Replacing or deleting items in list using slices


I understand lists are mutable. And slices get a copy of original list. In the following code, list and sliced_list are different.

list = [1, 2, 3, 4, 5] sliced_list = list[::-1]

So, I don't understand about replacing or deleting items in list using slices. Slices are copy of list, replacing or deleting slices can't affect original list, i think.

Could you explain about this?

Thanks, Ross

You're right, modifying "sliced_list" should not affect "list".

If you saw something that caused a doubt, please show the exact steps needed to reproduce it.
