I wonder if it just can't find the magma password file.  After skimming

http://magma.maths.usyd.edu.au/magma/prot/prot.html

it looks like you can (must?) set the MAGMAPASSFILE environment variable. Can you try:

os.system('export MAGMAPASSFILE=<wherever this is> && magma')

or

import os
os.environ['MAGMAPASSFILE']
