Python Dates and Times in Python Where on Earth do Timezones Make Sense? Datetime Awareness

Now make a variable paris that is hill_valley as the "Europe/Paris" timezone. "Europe/Paris" is UTC+01:00.

I'm trying to use the replace method, but cannot find the proper syntax after looking through the documentation...

import datetime

naive = datetime.datetime(2015, 10, 21, 4, 29)
pacific = datetime.timezone(datetime.timedelta(hours=-8))
hill_valley = datetime.datetime(2015, 10, 21, 4, 29, tzinfo=pacific)
Europe_Paris = datetime.timezone(datetime.timedelta(hours=1))
paris = hill_valley.replace(aware.astimezone(Europe_Paris)
aware.py
import datetime

naive = datetime.datetime(2015, 10, 21, 4, 29)
pacific = datetime.timezone(datetime.timedelta(hours=-8))
hill_valley = datetime.datetime(2015, 10, 21, 4, 29, tzinfo=pacific)
Europe_Paris = datetime.timezone(datetime.timedelta(hours=1))
paris = hill_valley.replace

You need to convert it to a new timezone. That means using astimezone() not replace().

Very confusing answer (sorry)

Based on your answer I thought this would work (but it does not):

paris = hill_valley.astimezone()

Fortunately I found this forum post that was more helpful:

Sorry that telling you the right method wasn't enough to get you on the right path. I try not to give the whole answer away.

So close!

paris is using the time of hill_valley as its base, but we are applying some other timezone to it. Therefore, it may make sense to pass some information into the astimezone() method.

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)

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)

Awersome i figured it out this way
