selection of multiple properties, code help?

I am trying to modify some sound object properties on the fly, so I can hear the differences as I make changes. I know the changes will be updated without restarting the script, because I can make this work with presets.

I want to be able to select the property I want to change from a list and then use an input value to update the property.

Code:

def modifySettings(gr):

        settings = ['Environment','EnvSize','EnvDiffusion','RoomHF','RoomLF','DecayTime','DecayHFRatio','DecayLFRatio',

'Reflections','ReflectionsDelay','ReflectionsPan','Reverb','ReverbDelay','ReverbPan','EchoTime','EchoDepth',

'ModulationTime','ModulationDepth','AirAbsorptionHF','HFReference','LFReference','RoomRolloffFactor','Flags']

        select = viz.choose('Modify which setting?',settings)

        set = viz.input('Set '+settings[select]+' to')

        if settings[select] == 'Environment':

                gr.Environment = set

(twenty more elifs...)

        else:

                print 'I cannot change that setting'

Basically, I don't want to write a bunch of if statements unless I have to, so is there a simple way of doing this? Something that would be kind of like:

Code:

gr.settings[select] = set

There are a few ways to accomplish this. If all the choice strings exactly match the attribute name on the gr object, then you can use the following code:

Code:

def modifySettings(gr):

        settings = ['Environment','EnvSize','EnvDiffusion','RoomHF','RoomLF','DecayTime','DecayHFRatio','DecayLFRatio',

'Reflections','ReflectionsDelay','ReflectionsPan','Reverb','ReverbDelay','ReverbPan','EchoTime','EchoDepth',

'ModulationTime','ModulationDepth','AirAbsorptionHF','HFReference','LFReference','RoomRolloffFactor','Flags']

        name = settings[viz.choose('Modify which setting?',settings)]

        value = viz.input('Set '+name+' to')

        setattr(gr,name,value)

Sweet. Worked like a charm. Thanks!
