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
