Constr.index


Constr.index

index

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

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

Return value:

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

Example usage:

  c = model.getConstrs()[0]
  print(c.index) # Index will be 0
