Challenge Task timezone.py

What is wrong with my code?

Return(starter) didn't work either...

import datetime

import pytz

def to_timezone(timezone_string):
    starter = pytz.utc.localize(datetime.datetime(2015, 10, 21, 23, 29))
    starter = starter.astimezone(tz=pytz.timezone(timezone_string))
    starter_string = starter.strftime('%y-%m-%d %H:%M')
    starter_datetime = datetime.datetime.strptime(starter_string, '%y-%m-%d %H:%M')

Hi Steven,

Thanks! I was close enough to justify this 'Spoiler Alert'... :-)

Looks like you're overthinking this one. You nearly had it with just one of your lines. Here's some hints:

  • There's a function that converts a localized time to another zone, using a timezone object.
  • There's another function that converts a string into a timezone object.
  • If you combine these functions, you can get the converted time with a one-liner
  • starter is defined for you as a global variable, you won't need to define it inside your function
  • For the challenge, you only define your to_timezione function, you don't call it yourself

Can you do it now with just the hints?

If not...


def to_timezone(timezone_string):
    return starter.astimezone(pytz.timezone(timezone_string))
