Interpreting the JSON Solution

Once you have retrieved a JSON solution string, you can use a JSON parser to retrieve solution information for individual variables and constraints. This parser isn't included in the Gurobi library. Rather, programming languages have libraries for doing this. The appropriate package in Python is (not surprisingly) called json. The following provides a simple example of how this library can be used to parse a JSON solution string and extract a few pieces of solution information:

            # Get JSON solution as string, create dict from it
            sol = json.loads(batch.getJSONSolution())

            # Pretty printing the general solution information
            print(json.dumps(sol["SolutionInfo"], indent=4))
