The solution to adding modules in Drupal is confusing (usually when many modules exist ). The status is as follows: 1. after you click the "warranty" button, the page cannot be properly displayed and a blank page appears. 2. refresh the page and issue that many items in the navigation are no longer available, you cannot click another item.
The status is as follows:1. after clicking the "warranty" button, t
Python custom modules, packages, and python custom modules
1. Save a hello. py file in the F:/data/python directory.
Hello. py

>>> Import sys >>> sys. path. append ('f:/data/python') # Add a path, which is one-time >>> import hello >>> hello. hello (5) # Call 5
2. Import the custom module without changing sys. path:
Method 1: place the hello2.py file i
For thinkPHP3.2.0 versions:
Loading modules
$_get[' m '] = ' module name ';
Example: $_get[' m '] = ' admin '; for loading Admin module (backend module)
The controller under the load module
$_get[' c '] = ' controller name ';
Example: $_get[' c '] = ' Admin '; for loading the Admincontroller controller under the Admin module
For thinkPHP3.2.1 and above versions:

Only one module (ng-app= "") can be in Angularjs, and one module may have multiple controllers (ng-controller= "")In their own experiment, JS and the page can be written in a piece, but large-scale project development, it is best to do HTML and JS separation, easy to maintain later.Shown: Ng-app can only have one, multiple controllers in one ng-app, and no meaning when defining multiple Ng-app.Run as follows:"-//W3C//DTD XHTML 1.0 transitional//en" "HTTP://WWW.W3.ORG/TR/XHTML1/DTD/XHTML1-TRANSIT

The implementation of multiple languages is the same: Add strings. resx, strings. en-US.resx, strings. zh-CN.resx and so on, then modify the first constructor to public, manually modify the project file,

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
Modules and packages, modulesModule
A module is a file that contains python definitions and declarations. The file name is the extension of the module name and. py.
In fact, the import module is divided into four general categories:
1. code written in python (. py file)
2 C or C ++ extensions that have been compiled as shared libraries or DLL
3. Pack a group of modules
4. Use C to write and link to the pyth
Add new modules to httpd and add modules to httpd
Sometimes, due to special requirements, you need to add some additional modules to the installed httpd. In this case, you need to use the apxs tool in httpd-devel. To use this extension mechanism, your platform must support the DSO feature, that is, Apache httpd must have a built-in mod_so module.

DefinitionA module is a collection of code that implements some function with a bunch of code, usually one or more functions are written in a. py file, and if some features are complex to implement, then you need to create N. py files, and the collection of N. py files is a module2.

Analysis of errors encountered when importing Python modules and when importing python modules
When a python module cannot be imported, a module may not be installed, a module may fail to be loaded, or it may be subject to a loop import problem. This topic explains in detail.
