| Hans-G?nter@25169 | 1 Cython is an optimising static compiler for both the Python programming |
| Hans-G?nter@25169 | 2 language and the extended Cython programming language (based on Pyrex). |
| Hans-G?nter@25169 | 3 It makes writing C extensions for Python as easy as Python itself. |
| Hans-G?nter@25169 | 4 |
| Hans-G?nter@25169 | 5 Cython gives you the combined power of Python and C to let you |
| Hans-G?nter@25169 | 6 |
| Hans-G?nter@25169 | 7 - write Python code that calls back and forth from and to C or C++ code |
| Hans-G?nter@25169 | 8 natively at any point. |
| Hans-G?nter@25169 | 9 - easily tune readable Python code into plain C performance by adding |
| Hans-G?nter@25169 | 10 static type declarations, also in Python syntax. |
| Hans-G?nter@25169 | 11 - use combined source code level debugging to find bugs in your Python, |
| Hans-G?nter@25169 | 12 Cython and C code. |
| Hans-G?nter@25169 | 13 - interact efficiently with large data sets, e.g. using multi-dimensional |
| Hans-G?nter@25169 | 14 NumPy arrays. |
| Hans-G?nter@25169 | 15 - quickly build your applications within the large, mature and widely |
| Hans-G?nter@25169 | 16 used CPython ecosystem. |
| Hans-G?nter@25169 | 17 - integrate natively with existing code and data from legacy, low-level |
| Hans-G?nter@25169 | 18 or high-performance libraries and applications. |
| Hans-G?nter@25169 | 19 |
| Hans-G?nter@25169 | 20 The Cython language is a superset of the Python language that additionally |
| Hans-G?nter@25169 | 21 supports calling C functions and declaring C types on variables and class |
| Hans-G?nter@25169 | 22 attributes. This allows the compiler to generate very efficient C code |
| Hans-G?nter@25169 | 23 from Cython code. |
| Hans-G?nter@25169 | 24 The C code is generated once and then compiles with all major C/C++ |
| Hans-G?nter@25169 | 25 compilers in CPython 2.6, 2.7 (2.4+ with Cython 0.20.x) as well as 3.3 |
| Hans-G?nter@25169 | 26 and all later versions. |
| Hans-G?nter@25169 | 27 We regularly run integration tests against all supported CPython versions |
| Hans-G?nter@25169 | 28 and their latest in-development branches to make sure that the generated |
| Hans-G?nter@25169 | 29 code stays widely compatible and well adapted to each version. |
| Hans-G?nter@25169 | 30 PyPy support is work in progress (on both sides) and is considered mostly |
| Hans-G?nter@25169 | 31 usable since Cython 0.17. The latest PyPy version is always recommended here. |
| Hans-G?nter@25169 | 32 |
| Hans-G?nter@25169 | 33 All of this makes Cython the ideal language for wrapping external C libraries, |
| Hans-G?nter@25169 | 34 embedding CPython into existing applications, and for fast C modules that |
| Hans-G?nter@25169 | 35 speed up the execution of Python code. |
