Is it possible to save changes to a list, dictionary etc without creating output file?
<p>I am currently making this python script for practice mostly, and I have set it up so that when a user enters a password they get redirected to another part of the script. My problem is that I want a feature to be able to change the password of the script and then keep the changes permanent. 
However is it possible to do this "in the script" without making it output to a txt file or to create any sort of file? I have looked into shelve, pickle, ConfigParser etc., but they all seem to create an output file, which is what I would like to avoid for security reasons.</p>

<p>If I <em>have</em> to output to a file, can I secure it in any way?</p>
