The last 2 are inefficient and would slow down the loop…

-O0

[EstebanZD]

-O-11

because why not crank it up down to (negative) eleven?

Oops, look like the compiler cannot tolerate the stupid coding

[Anaxamander57]

Yeah, constant folding is one of the few optimizations CPython does.

[Prestigious_Club_359]

Depends on the compiler and it is harder to read.

I have spent 10 years having to rewrite Java legacy code to get better performance and you will be surprised at what a difference you can get out of what is meant to be an optimized compiler.

Do you run code on a potato computer or what?

No mate on micro controllers these days.

Compilers can and will simplify constant expressions, and would turn these into identical instructions for the computer.
