The library is higher level and easier to use than the API, though for limited functionality of the API. It can be used to easily do basic access of Wikipedia pages, which could be useful for many educational, reference and other purposes. This recipe shows the basic use of the wikipedia library, by using it to search for information about oranges.</p> Give Python code a web plus command-line interface with hug (Python) 2017-01-05T16:57:15-08:00Vasudev Ramhttp://code.activestate.com/recipes/users/4173351/http://code.activestate.com/recipes/580742-give-python-code-a-web-plus-command-line-interface/ <p style="color: grey"> Python recipe 580742 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/cli/">cli</a>, <a href="/recipes/tags/commandline/">commandline</a>, <a href="/recipes/tags/hug/">hug</a>, <a href="/recipes/tags/library/">library</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/python3/">python3</a>, <a href="/recipes/tags/user_interface/">user_interface</a>, <a href="/recipes/tags/web/">web</a>, <a href="/recipes/tags/web_server/">web_server</a>). </p> <p>This recipe shows how to take a Python function and wrap it with both a web and a command-line interface, somewhat easily, using the hug Python library. The example used shows how to wrap a function that uses the psutil library to get information on disk partitions. So you can see the disk partition info either via the web browser or the command line. The code for the recipe is shown below. It is also possible to wrap multiple functions in the same Python file, and expose all of them via both the web and the command-line.</p> <p>More information and multiple sample outputs are available here:</p> <p><a href="https://jugad2.blogspot.in/2017/01/give-your-python-function-webcli-hug.html" rel="nofollow">https://jugad2.blogspot.in/2017/01/give-your-python-function-webcli-hug.html</a></p> gsl with python3 (Python) 2010-02-26T11:34:01-08:00David Lamberthttp://code.activestate.com/recipes/users/4167420/http://code.activestate.com/recipes/576549-gsl-with-python3/ <p style="color: grey"> Python recipe 576549 by <a href="/recipes/users/4167420/">David Lambert</a> (<a href="/recipes/tags/gnu/">gnu</a>, <a href="/recipes/tags/gsl/">gsl</a>, <a href="/recipes/tags/library/">library</a>, <a href="/recipes/tags/scientific/">scientific</a>). </p> <p>Some shared library functionality is accessible directly from python.

Many of the methods are overloaded to provide great versitility in what operations can be performed. To allow for even greater operations, the many methods mays be wrapped with the included <code>autocast</code> method so that even more datatypes can be used in whatever calculations the programmer may desire.</p> ActiveState recipe importer (Python) 2011-11-23T02:27:51-08:00nosklohttp://code.activestate.com/recipes/users/4166478/http://code.activestate.com/recipes/577958-activestate-recipe-importer/ <p style="color: grey"> Python recipe 577958 by <a href="/recipes/users/4166478/">nosklo</a> (<a href="/recipes/tags/activestate/">activestate</a>, <a href="/recipes/tags/code/">code</a>, <a href="/recipes/tags/import/">import</a>, <a href="/recipes/tags/library/">library</a>). </p> <p>Finally!
