Currently with pickle you have to "open" the file separately from the
pickle operation, generally using a "with" clause, then provide the file
object to one of the pickle.dump or pickle.load. This adds quite a bit of
boilerplate for simply saving a file
I think it would be nice if pickle.dump and pickle.load would also accept a
filename or path. The functions would automatically open the file in the
correct way, save/load the object, then close the file. This would reduce
the amount of code needed to save a single object by at least half, and
would eliminate the incentive to use unsafe (I think?) approaches like
opening within the dump or load, which the wiki still recommends [1].
So something like:
with open('myfile.p', 'wb') as f:
pickle.dump(myobj, f)
Would be:
pickle.dump(myobj, 'myfile.p')
Sorry if this has already been discussed, but I searched the mailing list
history and couldn't find it.
