error

[Guest]

Hi,

Today is my first day of working on python. I want to execute python
script through C++ program. I found one very good article with example
at http://docs.python.org/ext/pure-embedding.html.
I followed the procedure as given, the code is compiled but while
running it is giving error like:
ImportError: No module named multiply
Failed to load "multiply"

Here are the steps I followed, please suggest where I am wrong and how
can I remove the above error.

Step 1: Copied the given C program into a file called test.cpp (using vi
editor)
Step 2: Compiled it using : g++ test.cpp /usr/lib/libpython2.4.so
(created a.out)
Step 3: Wrote the given script of multipication in a file named as
multiply (using vi editor)
Step 4: But while running the program using : ./a.out multiply
multiply 3 2
Getting this error: ImportError: No
module named multiply
Failed to
load "multiply"

Please help me out.

Thanks & Regards,

The name of module should be multiply.py

Try naming your source file multiply.py but continue to use the module
name (multiply) in the command line. [Note: you could have a binary
extension module called multiply in a binary file called multiply.so]

I guess the author of that manual section didn't contemplate somebody
on their first day with Python doing some embedding :-)

HTH,
John

Ooops... sorry.
I meant name of python source file, of course.
