It includes some poor mans circular dependency detection (very poor mans).</p>

Here are a few examples and conveniences that many newcomers, even a few seasoned developers, are unaware.</p>

Revision 3. </p> <p>Small module to and check for differences between 2 DB.</p> <p>It will compare the table list, the tables structure and their content.</p> <p>When you run the program, you are ask if you want a detailed comparison. As global comparison will list all the different tables, detailed comparison will output every different record (and will take longer to run)</p>

Revision 2. </p> <p>compare() takes a function parameter and returns a callable comparator when compared to a value. When called, the comparator returns result of comparing the result of calling the function and the value it was created with.</p> <p>Basic usage:</p> <pre class="prettyprint"><code>items = [1, 2, 3, 4, 5] def double(x): return x * 2 for i in filter(compare(double) &gt; 5, items): print i #Prints 3, 4 and 5 </code></pre>

Revision 2. </p> <p>my_list.index(element) returns the index of the element using common comparision (as in == or __eq__() or __cmp__()). If you need to find an element on the list using identity comparing (is) then this function can do it for you</p>
