Re: [Tutor] Re: Fw: Please submit to tutor list: dictionary update prob
Just one question... Why are you off the list? I see no point. If you want to stop getting the mail, you can change the options of your list account online... That's the only reason I see... Let's see -- reasons 1. Cost -- No, it's free 2. Security -- If you were subscribed to it once, it's too late to worry about that (Though there is no reason to) a. There is an option (in Outlook Express at least) to make your name invisible to others when emailing b. You can make your name invisible on the subscriber's list on the website by using the options in your account page Anyone want to comment -- maybe a link to get him to the subscriber's option page?

The absence of 'newdic' in the code after 'read.close()' should be a clue :-) Check the docs on pickle.dump() (which is the same as cPickle.dump()): dump( obj, file[, protocol[, bin]]) Write a pickled representation of obj to the open file object file. This is equivalent to Pickler(file, protocol, bin).dump(obj). So to pickle newdic you should say cPickle.dump(newdic, write) write.close() but it 'overwrites' the saved dic. can you rw in one go, dump and load the updated dict instantly?? I think you want to overwrite the saved dict, but with the new dict instead of with a filename string... Kent sending this in gmane mail2news gateway.
