But not sure about python. Assuming you are looking for a serialization format: If efficiency, easily-at-hand, standard are important then pickle better than json better than yaml If however readability of the output (as the word 'log' suggests) is desired its the other way round: yaml is the most readable, pickle is utterly unreadable -- https://mail.python.org/mailman/listinfo/python-list

But not sure about python. You're talking about what's known as serializing an object. Taking the in-memory representation and turning it into something that can be written into a network connection or into a file, then read back in, and turned back into an in-memory object. The standard way to do this in Python is pickle (http://docs.python.org/2/library/pickle.html). Depending on the type of data you have, you might want to use JSON encoding instead (http://docs.python.org/2/library/json.html), but pickle is probably the most similar to Data::Dumper. -- https://mail.python.org/mailman/listinfo/python-list

Pradeep, if you want to dump data for debugging take a look at the pprint module; for example: http://docs.python.org/3.3/library/pprint.html If you want to store Python objects in files and read them later, most people seem to use pickle for that: http://docs.python.org/3.3/library/pickle.html Others translate into another format.
