What about *READING THAT FUCKING MANUAL* ? http://docs.python.org/lib/node316.html """ dump(obj, file[, protocol]) Write a pickled representation of obj to the open file object file. This is equivalent to Pickler(file, protocol).dump(obj). If the protocol parameter is omitted, protocol 0 is used. If protocol is specified as a negative value or HIGHEST_PROTOCOL, the highest protocol version will be used. Changed in version 2.3: Introduced the protocol parameter. file must have a write() method that accepts a single string argument. It can thus be a file object opened for writing, a StringIO object, or any other custom object that meets this interface. load(file) Read a string from the open file object file and interpret it as a pickle data stream, reconstructing and returning the original object hierarchy. This is equivalent to Unpickler(file).load(). file must have two methods, a read() method that takes an integer argument, and a readline() method that requires no arguments. Both methods should return a string. Thus file can be a file object opened for reading, a StringIO object, or any other custom object that meets this interface. This function automatically determines whether the data stream was written in binary mode or not. """ Example use: >>> d = dict(a=1, b=2) >>> f = open("mydict.dat", "w") >>> pickle.dump(d, f) >>> f.close() >>> f = open("mydict.dat") >>> d2 = pickle.load(f) >>> f.close() >>> d2 == d True >>> d2 {'a': 1, 'b': 2} >>> Now : it's not the first time - in a couple days - that you ask a question that you wouldn't have asked if you had taken a couple minutes doing the tutorial and/or reading the doc. This newsgroup is *very* tolerant (in most other places on usenet, you would have get a raw RTFM on the first question, and a PLONK on the second), but there are still limits, and as far as I'm concerned you're not far from them. So do yourself and the world a favour, read this: http://catb.org/~esr/faqs/smart-questions.html and then this: http://docs.python.org/tut/tut.html and next time someone points you to a specific module, have mercy and *read* the doc before posting. As far as I'm concerned, I won't anwser any of your questions unless it's obvious that you have followed these advices (but then I'll be happy to help if I can). -- http://mail.python.org/mailman/listinfo/python-list
