Key actions include adding terms or expressions using `AddTerm` and `AddExpression`. You can construct expressions from `BoolVar`, `IntVar`, or constants. `Sum` and `WeightedSum` methods enable creating expressions from lists of variables. The class provides access to coefficients via `coefficients`, variable indices via `variables`, and the constant term via `constant`. It also determines if an expression has variables with `IsConstant`.\n"]]
