[issue23406] interning and list comprehension leads to unexpected behavior

[Steven D'Aprano]

Steven D'Aprano added the comment:

This is already a FAQ:

https://docs.python.org/2/faq/programming.html#how-do-i-create-a-multidimensional-list

I guess this bites every beginning Python programmer, but it's a natural, and desirable, consequence of Python's object model and the fact that * does not copy the list items.
