copied!<p>In python, it is a common practice to have a bunch of modules that implement various functions and then have one single module that is the point-of-access to all the functions. This is basically the <a href="http://en.wikipedia.org/wiki/Facade_Pattern" rel="nofollow noreferrer">facade pattern</a>.</p> <p>An example: say you're writing a package <code>foo</code>, which includes the <code>bar</code>, <code>baz</code>, and <code>moo</code> modules.</p> <pre><code>~/project/foo ~/project/foo/__init__.py ~/project/foo/bar.py ~/project/foo/baz.py ~/project/foo/moo.py ~/project/foo/config.py </code></pre> <p>What you would usually do is write <code>__init__.py</code> like this:</p> <pre><code>from foo.bar import func1, func2 from foo.baz import func3, constant1 from foo.moo import func1 as moofunc1 from foo.config import * </code></pre> <p>Now, when you want to use the functions you just do</p> <pre><code>import foo foo.func1() print foo.constant1 # assuming config defines a config1 variable print foo.config1 </code></pre> <hr> <p>If you wanted, you could arrange your code so that you only need to write</p> <pre><code>import foo </code></pre> <p>At the top of every module, and then access everything through <code>foo</code> (which you should probably name "globals" or something to that effect). If you don't like namespaces, you could even do</p> <pre><code>from foo import * </code></pre> <p>and have everything as global, but this is really not recommended. Remember: namespaces are one honking great idea!</p>
