Python newbie trying to embed in C++

[Marwan]

Hello all,

I'm new to Python and just starting to learn it. For he needs of my 
project, I need to call some specific methods in Python scripts from C++.


For now, I just compiled the example in the Python documentation about 
Pure Embedding to try it out ( 
http://docs.python.org/2/extending/embedding.html#pure-embedding ).


I'm trying to test it on an extremely simple script called test.py which 
contains the following:


def testPY( value ):
   print('You input ', value )

 def Hello():
print('Hello')


When I run the generated exe, I get errors about the functions not 
existing...


TestPython.exe test Hello
AttributeError: 'module' object has no attribute 'Hello'
Cannot find function "Hello"


My Python version is 2.7.3 because that's the version used in the module 
we need to access. And I'm using VS2010 SP1 for compiling my C++ because 
that's the version used to generate our DLLs and EXEs.


Could anyone tell me why this is happening?

And I'd appreciate it if you could give me pointers to how to easily 
call Python from C++.


Thanks in advance for your help,

Marwan

"test" is the name of a module in the standard library.  My guess
would be that for some reason it's importing that module rather than
your test.py.  Make sure that test.py can be found on your sys.path,
and perhaps change the name of your module to reduce confusion.

I just noticed that my reply went to the message sender and not to the 
newsgroup, so I'm posting again: thanks, that was it. Just renaming my 
test.py file solved the problem.

Maybe you can use boost::python?

http://www.boost.org/doc/libs/1_53_0/libs/python/doc/

Cave: I haven't used it and don't know if it is up-to-date.
