The isLicensed method is an optional method that can be used to check if a script tool is licensed to execute. It can be used to restrict the tool from being run if the appropriate licenses and extensions required to run other geoprocessing tools used by the script tool are not available.
Si el método isLicensed devuelve False, la herramienta no se puede ejecutar. Si el método devuelve True o el método no se utiliza, la herramienta se puede ejecutar.
