Ok, so a better pattern for this would be to have a field of type PyCode and store the compiled version. Here is some pseudocode minus error handling:

[code]class MyScriptRunner {  
String scriptCode;  
PyCode compiledScript;

public void runIt() {  
if (compiledScript == null){  
compiledScript = Py.compile\_flags(scriptCode,  
“”,  
CompileMode.exec,  
CompilerFlags.getCompilerFlags());  
}  
ScriptManager manager = …  
PyStringMap locals = manager.createLocalsMap();  
manager.runCode(compiledScript, locals);  
}  
}[/code]
