I am learning how to extend Pythong with C++. I have will be writing
some code in C++ and want/need Python to interact with it. I am not
having success following the online documentation from
http://docs.python.org/ext/ext.html. I have also looked briefly at
some of the demos in the source code
Oops, sorry. My question is, how can I know if my Python interpreter
was lined by C++? The non-specific questions are, of course, does
anyone have any hints or suggestions? Good websites to visit?
Thanks,
Jeremy

Unfortunately, I need to know a bit more than just the concept 'extern
"C"'. I am really slow at this. Can anyone point me towards some
examples or a tutorial (other than the one from python.org, I didn't
understand that one)?
Thanks,
Jeremy

I have written a simple C++ program in my efforts to learn how to
extend Python. It is shown below. Everything compiles and installs
correctly, but I get strange answers. I know the function "Pi" is
correct because when I call it from a C++ code it gives the correct
answers. This is what I get
Well what do you know, that worked! It's one of those errors that you
can't see yourself, but someone else can see it instantly.

I am extending python with C++ and need some help. I would like to
convert a string to a mathematical function and then make this a C++
function. My C++ code would then refer to this function to calculate
what it needs. For example I want to tell my function to calculate
"x^2 + 3x +2", but later
I was unaware of the exec and eval functions in Python. Without trying
them, they seem to be what I want to do. I'll play around with it and
see if I can figure it out. Thanks for the suggestions everyone.

I am trying to learn how to extend and/or embed Python. I have looked
at the document "Extending and Embedding the Python Interpreter" and
also "Python/C API Reference Manual. In the examples shown in
"Extending..." there are some things I ma not familiar with so I turn
to the index in the Refere
I have the following in my code
a = (1,2,3)
print "a = %s" %a
But when I run this, I get:
TypeError: not all arguments converted during string formatting
Now I realize why this happens, a is actually 3 elements when the print
statement is only expecting to print one value. I tried
print "a =

I am writing a class that is intended to be subclassed. What is the
proper way to indicate that a sub class must override a method?

My Python script makes a bunch of images that I want to use as frames
in a movie. I've tried searching for a module that will take these
images and put them together in a Quicktime or mpeg movie, but haven't
found anything. My images are currently pdfs, but I could make them
into just about anyth

I have created a class that inherits from the list object. I want to
override the append function to allow my class to append several
copies at the same time with one function call. I want to do
something like:
import copy
class MyList(list):
__init__(self):
pass
def append(self, ob

I am subclassing the array class and have __new__ to initialize and
create my class. In that class I create not only do I create an array
object, but I also create some other data in __new__ I want to have
access to outside of __new__. I tried
self.mydata = mydata
but that didn't work.
Can som
Please excuse me if this is obvious to others, but I can't figure it
out. I am subclassing dict, but want to prevent direct changing of
some key/value pairs. For this I thought I should override the
__setitem__ method as such:
class xs(dict):
"""
XS is a container object to hold informa

I am using distutils to comiple/install a c extension created with
SWIG. However I need to be able to specify the output filename from
gcc. I tried doing this with the "extra_compile_args" and
"extra_link_args" by setting them equal to "-o MyOutputName.so" but
that didn't work. Can someone show
Hello all,
I am using distutils for building/compiling my Python extensions. The
default configuration tells the compiler to generate debug information
with the "-g" flag. I don't want this, but I can't seem to figure out
how to get rid of it. Does anyone now how?
Thanks,
Jeremy
