Python interface: is there any way to...

[Paul Smith]

I'm wondering if there are ways to detect, from within the Python
extensions for GDB, these things:

Can I determine whether I'm working on a core file, versus working with
a live process?

Can I determine whether my Python methods are being invoked from within
a variable "pretty printer context", versus some other context such as
the result of a function call from the prompt etc.?

Thanks!
