Nothing in Python objects is persistent.  If you want something to 
survive till the next run, you have to write it to something external, 
such as a file.

If this is a serious program, with important passwords, you'll want to 
encrypt the file.  If it's just casual, encode the file in some obscure 
way.  But if it's a class assignment, then save it in a text file, in a 
directory you'll be able to find next time.

That last point is important.  The program directory may be read-only to 
that user.  So you might not be able to store it there.  One approach is 
to save it in the user's home directory,    so for me, it might be   
/home/davea    Convention is to start it with a leading period, so that 
the ls command won't show it by default.  Another question is whether 
you want a different password per user, and if you might have more than 
one user logged into your machine at the same time.

Hope this helped,
