something like this?

Thanks, it works great and it's faster...

I altered my script to avoid iterating the parameter list twice:

#input_ids = [_.NickName for _ in ghenv.Component.Params.Input]
#input_objs = [_.VolatileData for _ in ghenv.Component.Params.Input]
#case_dict = dict(zip(input_ids, input_objs))

case_dict = dict([(i.NickName, i.VolatileData) for i in ghenv.Component.Params.Input])

Good idea!

I improved it a little bit:

a = next((_.VolatileData for _ in ghenv.Component.Params.Input if _.NickName == x), [])

That only gets the desired data instead of building the hole dictionary.

Also set the inputs (1,2,3,...) to List Access.

Thanks, great ideas!

I also tried this, to avoid iterating through input parameters:

index = ghenv.Component.Params.IndexOfInputParam(x) #???
a = ghenv.Component.Params.Input[index].VolatileData

But it doesn't work. I get index = -1 for some values of x (eg. for x='4'), even though I shouldn't. Any idea why?

I'm not sure but probably IndexOfInputParam checks the Name instead of the NickName of the parameter.
