Learning python for a short period of time, always stuck in a simple grammar, can't really appreciate the power of Python. Today we learned the reference method for custom modules. When referring to the module, the compiler will first in the current directory, then go to Sys.path, Python's installation directory to find the module you refer to, if not, will be an error.In the first case, your module is in the same directory as the module you want to u
Module--Code encapsulationModules are the basic way to organize your code in Python. Python scripts are saved with a text file with the extension py, a script can be run alone, or it can be imported to run in another script, which we call Modules (module) when the script is imported and run. That is, all the code files we write in Python can be called modules.When importing, the module name is the same as the file name of the script, for example, we w
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

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

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

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

In the first part of this article, I talked about what modules are, why developers use them, and how to implement modules in your program in different ways.
In this second part, you will answer what the bundle means: why bundle, bundle different methods, and the future development of modules in web development. 1. What is
xhtml| Tutorial
The XHTML modular model defines the XHTML module.
Why XHTML is Modular
XHTML is a simple and huge language. XHTML contains most of the features that Web developers need.
For some special purposes, XHTML is too big and complex, and for other purposes it's too simple.
By dividing XHTML into modules, the consortium has created several sets of small, well-defined XHTML elements that can be applied independently to simple devices and incorp
usually assign it a local name:>>> fib = fibo.fib>>> fib (1)1 2 3 5 8 13 21 34 55 89 144 233 377In-depth modulesA module can contain execution statements as a function definition. These statements are typically used to initialize a module. They are only executed once when the module is first imported.Corresponds to a global semantic table that defines all the functions in the module, each with its own private semantic table. Therefore, the module author can use some global variables in the modu
In the previous article, we introduced the concept of pear, coding rules, simple use method, you may have a preliminary understanding of it. This time, we'll introduce the functionality and usage of some of the modules in the existing Pear library.
First, naming convention
Before we get to the existing Pear module, let's take a look at how Pear organizes its classification and naming conventions. The modules
Python full-stack Development 7. Module and several common modules and format knowledge supplement, pythonformatI. Module Classification
One of the reasons for the popularity of Python is that it has a large number of third-party modules, so we don't have to re-create the wheel from scratch when writing code. Many of the functions to use have been written and encapsulated into libraries, we only need to cal
