Since the command line argument is optional I don't think it should be 
considered and exceptional condition if it's missing, so the "if" block 
looks better to me. No idea if this is more pythonic.

Ok, so you should do:

try:
     x = 1/i
except ZeroDivisionError :
     do_something_if_zero()

instead of

if (i == 0) :
   do_something_if_zero()
