l2 = [5,6,7,8]

 

print "List Manipulations L1 : " ,l1

print "List Manipulations L2 : " ,l2

 

l1.reverse()

print "\nList reverse : ", l1

l1.append(l2)

print "\nList append (Create multi diamension list)  : ", l1 

 

print "\nElement [4][2] is : ", l1[4][2]

 

l1 = [1,2,3,4];

l2 = [5,6,7,8];

 

l1.extend(l2)

print "\nList extend (Create single diamension list)  : ", l1

 

l1.pop()

print "\nRemove last element from list -pop() : ",l1

 

l1.pop(2)

print "\nRemove 2nd element from list -pop(2) : ",l1

 

l1.insert(2,3)

print "\nInsert element into list -insert(,i,val) : ",l1

 

l3=range(5,27,2)

print "\nCreate a range of integers - range(init,end,step) : ",l3
