How can I make my function run at a specific time?

Question

Python

I need my function to start at exactly 16:00.

Answer 1

You can do it via schedule, read how to use it, it's incredibly easy to implement.
Or you can do it through the datetime check, almost the same as option 1, but easier.
One minus of all this - the script must be enabled on a permanent basis, or use the option from 1 answer.

Answer 2

There is one dumb way to
create a main.pyw file

def your_func():
    pass

import datetime

now = datetime.datetime.now()

while True:
    if(now.strftime("%H:%M")=="16:00"):
        your_func()
