Python is widely used in academia +and scientific projects because it is easy to write, and it performs really well. + +Due to its high performance nature, scientific computing in python often refers to external libraries, typically +written in faster languages (like C, or FORTRAN for matrix operations). The main libraries used are NumPy and SciPy + +Libraries +::::::::: + +Numpy +----- +`NumPy `_ is a low level library written in C (and FORTRAN) for high level mathematical functions. +NumPy cleverly overcomes the problem of running slower algorithms on Python by using multidimensional arrays and functions that operate on arrays. +Any algorithm can then be expressed as a function on arrays, allowing the algorithms to be run quickly. + + +NumPy is part of the SciPy project, and is released as a separate library so people who only need the basic requirements can just use NumPy. + +NumPy is compatible with Python versions 2.4 through to 2.7.2 and 3.1+. + +SciPy +----- +`SciPy `_ is a library that uses Numpy for more mathematical function. SciPy uses NumPy arrays as its basic data structure. +SciPy comes with modules for various commonly used tasks in scientific programing like linear algebra, integration (calculus), +ordinary differential equation solvers and signal processing. + +Enthought +--------- + +Installing NumPy and SciPy can be a daunting task. Which is why the `Enthought Python distribution `_ was created. With Enthought, +scientific python has never been easier (one click to install about 100 scientific python packages). User beware: Enthought is not free. + +Matplotlib +---------- + +.. todo:: write about matplotlib. + +Resources +::::::::: + +Many people who do scientific computing are on Windows. And yet many of the scientific computing packages are notoriously difficult to build and install. +`Christoph Gohlke `_ however, has compiled a list of Windows binaries for many useful Python packages. +The list of packages has grown from a mainly scientific python resource to a more general list. It might be a good idea to check it out if you're on Windows. \ No newline at end of file diff --git a/docs/scenarios/web.rst b/docs/scenarios/web.rst index 8c41c84f7..67f240f4d 100644 --- a/docs/scenarios/web.rst +++ b/docs/scenarios/web.rst @@ -71,12 +71,23 @@ you may need, such as database access or form generation and validation.
