[issue27668] list illogical affectation

[SilentGhost]

SilentGhost added the comment:

Because elements of the tab list are the same list. And since list is a mutable type, modifying list object will be visible to via all the reference / names that point to that object. There are various ways to work around this behaviour, typically a list comprehension is used.

P.S. Please don't add spurious components to the issue, it adds people to the nosy list.
