from the ``.pyx`` file, then manually compiling the ``.c`` file into a shared
object library or DLL suitable for import from Python.
(These manual steps are mostly for debugging and experimentation.)
- Use the [IPython]_ notebook or the [Sage]_ notebook,
- Use the [Jupyter]_ notebook or the [Sage]_ notebook,
both of which allow Cython code inline.
Currently, distutils is the most common way Cython files are built and distributed. The other methods are described in more detail in the :ref:`compilation` section of the reference manual.
