Revision 2. </p> <p>In most of the object oriented codes we write, we need to set class attributes to the given argument values and this is a very line-consuming thing. To get over these redundant lines, I found a solution using decorators. </p>

Revision 6. </p> <p>A Flipdict is a python dict subclass that maintains a one-to-one inverse mapping. Each key maps to a unique value, and each value maps back to that same key. Each instance has a "flip" attribute to access the inverse mapping.</p>
