Logger module in python

[smilesonisamal]

Hi,
I am a newbie in python. I am looking for a existing module which I can import in my program to log the objects to a file?

I know there is a module Data:umper in perl which dumps the objects to file. But not sure about python.

Can anybody help me in this regard?

Regards
Pradeep

That's not what the OP wants.

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.

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:umper.

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
