Using a database would seem to meet a lot of your needs. Don't forget that 
Python comes with a sqlite database engine included, so it shouldn't take 
you more than a few lines of code to open the database once and then write 
out your status every few seconds.

import sqlite3

con = sqlite3.connect('status.db')

...
with con:
    cur = con.cursor()
    cur.execute('UPDATE ...', ...)

and similar code to restore the status or create required tables on 
startup.
