When executing the following code, I would expect the 3 to be removed from "list_copy" while "list_original" remains unaltered. However, list_copy.pop() removes the 3 from both lists. If an index is specified for pop, this behavior occurs as well. list_original = [1,2,3] list_copy = list_original list_copy.pop() Please let me know if I can provide any other information. |
