public class PythonScriptExecutor
extends AbstractScriptExecutor

Deprecated, for removal: This API element is subject to removal in a future version.

in favor of PolyglotScriptExecutor with a python language argument.

A ScriptExecutor that implements special handling required for Python to emulate behavior similar to other JSR223 scripting languages.

Script evaluation using the Jython implementation results in a null return value for normal variable expressions such as x=2. As a work around, it is necessary to get the value of 'x' explicitly following the script evaluation. This class performs simple parsing on the last line of the script to obtain the variable name, if any, and return its value.
