copied!<p>You may want to explore the notion of <a href="http://docs.python.org/reference/datamodel.html" rel="noreferrer">namespaces</a>. In Python, the <a href="http://docs.python.org/tutorial/modules.html" rel="noreferrer">module</a> is the natural place for <em>global</em> data:</p> <blockquote> <p>Each module has its own private symbol table, which is used as the global symbol table by all functions defined in the module. Thus, the author of a module can use global variables in the module without worrying about accidental clashes with a user’s global variables. On the other hand, if you know what you are doing you can touch a module’s global variables with the same notation used to refer to its functions, <code>modname.itemname</code>.</p> </blockquote> <p>A specific use of global-in-a-module is described here - <a href="http://effbot.org/pyfaq/how-do-i-share-global-variables-across-modules.htm" rel="noreferrer">how-do-i-share-global-variables-across-modules</a>, and for completeness the contents are shared here:</p> <blockquote> <p>The canonical way to share information across modules within a single program is to create a special configuration module (often called config or cfg). Just import the configuration module in all modules of your application; the module then becomes available as a global name. Because there is only one instance of each module, any changes made to the module object get reflected everywhere. For example:</p> <p>File: config.py</p> </blockquote> <pre><code>x = 0 # Default value of the 'x' configuration setting </code></pre> <blockquote> <p>File: mod.py</p> </blockquote> <pre><code>import config config.x = 1 </code></pre> <blockquote> <p>File: main.py</p> </blockquote> <pre><code>import config import mod print config.x </code></pre>
