How to convert PyObject to java boolean type

问题

I would like to cast org.python.core.PyObject to java.lang.Boolean. Something similar to:

boolean i = ((Boolean) PyObject).booleanValue(); 

回答1:

Just try the following:

PyObject obj = interpreter.eval("True");
boolean i = ((PyInteger) obj).asInt() != 0;

回答2:

You should use the Python standard object interface nonzero method:

PyObject obj = interpreter.eval("True");
boolean i = obj.__nonzero__();

(it's called "nonzero" because it existed before Python had a boolean type and Guido's ways are mysterious sometimes)
