Pickling - is the process whereby a Python object hierarchy is converted into a byte stream, and Unpickling - isthe inverse operation, whereby a byte stream is converted back into an object hierarchy. Pickling (and unpickling) is alternatively known as serialization, marshalling, or flattening. W...

The pickle and cPickle modules now automatically intern the strings used for attribute names, reducing memory usage of the objects resulting from unpickling. (Contributed by Jake McGuire; bpo-5084.) The cPickle module now special-cases dictionaries, nearly halving the time required to pickle them....
The pickled byte stream can be used to re-create the original object hierarchy by unpickling the stream. This whole process is similar to object serialization in Java or .Net. How does Python pickling work? When a byte stream is unpickled, the pickle module creates an instance of the ...
called "unpickling." A PKL file is pickled to save space when being stored or transferred over a network then is unpickled and loaded back into program memory during runtime. The PKL file is created using Python pickle and thedump()method and is loaded using Python pickle and theload()...
to chime in on languages - I've learned over the years that they're just tools in the toolbox - some better than others for certain problems - and therefore best to look at the problem first and decide if the language is suitable for needs over a given time frame. Python seems to b...
