Has Micropython been compared? CPython needs the GIL because of its
frequent twiddling of reference counts. Without the GIL, multi-threaded
CPython would have to acquire

Yeah, that's tiny bug, however it is not the main problem...

Hi,
I have a framework written in C and I need to call Python from that framework.
I have written the code, and it runs fine, however when I recompile with OpenMP
enabled, I get segmentation faults and some times an error message:
Fatal Python error: GC object already tracked

I actually find Python for .NET most convenient

I did not try py2exe with these applications, so I cannot comment.

There is IronPython which compiles to .NET. And there was another project
bridging the .NET runtime with the standard Python interpreter of which I
forgot the name.

I use python for .NET in some applications... I've always used it for
using c# code from python (but i had some problems using it with py2exe
and win2000). I'll try using it the other way (c# calling python).
I also thought about trying ironpython, but it's too young for my work
projects...

Writing COM Servers is not hard

IronPython is the other way.
Choose COM Server approach if you are using the a lot of standard

Definitely choose this approach if y
Hi everybody,
I need write an application in c#, but i wnat to use some functions
that i have already written in python. Is there an "easy" way to call
my python code from c#? I must use COM or there are other ways? And, if
COM is the only way, where can i find some tutorials or examples? I've

I'm running into a problem when trying to perform a callback to a Python
function from a C extension. Specifically, the callback is being made by
a pthread that seems to cause the problem. If I call the callback from
the parent process, it works fine. The PyObject is static, and holds the
