How to correctly parse the reminder date/time from the string (Tomorrow/every Tue/at 14:00)?

Question

Python

I am not a professional developer, programming is a hobby for me. Just for fun, I'm writing a reminder that takes a string.
Accordingly, from this line it parses the reminder text and, in fact, when to remind about it.
I would like the input to be as flexible as possible, i.e. not just a specific date time, but options like:
Every Tuesday at 14:00 for a massage
To a driving school the day after tomorrow at 19:00
On weekdays at 17:00 check the
report I quickly get confused.
So I thought, maybe everything has already been written before me and somewhere you can see how the rules do it. boys?

Answer 1

yes, the boys have already come up with everything for a long time

Answer 2

An example of a command parser for a robot ( F#, Dmitry Soshnikov ).
