All programming languages will be able do anything and everything once they can do anything and everything....doesn't mean it couldn't be done if the Python standard provided a means for it to be done.
When, and if, that happens it won't then be possible to say it cannot be done with Python.
Perhaps there is something about Python I do not know.
What is it about the current specification of Python's syntax and semantics that prevents it from accessing machine memory and registers?
Good question. No idea.But whose problem is that, where is the cause, and what is the solution ?
It's no different to a DJ working for a station playing music they don't like, exactly like a musician...
My take on it is that, for most, a career in programming is more like any other work. One works in whatever factory or office one can. One does not get to make the big decisions, one puts up with it and takes the pay check.
Then it's off to the pub with your work mates to complain about it all. Which in this case includes a moan about the tools one is forced to use, languages, operating systems, version management systems, etc, etc.
