[issue33636] Unexpected behavior with * and arrays

[Steven D'Aprano]

Steven D'Aprano <steve+python at pearwood.info> added the comment:

This is not a bug, it is the documented behaviour: the * operator does not copy the lists, it duplicates references to the same list. There's even a FAQ for it:
