[BangPypers] Return values

[Vishal]

Dear Noufal,

Have not gone through all the replies...so may be i am repeating...may be I
am not in my senses :))

I would create a "stats_bundle" object, with members like stats_val
and stats_list,
which are initialized to None. So you always get a stats_bundle object
which you can pass around to the handler function in the calling code.
Since one of the above members is always going to be None, a simple check
in the handler will be fine..i guess.
But all this is stylistic...so it depends.

Take care,
Vishal


Thanks and best regards,
Vishal Sapre
