How to access an absolute address through Python?

[volcano]

Can it be done, and if yes - how?

Define address. Are you talking about URLs? File paths? Postal
addresses? Memory addresses? Whatever addresses?
I'm afraid the people on this list can't read your thoughts...

I presumed that "absolute" address somehow qualifies my question. If
it is not - I was talking about physical computer memory, on PC - to
be more specific.

In pure Python it's not possible and even in C it might be difficult to
get an absolute *physical* memory address unless you run DOS. Modern
operating systems tend to use some virtualisation of memory. :-)

What's your goal? What do you expect at the memory address you want to
access?

My goal is to sync program with external equipment through a register
defined as an absolute physical address. I know how to do it from C -
was curious if it may be done from Python. Can it be done?

Thanks, Mark

Your best bet will be to create a C library callable from Python to do it
for you. There may be such a beast in existence already, but it should not
be hard at all to do, given the simplicity of the requirements.

No. You'd have to use a compiled extension.

Steve, Fred, thank you. This is exactly what I have done, though I did
hope for shortcut. Life is tough:)!

Well, you don't necessarily have to deal with the C API or ctypes; it
may be enough to invoke an external program that accesses the
necessary memory address.
