279 The Cython language makes writing C extensions for the Python language as
280 easy as Python itself. Cython is a source code translator based on the
281 well-known Pyrex_, but supports more cutting edge functionality and
284 The Cython language is very close to the Python language (and most Python
285 code is also valid Cython code), but Cython additionally supports calling C
286 functions and declaring C types on variables and class attributes. This
287 allows the compiler to generate very efficient C code from Cython code.
289 This makes Cython the ideal language for writing glue code for external C
290 libraries, and for fast C modules that speed up the execution of Python
