You can do it shorter, not sure that it also qualifies as better....

d = { True : [] , False : [] }
for arg in cls.arguments:
  d[arg == True].append(arg)

return d[True], d[False]

One potential problem here is that 'arg == True' may not be the same as 'if
arg:'. I couldn't come up with a better equivalent expression, maybe one of the
other readers knows more about this?
