# RandomNumberGenerator

## Resumen

Determines the type and seed that will be used to create random numbers.

## Debate

arcgis.rand() ya no se admite desde ArcGIS Pro 2.0. La función arcgis.rand() se usaba principalmente para permitir la creación de valores aleatorios con las herramientas Calcular valor y Calcular campo, la configuración del entorno Generador de números aleatorios y la función CreateRandomValueGenerator. En su lugar, se deben usar otras funciones similares del módulo random de Python.

## Descripción general del método

 Método Explicación exportToString () Exports the object to its string representation. loadFromString (string) Restore or update the spatial reference object using a WKT string. The exportToString method can be used to export a WKT string representation of the spatial reference.Using a WKT string with a horizontal coordinate system.``````# The following string is the WKT for the # Geographic Coordinate system "WGS 1984" (factory code=4326) wkt = 'GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],\ PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]];\ -400 -400 1000000000;-100000 10000;-100000 10000;8.98315284119522E-09;\ 0.001;0.001;IsHighPrecision' sr = arcpy.SpatialReference() sr.loadFromString(wkt)``````Using a WKT string with a horizontal and vertical coordinate system. Note that the vertical coordinate system is defined in the VERTCS section of the WKT.``````# The following string is the WKT for the # Geographic Coordinate system "WGS 1984" (factory code=4326), # with a vertical coordinate system "WGS 1984" (factory code=115700) wkt = 'GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],\ PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],\ VERTCS["WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],\ PARAMETER["Vertical_Shift",0.0],PARAMETER["Direction",1.0],UNIT["Meter",1.0]];\ -400 -400 1000000000;-100000 10000;-100000 10000;8.98315284119522E-09;\ 0.001;0.001;IsHighPrecision' sr = arcpy.SpatialReference() sr.loadFromString(wkt)``````
