arcgis.rand() は、ArcGIS Pro 2.0 以降サポートされなくなりました。arcgis.rand() 関数は、[値の計算 (Calculate Value)] および [フィールドの計算 (Calculate Field)] ツール、[乱数ジェネレーター] 環境設定、CreateRandomValueGenerator 関数を使用したランダム値の作成を中心に使われてきました。代わりに、Python の random モジュールを使用する、同等の関数を使用する必要があります。

exportToString ()	Exports the object to its string representation.
