You can't compare a specific point in time (such as "right now") against an unfixed, recurring event (8am happens every day).
You can check if now is before or after today's 8am:
>>> import datetime
>>> now = datetime.datetime.now()
>>> today8am = now.replace(hour=8, minute=0, second=0, microsecond=0)
>>> now < today8am
True
>>> now == today8am
False
>>> now > today8am
False
