Writing Extensions for Python 3 in C

0 votes
37 views

I have searched for lots of tutorials and documentation on the web but, didnt find a decent one to develop extensions for Python 3 using a custom compiler (mingw32, nvcc). Please help me. PS: Dont point me to Python Documentation. It is not good for beginners. It doesnt elaborate about calls and implementation.

There is even a tutorial here:

http://docs.python.org/3/extending/index.html

Have you tried that yet? Doing it with a different compiler is something I would save for a second step. Maybe if you described your problems with a bit more detail would help.

You need to tell what youve read, what youve tried, where stuck. Yes the extending and embedding stuff http://docs.python.org/2/extending/ and
http://docs.python.org/2/c-api/index.html is more difficult than much other than other python docs.

That is intrinsic to the problem -- you are not in the python world but the C world and C is a much harder and headachey-er than python. And building the python infrastructure on top of that is still harder.

If you have to use it, you really need to get the data-structure invariants right: eg http://docs.python.org/2/c-api/intro.html#objects-types-and-reference-counts.

However as Terry suggests, using something like Cython to avoid this should always be first explored. Heres a list

  1. 'Classic' extending/embedding
  2. SCXX
  3. PyCXX
  4. Boost
  5. Ctypes
  6. Swig
  7. Sip
  8. cython

Explore in reverse order!

I understand there have been changes to the way that extensions are supposed to be built for windows. Is there any user documentation regarding these changes?

Last time I looked the appropriate Visual Studio hadn't been release so I guess I will need to use my MSDN skills (or incantations) to first get that installed.

For example:

a=[-15,-30,-10,1,3,5]

I want to find a negative and a positive minimum.

example: negative
print(min(a)) = -30

positive
print(min(a)) = 1
