I have a detail integer attribute tuple with 4 entries. In another node I want to change the i-th element of that tuple. What's the best way to do this?

hi,

thanks a lot! But I have to be more specific. I don't know in advance which index of the parameter is going to change. So what I am looking for is more like a simple array assignemd. a = value. Also the 4-tuple is just an example what if I have an n-tuple? I guess my best bet is to use a simple python op.
