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