[Discuss-gnuradio] constellation mapping

I want to do constellation mapping in pyhton.  I have code that does a 
gr.packed_to_unpacked_bb and then gr.chunks_to_symbols_bc using a constellation 


My understanding is that this is the constellation mapping for QPSK.  I want to 
do constellation mapping for BPSK and 64-QAM.  I don't have a lot of GNU radio 
experience so I'm not really sure how to do this.  Is all I do is change the 
array (all the possibilities from 4+4j to -4-4j for 64-QAM and 1+0j to -1+0j 
for BPSK) and the code will do the rest to map the data for the other 
modulation schemes?

Thanks for the help in advance,
