Hi i am a student and working on GNU..I have a python code which i want to
run in GNU radio companion but i am unable to search for the right block to
execute that code...can anyone help me with that??When I execute the same
python code(not in GNU), I get the following error:

AttributeError: 'top_block_sptr' object has no attribute 'wxgui_'

If anyone knows about this,plz send a mail to alihanif799@gmail.com....thnx
in advance..the code is as shown:
