You'll probably get better support fromthe Maya community than here
since most of us don;'t know anything about Maya's language.

That is presumably the Maya code?
Unfortunately I don't know exactly what it does - I can make
a guess but that's all it would be. For example, is the
indentation on line 2 significant? (It would be in python)
I'm guessing the backtick(`) mean you are executing an OS command?
If so you'll need the python subprocess module to do the equivalent.

If the 2nd line does what I think, the equivalent Python code would
be something like:

if pos[0] or pos[1] or pos[2]:
    # do something here

Can you show us what you tried and what error message(s) you
got(in full)?
