cythonize compiles Cython source files (.pyx) into C extension modules. Cython is a superset of Python that enables C-level performance through static typing and direct C API access.
The tool handles the full compilation pipeline: generating C code, compiling with a C compiler, and building importable Python modules.

-i, --inplace

Build extensions in place.

Build using temporary build directory.

Parallel compilation jobs.

Force recompilation.

Generate HTML annotation.

Use Python 3 syntax.

Set Cython directive.

Set compiler option.

Generate C++ code.

Requires C compiler installed. Platform-specific extensions not portable. Annotation helps identify Python-heavy code. Some Python features slower in Cython.

Cython evolved from Pyrex, created by Greg Ewing in 2002. The Cython fork by Robert Bradshaw and Stefan Behnel added Python compatibility and features. The cythonize command provides a convenient wrapper over the compilation process.
