Access to particular key value in variable output of Gurobi

[sami]

Hi,

I have sorted values and keys of my variables from Gorubi. for example, I have: [ 4.0, 3.0, 1.0 ] vars with[ (3, 1, 45), (2, 1, 80), (3, 1, 37) ]keys. If I choose 3.0 in vars, how can I access to (2,1,80) in keys? 

Regards,

Sami

If you had the numerical values themselves stored in a dictionary, say 'vals', then you would access the value using the key as an index. For example, vals[2, 1, 80]. For more details about fundamental Python data structures see https://docs.python.org/3/tutorial/datastructures.html.

If you had the variables (or Var objects) stored in a dictionary, say 'vars', then you would index the variable using the key and access the value through the X attribute (see http://www.gurobi.com/documentation/7.0/refman/x.html#attr:X). For example, vars[2, 1, 80].X

There are several code examples at http://www.gurobi.com/resources/examples/example-models-overview that should provide a great starting point for what you are trying to do.
