What's wrong?

[kishkin]

Hello everyone!

I wanted to write python script with defined function. From that script
I wanted to call C module, which in it's turn call defined python
function. Sounds simple. But I've got some troubles in realization. I'm
beginner at python so it's normal, I think. :)

Here's the code. I'll apreciate if anyone can answer me what's wrong
here.

power.c:

#include "Python.h"

static PyObject *
power(PyObject *self, PyObject *args)
{
  PyObject *result, *temp;

  int num;

  if (PyArg_ParseTuple(args, "iO", &num, &temp))
  {
if (!PyCallable_Chack(temp))  //here's error, but I don't know
why...
{
  return NULL;
}
  }

  result = Py_BuildValue("i", num*num);

  PyEval_CallObject(temp, result);
  Py_DECREF(result);

  Py_INCREF(Py_None);
  retrun Py_None;
}

static struct PyMethodDef power_methods[] = {
   {"power", power, METH_VARARGS, "powering number"},
   {NULL, NULL, 0, NULL}
};

void initpower()
{
   (void) Py_InitModule("power", power_methods);
}

power.py:

import power

def sst(some):
print some

power.power(9, sst)

Re: What's wrong?

:)) Oа course it PyCallable_Check there!!! :)) And error is that
PyCallable_Check returned 0.

power.c compiles without errors.

error is here:
 ---
[EMAIL PROTECTED] 1]$ make -f makefile.power
gcc power.c -g -I/usr/local/include/python2.4 -fpic -shared -o power.so
[EMAIL PROTECTED] 1]$ python power.py
Exception exceptions.TypeError: 'argument list must be a tuple' in
'garbage collection' ignored
Fatal Python error: enexpected exception during garbage collection

Re: simple perl program in python gives errors

Of course Grant Edwards is right, but I thought that your programm is
something like this:


a += 20 * 14
print a


and I thought that this is your perl program:

$a += 20 * 14
print $a


Funny if Grant Edwards is right... :)
