Better writing in python

[Alexandre Badez]

Thanks for your try Cliff, I was very confused :P
More over I made some mistake when I post (to make it easiest).

Here is my real code:

with
dArguments = {
  'argName' : {
    'mandatory' : bool, # True or False
    [...], # other field we do not care here
  }
}

lMandatory = []
lOptional = []
for arg in cls.dArguments:
  if cls.dArguments[arg]['mandatory']:
    lMandatory.append(arg)
  else:
    lOptional.append(arg)
return (lMandatory, lOptional)

So, as you see, we agree each other about "if bool" or "if bool is
True" ;)

So, my question was how to give it a better 'python like' look ?
Any idea ?
