Var.index


Var.index

index

This property returns the current index, or order, of the variable in the underlying constraint matrix.

Return value:

-2: removed, -1: not in model, otherwise: index of the variable in the model

Note that the index of a variable may change after subsequent model modifications.

Example usage:

  v = model.getVars()[0]
  print(v.index) # Index will be 0
