Transferred from: Http://www.elias.cn/Python/PythonPathThe article is simple and understandable.Sometimes the program we are modifying or debugging will be a library, for the convenience of modification, we may not want to put it under the site-packages, but rather to keep it in the original engineering directory, to facilitate the management of the IDE and version control tools. So how do you get the Python runtime to find this library?In principle, the Python runtime is essentially a traversal

This problem occurs when you add a project to Tomcat today: Tomcat version 6.0 only supports EE 1.2, 1.3, 1.4, and Java EE 5 Web ModulesThe reason for this is that the project used to be TOMCAT7. X now changes to tomcat6.x. (It should be possible to upgrade Tomcat to 7.x, but there is a tomcat6.x for the project now.) So I keep tomcat6.x)The workaround is to modify version= "3.0" in Org.eclipse.wst.common.project.facet.core.xml under the. Settings folder under the project to version= "2.5" Resta

Example of installing the HTTPLIB2 module1 Download ModuleDownload a compact Package "Httplib2-0.4.0.zip" for You in "https://code.google.com/p/httplib2/"2 Unzip the downloaded compressed package "Httplib2-0.4.0.zip" to a directory3 Configuring Python's operating environment under DOS(Before you need to configure the system environment variables, add the Python installation directory after the system environment variable path, such as c:\python2.7)4 dos Install HTTPLIB2 moduleGo to the Httplib2-

With search, you find a file named Org.eclipse.wst.common.project.facet.core.xml in the. Setting folder under Project, which is configured with various version information. At this point, the problem is solved by modifying the file according to the native configuration.For bugs like me, you can download Tomcat 7. 0 solve, but I am busy trouble, simply in the configuration file Tomcat 6 supports only 1.2, 1.3, 1.4, and Java EE 5 Web Modules

The traditional multi-module approach is to establish domain, DAO, service, etc., this way is divided according to the software architecture, now more should be inclined to follow the function to decouple, module can be configured as a jar in the early stage, can also establish a unique page, independent site, Through sub-domain access, each function module decoupling, the trend of micro-service architecture, the following is handled in this wayWhen clicked, Idea generates archetype, but it is v

When writing a Python program, write the module while debugging. Debugging is done in Python's own command-line terminal. However, when the code in the module is modified, the original debug terminal is executed to the new modified content in the module.I used to quit and re-enter the debugging environment, behind Baidu, found a better way to reload the function reload () can reload the module. Like what:This allows you to modify and reload and re-debug.It is also necessary to note that if a dep

are like importedIf the class is like a module, then there should also be an import-like concept. In a class, this concept is called instantiation, and when a class is instantiated, it gets the object of a class.Create a class;Class MyStuff (object):def __init__ (self):SELF.A = ' How is it? 'def apple (self):Print ("I am classy apple")b = MyStuff () #类的实例化B.apple () #调用类的方法Print b.a# properties of the printing classAnalyzing the instantiation of a class this sentence actually python has done a

run Python:>>>from package1.subPack1.module_11 Import Funca>>>funca ()Funca in Module_11In this way, we have correctly called the functions in Module_11 according to the package's hierarchical relationship.The careful user will find that sometimes a wildcard character * is found in the import statement, and all elements in a module are imported, how is this implemented?The answer is in the __init__.py. We wrote it in the __init__.py file in SubPack1.__all__ = [' module_13 ', ' Module_12 ']And t

But I still recommend using PTH files to add.The module and the execution file directory structure are the same:02执行文件main.p

The Deque module is an item in the Python standard library collections, which provides a sequence that can be manipulated at both ends, which means that you can perform add or delete operations before and after the sequence.1. Create the deque sequence: from Import dequed=deque ()The 2.deque provides a list-like method of operation:d=deque () d.append (3) d.append (8) d.append (1)So at this pointD=deque ([3,8,1]), Len (d) =3,d[0]=3,d[-1]=13. Use pop on both ends:D=deque (' 12345 ')SoD=deque (['1
