Hi,

There are two task here: as You wrote, firstly log must be written to files

You could use the logging subsystem for this purpose
https://docs.python.org/3/library/logging.html

The second is to collect it and do someting.
To do this You can use for example the scedule module
https://docs.python.org/3/library/sched.html

BR,
George
