Just to avoid confusion, that's false.

interp.exec takes the same arg "as" the exec statement:

http://www.python.org/doc/current/ref/exec.html

e.g. the following example works for me:


import org.python.util.* ;

public class interp {

  public static void main(String[] args) {

  	PythonInterpreter interp = new PythonInterpreter();
  	
  	String x = "a,b=1,1\nif a:\n print 3\nif b:\n print 5";
  	
  	interp.exec(x);
  }


}


Clearly one should pay attention to indentation.
Passing chunks of code, e.g. incomplete compound statements does not work, OTOH.
