dictionary to file

[Enrique Palomo Jiménez]

Hi all,

I'm writing an application who needs to handle a lot of information of several files.
So, i think the better way is design a batch process to catch that information in a dictionary and write it in a file.
So, after that when a user wants to retrieve something, only with an execfile i'll have all the information avaiable.

Creating the file with pythonic syntax will be a hard job so,

is there some module to do that?
is there a better way?

The information will be used no more than 3-4 days a month and install databases is not allowed.

Thanks

You can easily pickle a dictionary and save that to a file.

You don't define what you mean by "a lot". Python can read
a tremendous amount of information from files in a very short
amount of time so I wouldn't try to prematurely optimize this.
Just read the information and see how long it takes. If it
is really a long time, then look for alternatives. It will
take some time to read the dictionary and to unpickle it.
