Yes, I understand. I just reply to OP question not searching the reason why
he wants to manage *variables* this way (he talk about dict, so I hope he
know that they can be used to map names to values).
So, this is not an advice, just technical ways related to the question as it
And yes, personnally i use dictionnaries for such purpose.
