the lookup. For example, path is Copy Code code as follows: "./?. Lua;. /?. Lc;/usr/local/?/init.lua " To find FOO.A, you will try to find the file Copy Code code as follows: ./foo/a.lua,./FOO/A.LC, and/usr/local/foo/a/init.lua This means that LUA supports a hierarchical module name.The third function is used to get the loade

Before the introduction, a simple say asp.net service side gzip compression module function and working principle, a lot of people write the page because of the use of a lot of JS special effects or put a lot of large dynamic ads caused the page or script bulky, Usually use some compression tools local to the page or script to a certain compression and then upload to the server, but such compression tool general compression rate is limited, optimization is not obvious, the compression module des

Under the Ubuntu system, we usually use apt-get to get everything done, easy and quick. But if you want to add additional modules to the Nginx, you need to recompile. Compiling nginx from the source code will manually supplement some of the files provided by the Debian package, such as startup scripts, Logrotate, and so on.Get the extra modules Take Pagespeed, upload module as an example. Get the Pagespee

This document describes the classes and functions so need to implement in a Native Client module in order for Chrome To load, initialize, and run it. The requirements is the same regardless of whether or not the module uses PNACL, but depend on whether the module is writ Ten in C or C + +. Introduction Native Client modules do not has a main () function. When a-module loads, the Native Client runtime calls the code in the module to create an instance

When I first learned about joomla, I was always confused about the relationship between modules and components. The two are similar and different. I once made a big difference in the relationship and difference between them. What is the difference between them? These problems can be felt in practical application. This article will try to use examples on this site to talk about these problems, so as to have an intuitive feeling, let the beginners put t

Modules in JavaScriptBefore learning the Typescript module, let's look at how the modules in JavaScript are implemented.Benefits of the moduleFirst of all, we need to understand the benefits of using modules what? Modular, reusable; encapsulating variables and functions; The following example is a module that is implemented using javascript:1 va

Installation of PHP and its modules We know that ASP operation requires PWS or IIS server support, without these two servers, it can not run. ASP server-supported installations typically include ASP The language interpreter and the WEB server. In the same way, the installation of PHP is divided into two parts: one for the installation of PHP and its modules, and two for the Web server. Installation of PHP

0. DescriptionModules are used to organize Python code methods, while packages are used to organize modules, making the best use of packages and modules will facilitate the development of large, clearly structured programs. 1. What is a moduleThe so-called module, in fact, is a. py file that contains a specific function code, in this. py file, the following code types are mainly: Classes that

in thepython Development , how do I install the python module? Certainly many beginners are wondering why install the module? becausethese modulesinis not included in python 's default code and needs to be downloaded and installed externally. For example , pygame version of Windows , directly double-click the installation can.

A simple drive The use of the module can make the Linux kernel easy to crop, according to different application needs to get a minimum kernel, while debugging kernel driver is also more convenient, such as if the debug i²c driver, if not the mode of module, then every time you modify the I²c driver will have to compile the entire kernel, for compiling debugging is extremely time consuming, using the module , a simple insmod will load the module into the kernel, if it does not feel appropria

Modules are the basic way to organize your code in Python. Python scripts are saved with a text file with the extension py, a script that can be run separately, or it can be imported into another script. We say that the script that runs in the import other script is module.1. How to import ScriptsThe name of the module is the same as the script name, and if you define four operation operations functions, such as subtraction, in a file named operation.

　　This series of tutorials is intended for individual learning notes, and if you want to browse may require other programming language basics (such as C), why? Because I write rotten ah, only I can understand!! Module#1. The module allows you to logically organize your Python code snippets, analogous to the jar packages in Java.#2. Assigning the relevant code to a module will make your code a better and easier to understand.#3. The module is also a Python object with a random name attribute
