Using the time in python

[Harry_77]

i was just wondering how i can use use the time to trigger something to happen.
for example, i have a raspberry pi and i programmed 2 LEDs to come on when i press a button in python. How could i programme it so they come on at 8:00AM for example?

The typical way to implement something like this is to calculate the time between now and the desired time. Set a timer to wakeup the process, then put the process to sleep. With this implementation you don't use CPU cycles while "waiting".
