Invoking a function on a module
by john.m.baker

Rate this Message:
Hello,
I’ve looked at the Python API docs but feel that a few common examples would be of use. For example, I can pass a String to PythonInterpreter and execute it, but how can I invoke the method ‘test’ on the module ‘mymodule.py’, which is in the classpath? Or even better, if my classpath contains a directory ‘mypackage’, and the module lives inside it, how do I do: import mypackage.mymodule mypackage.mymodule.test(‘params’)
through the Python API? Thanks, John

Hi,
If I want to do: Import mypackage.mymodule Mypackage.mymodule.mymethod('a', 123) Then how do I do it like this: PyModule module = ... ? PyObject result = module.invoke("mymethod", new PyObject[] { new PyString('a'), new PyInteger(123) } ) I don't know how to get a reference to module - the reason I ask is I'd like to implement this slightly more strictly than running PythonInterpreter.exec for each method call.

May I suggest the far easier mechanism of using an object factory? It's more general than the incomplete snippet presented, and we have lots of experience using it for Java integration:

Re: Invoking a function on a module

I also just updated the PythonInterpreter section of the book and sent to Apress. I will be updating the online book at some point in the not too distant future. For now, here is a table that I put together that describes all of the different methods available for use with the PythonInterpreter. Perhaps it will help you out a bit with the PythonInterpreter. However, I agree with Jim that object factories are the best way to go. Check out the PlyJy (http://kenai.com/projects/plyjy) project for some working examples.
Here is that table (unformatted and ugly): PythonInterpreter Methods Method Description setIn(PyObject) Set the Python object to use for the standard input stream setIn(java.io.Reader) Set a java.io.Reader to use for the standard input stream setIn(java.io.InputStream) Set a java.io.InputStream to use for the standard input stream setOut(PyObject) Set the Python object to use for the standard output stream setOut(java.io.Writer) Set the java.io.Writer to use for the standard output stream setOut(java,io.OutputStream) Set the java.io.OutputStream to use for the standard output stream setErr(PyObject) Set a Python error object to use for the standard error stream setErr(java.io.Writer Set a java.io.Writer to use for the standard error stream setErr(java.io.OutputStream) Set a java.io.OutputStream to use for the standard error stream eval(String) Evaluate a string as Python source and return the result eval(PyObject) Evaluate a Python code object and return the result exec(String) Execute a string of Python source in the local namespace exec(PyObject) Execute a Python code object in the local namespace execfile(String filename) Execute a file of Python source in the local namespace execfile(java.io.InputStream) Execute an input stream of Python source in the local namespace compile(String) Compile a string of Python source as an expression or module compile(script, filename) Compile a script of Python source as an expression or module set(String name, Object value) Set a variable of Object type in the local namespace set(String name, PyObject value) Set a varuable of PyObject type in the local namespace get(String) Get the value of a variable in the local namespace get(String name, Class<T> javaclass Get the value of a variable in the local namespace. The value will be returned as an instance of the given Java class. Hope this helps. juneau001@... http://jj-blogger.blogspot.com Twitter ID: javajuneau 2009/11/6 Alex Grönholm <alex.gronholm@...>
