    <p>Yes you can use the imports from the other file by going a.os.</p> <p>However, the pythonic way is to just import the exact modules you need without making a chain out of it (which can lead to circular references).</p> <p>When you import a module, the code is compiled and inserted into a dictionary of names -> module objects. The dictionary is located at sys.modules.</p> <pre><code>import sys sys.modules &gt;&gt;&gt; pprint.pprint(sys.modules) {'UserDict': &lt;module 'UserDict' from 'C:\python26\lib\UserDict.pyc'&gt;, '__builtin__': &lt;module '__builtin__' (built-in)&gt;, '__main__': &lt;module '__main__' (built-in)&gt;, '_abcoll': &lt;module '_abcoll' from 'C:\python26\lib\_abcoll.pyc'&gt;, # the rest omitted for brevity </code></pre> <p>When you try to import the module again, Python will check the dictionary to see if its already there. If it is, it will return the already compiled module object to you. Otherwise, it will compile the code, and insert it in sys.modules.</p> <p>Since dictionaries are implemented as hash tables, this lookup is very quick and takes up negligible time compared to the risk of creating circular references.</p> <blockquote> <p>Edit: I'm not worried about the import times, my problem is the visual clutter that the block of imports puts on the files.</p> </blockquote> <p>If you only have about 4 or 5 imports like that, its not too cluttery. Remember, "Explicit is better than implicit". However if it really bothers you that much, do this:</p> <pre><code>&lt;importheaders.py&gt; from django.utils import simplejson from google.appengine.ext import webapp from google.appengine.ext.webapp import template from google.appengine.ext import db &lt;mycontroller.py&gt; from importheaders import * </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
