The Cython language is a superset of the Python language that. C functions and declaring. C types on variables and class attributes. This allows the. compiler to generate very efficient C code from Cython code. The C code is generated once and then compiles with all major. CC compilers in CPython 2. Issuu is a digital publishing platform that makes it simple to publish magazines, catalogs, newspapers, books, and more online. Easily share your publications and get. There is possibly no more middleclass activity in the drab weeks after Twelfth Night than the menfolk of Islington, north London scouring the streets. About Cython. Cython is an optimising static compiler for both the Python programming language and the extended Cython programming language based on Pyrex. The most powerful, flexible, userfriendly wavefunction analysis program in quantum chemistry field. Amber is a package of programs for molecular dynamics simulations of proteins and nucleic acids. Cython 0. 2. 0. x as well as 3. We regularly run integration tests against all supported CPython versions and. Py. Py support is work in progress on both sides. Cython 0. 1. 7. The latest Py. Py version is always recommended here. All of this makes Cython the ideal language for wrapping. C libraries, embedding CPython into existing. C modules that speed up the. Python code. Documentation. External resources. If you still have questions, feel free to send an email to the. Aspects of the core development are discussed on the. If you are unsure which list to use, the cython users list is probably the right one to use, which has the larger audience. Cython is freely available under the open source. Apache License.

Google and Enthought funded Dag Seljebotn to greatly improve. Cython integration with Num. Py. Kurt Smith and Danilo Freitas were funded through the Google Summer of Code program to work on improved Fortran and C support respectively. Haoyu Bai was funded to work on Python 3 compatibility. Greg Ewing for inventing and developing Cythons predecessor. Useful Links. What users have to say about Cython You would expect a whole lot of organizations and people to fancy a. Python, yet almost as fast and. C. Add to that the ability to seamlessly integrate with both. C codebase and your Python codebase, easily mix very. Dun Peal on c. l. You guys rock In scikit learn, we have decided early on to do Cython, rather than C or. C. That decision has been a clear win because the code is way more. We have had to convince new contributors that Cython was. Python versions, was worth it. Gal VaroquauxThe biggest surprise and of course this is Cythons selling. Its exiciting to see that there are several active projects around. Python. The nice thing about Cython is that. C or maybe nearly the speed. C, 3 years from now it gives the real deal, O3 C, and it works. Fredrik JohanssonNot to mention that the generated C often makes use of. And. through all that, Cython code maintains a high level of integration. Python itself, right down to the stack trace and line numbers. Pay. Pal has certainly benefitted from their efforts through. Cython users like gevent, lxml, and Num. Py. While our. first go with Cython didnt stick in 2. Cython. Mahmoud Hashemi. Im honestly never going back to writing C again. Cython gives. me all the expressiveness of Python combined with all the performance. C. Ive been using it to. CC libraries, and its been an absolute amazing. Andrew TiptonA general rule of thumb is that your program spends 8. Thus a good strategy for efficient. Pythons profilers are great, and Cython allows. Hoyt KoepkeThe question was, in auto generated code, to what extent there. The. first time I did this, I got lots and lots of warnings from the tool for. SWIG and Cython. Basically, everything I found Cython emitting was a false positive and. CPy. Checker. Basically, Cython is about 7x times faster than Boost. Python, which. astonished me. Using Cython allows you to just put effort into speeding up the. This is vastly different from ditching all the code. It also requires you to learn. You also get to keep the niceness of. Python syntax which may Python coders have come to. If you have a piece of Python that you need to run fast, then I. Cython immediately. This means that I can. Python and the speed of C together, and thats a. StavrosFrom 8. 5 seconds at the beginning of this post down to 0. Writing a full on CPython module from scratch would probably. Cython if you know the quirks and are. But to someone who doesnt already drip CPython C. Cython is a godsend. Ultimately, theres 5 commonly used ways CPython C API. Boost Python, SWIG, Cython, ctypes to integrate C into Python, and. Cython a shot, if thats your. Its very easy to learn for anyone familiar with both C and. What I loved about the Cython code is that I use a Python. Vortex objects. This shows that we can use the. Python containers to manage objects. This is extremely. Clearly, if you are building code from scratch and need speed. Cython is an excellent option. For this I really must congratulate the. Cython and Pyrex developers. Prabhu RamachandranI wrote a script that compute a distance matrix O2 in. Python with Numpy arrays and the same script in Cython. It took me 1. 0. minutes to figure it out how Cython works and I gained a speed up of. Amazing. kfrancoiI would like to report on a successful Cython project. Successful in the sense that it was much faster than all code written. Also, the code is shorter and much easier. Making it this fast short readable maintainable. Cython. Alex van HoutenAt work, weve started using Cython with excellent success. We rewrote one particular Perl script as Cython and achieved a 6. As a Perl lover, this was impressive. We still. get all the benefits of Python such as rapid development and clean. C. Wim KerkhoffThe reason that I was interested in Cython was the long. I encountered while doing a multi variable. By simply. replacing the class that contained the differential equation with a. Cython version the calculation time dropped by a factor 5. Not bad. for half a Sunday afternoons work. KorbininI was surprised how simple it was to get it working both. Windows and Linux. I did not have to mess with make files or. Cython integrated well with Num. Py and Sci. Py. This expands the programming tasks you can do with Python. Sami BadawiThis is why the Scipy folks keep harping about Cython its. Python. Their user base has tons of legacy code. Python has had such a great adoption curve in that space is. Numpy has made the data portion of that interface easy. Cython makes the code portion quite painless, as well. Peter Z.
