Python

Memorandum Mode:Capture the internal state of an object without compromising encapsulation, and save the state outside the object. In this way, the object can be restored to the previously saved state. It is similar to the prototype mode, but

Combination Mode:The "part-whole" hierarchy makes the use of a single object and a composite object consistent. # Encoding = UTF-8 ## by Panda # combined mode def printinfo (Info): Print Unicode (Info, 'utf-8 '). encode ('gbk') # component:

The last time I talked about how to view the current view and parameters, remember a string'* (Int *) ($ ESP + 4 )'It's really uncomfortable. You can use the lldb script. I wrote a script (download) to create a recursive query, because it is not

A useful automatic tool library has been found recently: Http://code.google.com/p/pywinauto/ Http://sourceforge.net/projects/pywinauto/   It's a little time! In addition, Perl has similar libraries, which are similar.   It is very convenient

In the NLP (Natural Language Processing) field, Python has a good reputation, so I want to learn about it. The first step is to configure the python environment on the computer. The Python editor is too simple to use, so you need to configure pydev

GenerallyCodeThe code used to call a class to create an object is rarely stored in the same file. This problem occurs when one file needs to call another independently stored class file to create an object. There are few introductory books and

Today in a forum to see the application of python for Chinese clause source code (http://www.corpus4u.org/forum/showthread.php? S = 86a8e08ccda003206c8f8d66c011df67 & t = 8662 & page = 2). The principle is very simple. post it to spread it. Note is

These days I couldn't help playing with python. This is really a pity, but I have suffered a lot in the process of searching for IDE!   Python has been developing for many years, and the IDE is also mixed and varied. It is even harder to find a

Adapter Mode:Converts an interface of a class to another interface that the customer wants. So that those classes that cannot work together due to interface incompatibility can work together.Application scenarios: You want to reuse some existing

Import of functions in the module or module in Python: 1. Import: Module name 2. Import: Module name as new name 3. From Module name import function name Note: 1. Import the entire module. When using functions in the module, you must add "module

Installing Python cx_oracle module on Ubuntu 10.04 Step 1: Install prerequisite Software You will need to have the following packages installed to get Oracle Instant Client and cx_oracle installed:* Build-essential* Unzip* Python-Dev* Libaio-DevSo

Decoration Mode: Dynamically add some additional responsibilities to an object. In addition, the decoration mode is more flexible than the subclass generation.Application Scenario: It is applicable to "newly added functions only to meet certain

The biggest advantage of the simple factory mode is that the factory class contains the necessary logic judgment. The client only needs to provide selection conditions, so that the client does not need to know the specific product

Prototype: Use a prototype instance to specify the type of the object to be created, and copy the prototype to create a new object.The prototype is essentiallyClone object, So inObject initialization operations are complex, which can greatly reduce

Proxy: provides a proxy for an object to control access to this object.Note:: The class diagrams of the proxy mode and the policy mode are similar, and the implementation methods are the same, but the application scenarios are very different,

Observer Mode: Publishing-subscription mode.It defines a one-to-many dependency, allowing multiple observer objects to simultaneously identify a topic object. When the status of this topic object changes, it notifies all observer objects so that

Singleton Mode: Ensure that a class has only one instance and provides a global access point to it. There is only one instance for a class:1. Let a global variable make an object accessible, but it cannot prevent external instantiation of multiple

Command mode: Encapsulate a request as an object so that you can parameterize the customer with different requests. It supports request queuing, request logging, and unrecoverable operations. Advantages: Separates the objects that request an

Interpreter mode:Given a language, it defines a syntax expression and an interpreter. This interpreter uses this 'representation' to explain sentences in the language. Application scenarios: If a particular type of problem occurs frequently enough,

Visitor Mode: Indicates an operation that acts on each element in an object structure. It allows you to define new operations that act on these elements without changing the classes of each element. The visitor mode appliesRelatively stable Data
