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

For cryptographic related operations, the 3.x replaces the MD5 module and the SHA module, mainly providing the SHA1,SHA224,SHA256,SHA384,SHA512,MD5 algorithm (SHA512 the most complex and safest)>>>ImportHashlib>>> m =hashlib.md5 () # Other encryption algorithms in the same vein>>> M.update ('666')>>>m.hexdigest () # 16 binary format Hash'Fae0b27c451c728867a567e8c1bb4e53'>>> M.update ('888')>>>m.hexdigest ()

, remember to install both PIP and add path. If this option is missing, you can install the change again ...-and then all modules can be installed with Pip, under CMD direct pip install Whatevermodule--No network or cannot link the network when you can manually download the module to a path, and then pip install Path\whatevermoduleTo view installed packages:CMD under PIP freezeIt is recommended to install Vscompilertoolsforpython, otherwise the module

042 sorting and filtering of the module grid a sort grid interface sort can be done directly by clicking on the column header, this is very convenient. But there are two more questions to solve: You cannot cancel the sorting to the default, and single and multi-field sorting cannot be easily toggled. To solve these two functions, a SplitButton button is added to the front of the Pagingtoolbar to control these two operations.As you can see in the pictu

Python timeit module for simple usage, pythontimeit ModuleThe timeit module provides a simple method for timing small pieces of code in Python. The module calls the function. stmp indicates the function to be tested, setup indicates the test environment, and number indicates the number of running times. Timeit. timeit (stmt = 'pass', setup = 'pass', number = 10

Python: Regular Expression module, python: Module 1. Regular Expression Regular expressions are used to match strings. Regular expressions have their own rules, which are irrelevant to python and match strings. 2, character group The various characters that may appear at the same position constitute a character group, which is represented by [] in a regular expression.

Python adds its own module path, python module path After entering the Python editing environment, you can use the sys. path attribute of Python to obtain the current search path configuration. You can see that the previously set path is already in the current search path. Then, you can use sys. path. append ('f: \ Pythonchengxu ') to add the path you have created. You can see that the instance is

Asp.net interface-oriented extensible framework-Business Rule Engine extension module and Business Rule extension module As the interface-oriented extensible framework continues to be developed, some function development has encountered a "bottleneck", and there are too many things to be written to death. However, the scalability of the Code to be written is very poor, and you are confused to find the code.

Let's go to the manual to see:It was clearly written to return an object.Then look at the Util module,Nonsense no oh more say, first a little bit of code:/** * Created by Leigood on 2016/8/13.*/varHTTP = require (' http ');varurl = require (' URL '));varUtil = require (' util '));varServer = Http.createserver (function(req,res) {Res.writehead (200,{"Content-type": "Text/plain"});//Plain, let him format the output of the dataRes.write (Util.inspect (Ur

The events module provides only one object: events. Eventemitter."The core of Eventemitter is the encapsulation of event triggering and event listener functionality. 】Each event of the Eventemitter consists of an event name and several parameters, which is a string that usually expresses a certain semantics. For each event, Eventemitter supports a number of event listeners. When an event is triggered, the event listener registered to the event is call
