In the actual writing program, the variable type is often judged, in addition to the type (variable) This method, you can also use the isinstance method to determine:#!/usr/bin/envpythona=1b=[1,2,3,4]c = (1,2,3,4) d={' a ': 1, ' B ': 2, ' C ':3}e= "abc" ifisinstance (a,int): print "Aisint" else:print "Aisnot int "Ifisinstance (b,list):print" Bislist "else: print "Bisnotlist" Ifisinstance (c,tuple): print "

RepeaterIt is a device that connects network lines and is often used for Bidirectional Forwarding of physical signals between two network nodes. Relay is the simplest network interconnection device and belongs to the physical layer. BridgeIt is a layer-2 (data link layer) device used to isolate conflicts, but not broadcast. It is often software-based and rarely used now. VswitchIt is

Introduction of Ansible 1.ansible Ansible is a new automated operational tools, based on Python research and development. Combines the advantages of many old operational tools to achieve the bulk operating system configuration, batch program deployment, batch operation commands and other functions. Only the Ansible program is installed on the management station to configure the IP information of the managed host, and the managed host has no client.

Do not reprint advanced playbook without written permission Finding files with variablesAll modules can take variables as part of their arguments by dereferencing themwith {{ and }} . You can use this to load a particular file based on a variable.For example, you might want to select a different config file for NRPE (
