I think that python could be very useful in a lot of
areas of industrial control (often there's no
hard-realtime constraint and you can use a consumer
PC for the software).

The only thing that scares me a bit about using python
is that industrial control is (at least for the part
I'm seeing for my job) terribly closed-source.
I see for example that its very very common to use
even hardware locks for the software.

I'm not my boss, and could be hard to explain that it's
not a problem using an interpreted language that is
easily decompilable and using modules with licenses
that are basically nonsense in this context.
To a very specific question I was answered here that
the best thing to do before using e.g. pygame in a
closed source product is consulting a lawyer; and
that obtaining a clear answer would have been a sign
that the consulted lawyer isn't a good one.
