To go beyond that, Cython provides language constructs to add static typing
and cythonic functionalities to a Python module to make it run much faster
when compiled, while still allowing it to be interpreted.

projects would commonly decide on a specific way to keep the static type
information easy to manage.
Although it is not typically recommended over writing straight Cython code
in a :file:`.pyx` file, there are legitimate reasons to do this - easier
testing
, collaboration with pure Python developers, etc. In pure mode, you
are more or less restricted to code that can be expressed (or at least
emulated) in Python, plus static type declarations. Anything beyond that
can only be done in .pyx files with extended language syntax, because it
depends on features of the Cython compiler.
