Python Dates and Times in Python (2014) Where on Earth do Timezones Make Sense? Datetime Awareness

The error I am encountering for this part`paris` has the same date and time as `hill_valley`. Did you convert timezones?

import datetime

naive = datetime.datetime(2015, 10, 21, 4, 29) print(naive) pacific = datetime.timezone(datetime.timedelta(hours = -8)) europe = datetime.timezone(datetime.timedelta(hours = 1)) yy = int(naive.year) mo = int(naive.month) dd = int(naive.day)

hh = int(naive.hour)

mm = int(naive.minute) hill_valley = datetime.datetime(yy, mo, dd, hh, mm, tzinfo=pacific)

import pdb; pdb.set_trace()

paris = hill_valley.replace(tzinfo=europe) print('hill_valley: {}'.format(hill_valley))

print('paris: {}'.format(paris))

output:

hill_valley: 2015-10-21 04:29:00-08:00 paris: 2015-10-21 04:29:00+01:00 It shows the time is being changed with the timezone.

aware.py 
import datetime


naive = datetime.datetime(2015, 10, 21, 4, 29)
print(naive)
pacific = datetime.timezone(datetime.timedelta(hours = -8))
europe = datetime.timezone(datetime.timedelta(hours = 1))
yy = int(naive.year)
mo = int(naive.month)
dd = int(naive.day)

hh = int(naive.hour)

mm = int(naive.minute)
hill_valley = datetime.datetime(yy, mo, dd, hh, mm, tzinfo=pacific)
#import pdb; pdb.set_trace()

paris = hill_valley.replace(tzinfo=europe)
print('hill_valley: {}'.format(hill_valley))

print('paris: {}'.format(paris))

Hello, Vashra!

This code works:

import datetime

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

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

hill_valley = datetime.datetime(naive.year, naive.month, naive.day, naive.hour, naive.minute, tzinfo=pacific)

paris = hill_valley.astimezone(europe)
