I found a Python class within an Open Source software.
I would like to use it in my own Python script.
I tried to import it, but I got following message.

Note this subtle distinction. A Python course will (theoretically, at

Hi,
Apologies if this was asked before, I couldn't find anything.
I have a class defined in a python file:
for example:
class demo:
[ class definition goes here]
I'm writing a C extension.
In the first function, I take an instance of the "demo" class and do
my magic. It's working, all is

You are right. I did not look at the PyCObject_* API close enough.
I thought of wrapping the CObject with a Python class, and calling the
destructor from __del__. That would be less reliable.
S.M.

cdef __dealloc__ in Cython). If the
pointer references a resource that needs to be closed, this is safer
than using a __del__ method in a Python class.

Hello
From my C extension module I want to store a C pointer in a given PyObject.
The only way I figure how to do it is to use Py_BuildValues and store the
poiner casted to Py_ssize_t, thus:
Py_BuildValues("n", (Py_ssize_t)my_ptr)
Can it be done differently?

Same directory as the script that's importing it, or in the PYTHONPATH.
import sys
print sys.path
I have a class that is defined in a file called MyClass.py
How do I use that class in another python script..
import MyClass ? (Does it need to be in a specific location?)
