[Tutor] Does Python have any callback function?

[Carlos Daniel Ruvalcaba Valenzuela]

That depends very much on how you are running both scripts in
parallel, if you are using Threads or process.

If using threads you can share a variable or object between the
scripts read it on A to check for updates and lock and update on B
(using semaphores for examples), there is an Event object on the
threading module but i have never used it.

If you are using process (via system call or something like that, not
threading) then you need an IPC mechanism, like sockets, signals or
RPC.

There is many ways to approach this problem really, these are just my
2 cents :-).

Good luck.
