pointer sorting by swapping values or by pointer itself

nextpointer=current.getNext()              #storing next pointer of of current node
sortednext=sortedCurrent.getNext()         #storing next of sorted current node
sortedLastCurrent.setNext(current)      #set current to next of sorted last current node
current.setNext(sortednext)                #set next of current to sorted next
currentpre.setNext(sortedCurrent)          #set next of currentpre to sorted current sortedCurrent.setNext(nextpointer)         #set next of sorted current to next pointer
sortedCurrent=current                      #set sorted current to current pointer

temp=node.getData()
node.setData(node2.getData())
node2.setData(temp)
