To have data still available next time you run the program, you need to
write it to a file.

outfile = open("statefile.txt", "w")
outfile.write("Monday")
outfile.close()

Naturally, if you store non-trivial data, you'll have to organize it
somehow, so you can parse it when you read it back in.

Alternatively, you can use a module like configparser:

http://docs.python.org/3.3/library/configparser.html#module-configparser

or several other alternatives.
