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