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. The method for a

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. 1. The module is not installed or the path is incorrect. ImportError: No mudule named myModule There are two possibilities. One is th

. 3, Urllib, URLLIB2　　Urllib2 can accept a request object and use this to set the headers of a URL, but urllib only receives one URL.　　This means that you cannot disguise your user-agent string and so on. The Urllib module can provide a method for UrlEncode, which is used to generate a get query string, and URLLIB2 does not have such a function.　　This is why Urllib and urllib2 are often used together. (1) Urllib2.urlopen (Url[,data,timeout]) is used to obtain Web content (2) urllib2. Response (U

Introduction to two built-in modules in Python and two built-in modules in python After using Python for a while, we can say that the basic unit of Python is the module. When using the module, we generally use the import Statement to import it, however, when we haven't imported any modules, we can use such functions: int (), str (), len (), range (), and where c

Some basic knowledge about modules in Ruby and basic knowledge about Ruby modules A module is similar to a class. It can also be called a class that cannot be instantiated ". Because the Class is a subclass of the Module Class, it may be better to say "Class = Module + instantiation Capability. What is the so-called module used? There are two main types of functions: Mix-in and namespace. Mix-in is actually

We have already learned how to insert an empty module into the project of VBA through previous introductions. As you can see from the Insert module, there are two kinds of modules-standard module and class module. A class module is a special module that contains the definition of a class, including its properties and methods. In the following will be an introduction and description. As the project becomes more and more complex, we are likely to have

Python-import facilitates the implementation of the required functions (modules), python-Modules The module enables you to logically organize your Python code segments. Assigning relevant code to a module makes your code easier to use and understand. The module is also a Python object and has random name attributes for binding or reference. Simply put, a module is a file that saves Python code. The module c
