Cython started as a language designed to write extension modules, and has long become the most widely used static compiler for Python, bringing C and C++ data types into the language. Use it to talk to existing C/C++ code or to bring your Python code up to C speed.

Cython has come a long way from its beginnings as Pyrex in 2002 up to the latest stable major release: Cython 3.0. It started as a language designed to write extension modules, and it became the most widely used static compiler for Python, bringing C and C++ data types into the language.

This talk will present new features built into the language, from static C types in the modern Python typing syntax to automatic ufunc generation, that make writing lightning fast Python code easy and pythonic.
