I'm working in an embedded Linux environment and I have some Python code which I would like to use. My Python code is just doing some math, not using any library other than Numpy and the common ones.
Is there any way to build up a library that I can call from C or C++ code?

To write Python modules in C, you'll need to use the Python API, which defines the various functions, macros, and variables that allow the Python interpreter to call your C code. All of these tools and more are collectively bundled in the Python. h header file.
Extending Python with C or C++ It is quite easy to add new built-in modules to Python, if you know how to program in C. Such extension modules can do two things that can't be done directly in Python: they can implement new built-in object types, and they can call C library functions and system calls.
Embedding the CPython interpreter into a C or C++ program is actually pretty straightforward.
The official documentation has some complete examples.
Also, check out SWIG and Boost.Python.
