Pickle allows you to save an entire data structure (such as an object) to disk as a binary file in a effortless (and fairly efficient) manner. For example, in my latest project I have created a Monte Carlo simulation that can take quite a bit of time to run. I also need to make multiple runs to get statistics on the results. At the end of each run, I need to dump the resulting data to disk so that it can be read in later by an analysis program. If I had to write data in a format that could be interchanged with other scientific software, I&rsquo;d use the <a href="http://hdf.ncsa.uiuc.edu/HDF5/">hdf5</a> format with the <a href="http://%3C%3Cwww.pytables.org/moin&amp;gt%3E;">pytables</a> package. However, right now I just need to get something working, and the pickle module is perfect. Here is how I save an object called box:</p>
