Question

def do_work():

  print drugs_needed[1][0]

how do i print ASTRAMORPH (this is the first element in MORPHINE)

i NEED to make use of drugs_needed, since this is being passed in from do_work

Answer 1

Can you define MORPHINE this way?

drugs = {
  'MORPHINE': ['ASTRAMORPH',...],
  'HYDROCODONE': [...],
  ...
}

then you can refer to it by

print ( drugs[drugs_needed[1]][0] )
