I have a nested list of tuples defined in python, and I want to feed this to the .mod file of OPL. I am getting an error while doing so. Could you please refer to the below code snippet. Thanks 

from doopl.factory import *

// nested tuple list
test = [((1,2),"Q"),((3,4),"R")]

with create_opl_model(model="test.mod") as opl:
    opl.set_input("test", test)

    // followed by other code (excluding it for now)

// following is starting few lines of the .mod file


tuple tup1 {
   int a;
   int b;   
 }
  
tuple nested_tup {
   tup1 x;
   string y;
 }
 
{nested_tup} test = ...;

// excluding other parts of the file

Hi,

I am not sure that s supported yet.
So in the meantime you could transform your nested tupleset into a flat tuple set:

test = [((1,2),"Q"),((3,4),"R")]
test2=[ [i[0][0],i[0][1],i[1]] for i in test]

print(test2)​

which gives

[[1, 2, 'Q'], [3, 4, 'R']]​

and then you rely on the tuple set input for doopl

regards

PS: better doopl is already a wish in https://ibm-data-and-ai.ideas.aha.io/?project=CPLEX
