Why would you mention this in the context here?

I remain confused by this oft repeated mantra regrading the use of
copy. Are  you saying that the need to copy a list indicates flawed
logic, or that doing it otherwise than by list[:] is flawed?

I have to assume the latter, but am willing to learn otherwise.

But if the latter....

Why even mention copy in this context?

But once mentioned, I need to ask then why the use of copy(list) is
flawed.

That is, are there reasons beyond the obvious, of extra keystrokes.
And speed optimization, to the extentf it might be considered material
in a particular instance.
