<p style="color: grey"> Python recipe 579004 by <a href="/recipes/users/4173351/">Vasudev Ram</a> (<a href="/recipes/tags/database/">database</a>, <a href="/recipes/tags/pdf/">pdf</a>, <a href="/recipes/tags/pydal/">pydal</a>, <a href="/recipes/tags/python/">python</a>, <a href="/recipes/tags/python_developer_tools/">python_developer_tools</a>, <a href="/recipes/tags/sql/">sql</a>, <a href="/recipes/tags/web2py/">web2py</a>, <a href="/recipes/tags/xtopdf/">xtopdf</a>). </p> <p>This recipe shows how to use the PyDAL database library for Python, together with xtopdf, a PDF creation library for Python, to publish database data to PDF. PyDAL was earlier a part of the web2py Python web framework, and then was split out into a separate library that does not need to be used with web2py. It supports access to many popular relational databases, both open source and proprietary.</p>

<p style="color: grey"> Python recipe 577797 by <a href="/recipes/users/4178543/">Dominic Innocent</a> (<a href="/recipes/tags/vpython/">vpython</a>). </p> <p>Getting Vpython to run 2 moving objects is tricky as it tends to focus on only one. The answer I have used is to 'Flip-Flop' between the 2 blocks of code running each object; Set up 2 values for the flip-flop K &amp; P. At the end of each nested 'While' P will be incramented (p=p+1). K is the remainder of P/2 (k=p%2). If k = 0 Flip! If k != 0 Flop!. I haven't got it to recognise a 'collision' event yet; &amp; that is very Frustrating!</p>

Revision 2. </p> <p>In Ruby, the <a href="http://ruby-doc.org/core/classes/Struct.html">Struct class</a> is a convenient way to create a hash-like object on the fly and use it for your nefarious purposes. PHP 5+ can be convinced to do this type of things as well, it just doesn't have it out of the box. Here is a simple class that implements iterator and allows you to populate the internal data structure similar to how Ruby's Struct works. Syntactic sugar? Probably.</p> <p>Note: I haven't bothered to implement the Ruby Struct API per se, Instead I just got something similar by implementing the Iterator interface and keeping things very PHP-like.</p>

<p style="color: grey"> Python recipe 117248 by <a href="/recipes/users/98141/">Thomas Heller</a> (<a href="/recipes/tags/sysadmin/">sysadmin</a>). Revision 5. </p> <p>Distutil's bdist_wininst installers offer uninstallation support for Python extensions, many developers however only distribute sources in zip or tar.gz format. The typical steps to install such a distribution are: - download the file - unpack with winzip into a temporary directory - open a command prompt and type 'python setup.py install' - remove the temporary directory</p> <p>This script unpacks a source distribution into a temporary directory, builds a windows installer on the fly, executes it, and cleans everything up afterward.</p>
