Where do I go from here?

I've tried a couple of things, like writing Paris = but couldn't pass the challenge. Where do I go from the start of the challenge?

aware.py 
import datetime

naive = datetime.datetime(2015, 10, 21, 4, 29) 
timezone = datetime.timedelta(hours=-8) 
hill_valley = datetime.datetime(2015, 10, 21, 4, 29, tzinfo=datetime.timezone(datetime.timedelta(hours=-8)))

Here's the solution to the problem:

import datetime

pacific = datetime.timezone(datetime.timedelta(hours=-8))
europe = datetime.timezone(datetime.timedelta(hours=+1))

naive = datetime.datetime(2015, 10, 21, 4, 29)

hill_valley = datetime.datetime(2015, 10, 21, 4, 29, tzinfo=pacific)
paris = hill_valley.astimezone(europe)

I think you can see how it works :P

Rethinking my answer (and this one):

# help(datetime.datetime.replace)
# replace(...)
#    Return datetime with new specified fields.

# hill_valley should be derived from naive and not recreated from scratch:

hill_valley = naive.replace(tzinfo=pacific)
