Slices can be updated using the bracket operator:
aList = [1, 2, 3, 4, 5, 6] aList[1:4]=[9] # replace elements with one element with value 9 print aList aList[0:0]=[0,0] # insert two elements with value 0 print aList aList[1:3]=[] # delete two elements print aList
prints:
[1, 9, 5, 6] [0, 0, 1, 9, 5, 6] [0, 9, 5, 6]
