    copied!<p>I've started to slowly dabble with the Python/C API and after much fiddling and finagling, I was able to build a spam.pyd file. </p> <p>However, I must be missing something with this process and was hoping that someone could point me in the right direction. I thought that once spam.pyd was created, I could call it from Python via import spam. Is this true?</p> <p>When I try this, I get the following trace:</p> <pre><code>Traceback (most recent call last): File "&lt; pyshell#25 &gt;", line 1, in &lt;module&gt; import spam UnicodeDecodeError: 'utf8' codec can't decode byte 0x89 in position 1: unexpected code byte </code></pre> <p>Any ideas as to what I am doing wrong? I am working with Python 3.1.2 on Windows XP. I compiled spam.c via the mingw32 compiler.</p> <p>Thanks for reading this!</p> <p>EDIT:</p> <p>Well, it looks like the problem was that I had written the C code in an editor that saved the file with ANSI encoding. Strangely, if I retyped the code in Notepad, and saved the file with UTF8 encoding, I would get compile time errors complaining about invalid characters. When I used the built-in IDLE editor, everything worked fine. I was just following the example from the Python tutorial <a href="http://docs.python.org/py3k/extending/extending.html#a-simple-example" rel="nofollow noreferrer">here</a>.</p> <p><strong>Is this an usual problem to have??</strong></p> <p>Here is all the code that was used if it helps any: <code></p> <pre><code>#include &lt; Python.h &gt; static PyObject *spam_system(PyObject *self, PyObject *args) { const char *command; int sts; if (!PyArg_ParseTuple(args, "s", &amp;command)) return NULL; sts = system(command); return Py_BuildValue("i", sts); } static PyMethodDef SpamMethods[] = { {"system", spam_system, METH_VARARGS, "Execute a shell command."}, {NULL, NULL, 0, NULL} }; static struct PyModuleDef spammodule = { PyModuleDef_HEAD_INIT, "spam", NULL, -1, SpamMethods }; PyMODINIT_FUNC PyInit_spam(void) { return PyModule_Create(&amp;spammodule); } </code></pre> <p></code></p>
