223 The Cython language makes writing C extensions for the Python language as
224 easy as Python itself. Cython is a source code translator based on the
225 well-known Pyrex_, but supports more cutting edge functionality and
228 The Cython language is very close to the Python language (and most Python
229 code is also valid Cython code), but Cython additionally supports calling C
230 functions and declaring C types on variables and class attributes. This
231 allows the compiler to generate very efficient C code from Cython code.
233 This makes Cython the ideal language for writing glue code for external C
234 libraries, and for fast C modules that speed up the execution of Python
