It's just a list of lists.

He was answering a hypothetical. He wasn't suggesting that was valid
syntax today.

Genetic algorithms usually involve the manipulation of bit strings.
Genetic programming usually involves more program-like constructs, such
as Lisp s-expressions.

That is an exceedingly bad idea. Type:
__import__('sys').exit(),
in the prompt and see what happens.
You _never_ want to run `eval` on an untrusted string. Never.

get help defining) how to calculate them. As it is you've not given
nearly enough information to answer your question.

to define more clearly what properties of this
negative function you want to narrow it down beyond that.

efine them up front, it results in a very unsatisfactory
guessing game of proposing a function, you telling me what's wrong with
it, and repeat until either or both of us get bored.
And, by the way, this is a question about mathematics, and so has
nothing to do specifically with Python.
whether their identity is shared with other objects in other contexts is
never significant.

Oops, the interpreter exited.
Just when you think you've covered all the bases, you haven't.

oit I gave wouldn't have worked so easily.
The bottom line here is that you shouldn't even try to go through the
exercise of seeing if you can bullet-proof a solution using eval;
instead, you shouldn't even try.
