A python file is a module that uses a separate namespace, but it is clearly not enough to use modules to define Python functionality in practice. Because a large system of thousands of tens of thousands of modules is a normal thing, if all together is obviously not good management and there is a possibility of naming conflicts, so Python also appeared a concept of a package.First, the package introduction in PythonA package is a way to create a Python

After the CentOS installation, some modules are turned on by default, but some modules are not required. IPV6, for example, is not yet popular in China.How do I close IPV6?The methods described below can also be used when closing other modulesThe first step:Find Module NameUse the command: Lsmod view the system-initiated module to find out what we needThe 2 modules associated with IPV6 are net-pf-10 IPv6Ste
Import ModuleNameIf you want to use a method in the ModuleName module, it is Modulename.method (Point method),For example, a method in ModuleName is set, then a modulename.set is used.If you want to use set directly, you can use the From ModuleName import set, and you can use the Set method directly.If you import in a module like this, you define the same method in this
The UUID is a 128-bit globally unique identifier (Univeral unique identifier), typically expressed in the form of a 32-bit string. Sometimes also called a GUID (Global unique identifier). Python has its own UUID module for the generation and management of UUID. (It is unclear from which version.) )The UUID module in Python is based on the UUID of information such as MAC address, timestamp, namespace, random

One of the most important functions in ansible is the ability to execute AD-HOC commands, and some people may not understand the meaning of the word ad-hoc, which means instant meaning, or arbitrary meaning.In contrast to the Ansible playbook function, playbook is suitable for batch deployment environments and is generally not frequently changed. The Ad-hoc command applies to operational scenarios such as business change, such as deploying a configuration file in bulk, restarting a service, inst

To solve the problem of global objects, we evolved to the third phase, with module objects and Iife (execute functions immediately)Disadvantages of this approach:Although the exposed global variables are less, only this one module object, can be said to solve the problem of pollution global variables, but the dependency is not resolved, because Iife
