[Baypiggies] running code in different stack frame

[Shannon -jj Behrens]

Raise and catch an exception. Use the exception to get a hold of the
caller's stack frame so you can play with its locals. I used this trick once
to implement a templating library called evalstr.

Hi,

Is there anyway to specify that I want a block or function to work in
different stack frame in python ?
I'm thinking about something like this:

def check_something(magic_stack_frame, blah):
    if blah > 10
      return "Error...."
    else:
      # do something
    return


def myf():
   blah = 20
   check_something(current_stack_frame, blah)
   print('should not be here')

In this case, I don't want to see the message 'should not be here'.  The
return "Error ...." should be done as if check_something
is in the same stack frame of myf() instead of check_something

Thanks,
