1. Module Import methodCommon scenarios:A module is a file containing python definitions and declarations, and the filename is the suffix of the module name plus the. Py , and the import module allows for the reuse of the function.Import loaded modules are 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
cannot from *__all__ only shows, from * can only get __all__ specified in, other hidden.In Python, the from * will look for a list of __all__ in the module, copy the variable name in it, and if not, the from * will copy all command names without an underscore at the beginning.How do you think the __all__ list is stored in the module???8. Mixed usage mode: __name__ and __main__This is a special module-related technique that allows you to import files as modu
One, module conceptIn the process of computer program development, as the program code more write more, in a file code will be more and more long, more and more difficult to maintain. In order to make the code easier to maintain, we grouped many functions into separate files so that each file contained a relatively reduced number of codes. Many programming languages use this form of organization code. In Python, a. py file is called a module. What are the benefits of a module?The greatest benef

Dojo is a very powerful object-oriented JavaScript toolbox, suggesting that readers should be able to add JavaScript to programming with OO, which is very useful for you to read Dojo source later.

The Python language has very powerful functions. In addition to classes, there are also the concepts of modules and packages. This is a bit like perl. This article mainly introduces packages and modules, for more information, see the Python language. In addition to classes, there are also modules and packages. This is a bit like perl. Here we will briefly talk ab

In Windows NT/2000 paging mechanism, I have described in detail the non-Paging Memory Internal Mechanism of Windows NT/2000 on the X86 platform, the address space can be divided into process space and system space. Each process has its own process space, while all processes share the same system space. Therefore, when Windows NT/2000 involves module management, it also involves two parts: Process private

1 , what is a kernel module? The kernel module is a Linux-provided mechanism that allows dynamic loading into the kernel while the kernel is running, with two features:1) kernel module itself does not compile into kernel image, effectively control reduced kernel image size2) Once the kernel module is loaded, he is exactly the same as the rest of the kernel.2 , why do I need kernel modules? If all functions are compiled at the kernel compile time, the

Starting with the Lua5.1 version, new support is added to modules and packages, but modules and packages are defined and used using require and module. Require is used to use modules, and module is used to create modules. Simply put, a module is a library of programs that can be loaded by require. Then we ge

Apache has been installed and put into operation, but later found that some modules did not load, of course, there are two ways:1. One is to completely recompile Apache, then install2. Compile the module as so file and load the extension module with the loadmodule instruction.This is just the second way.Scenario: You now need to enable Apache's deflate module, which is compressed output, to speed up website downloads and save network bandwidthServer R
