Re: [Discuss-gnuradio] QA code for python hierarchical block

[Miklos Maroti]

Hi Cinaed,

Thanks for the pointer. This is what I found:

- in qa_polar_encoder_systematic.py we have
import fec_swig as fec
from extended_encoder import extended_encoder

- in extended_encoder.py we have
import fec_swig as fec

I assume that people use the extended_encoder from their own code (or
from GRC), so I would have just used "import fec" within the
extended_encoder.py. It seems that I do not fully understand the
difference between "import xxx" and "import xxx_swig", I thought that
the later is only for debugging, but apparently it includes only the
cpp wrappers.

So in an xxx OOT module I should always import xxx_swig (and never
import xxx) and import python files by name if I want to use other
hierarchical modules. Is this accurate?

Best,
Miklos
