My problem is when I reload my web page the variable are set to their default value. How can I do to make this variable persistent on open/close connection? Vincent

Every connection spins another copy of your python program. In order to save anything between them you need some sort of storage. This could be as simple as small local file or as complex as external database (memcached/redis/dynamodb/mysql - your call)

I don't know much about python but according to docs it can do mmap too: https://docs.python.org/3/library/mmap.html could be interesting choice if you are on system that supports it.
