Create a function named to_timezone that takes a timezone name as a string.

I get the following:

Bummer! to_timezone didn't return the right, converted datetime.

``

import datetime

import pytz fmt = '%Y-%m-%d %H:%M:%S %Z%z' utc= pytz.utc eastern = pytz.timezone('US/Eastern')

starter = pytz.utc.localize(datetime.datetime(2015, 10, 21, 23, 29)) starter_eastern = starter.astimezone(eastern) starter.strftime(fmt) def to_timezone(a_timezone): return starter_eastern

``

timezone.py 
import datetime

import pytz
fmt = '%Y-%m-%d %H:%M:%S %Z%z'
utc= pytz.utc
eastern = pytz.timezone('US/Eastern')

starter = pytz.utc.localize(datetime.datetime(2015, 10, 21, 23, 29))
starter_eastern = starter.astimezone(eastern)
starter.strftime(fmt)
def to_timezone(a_timezone):
  return starter_eastern

What they want you to do is take the argument a_timezone and us that to convert starter.

def to_timezone(a_timezone):
  return starter.astimezone([do something with a_timezone so that it can be used to convert starter.])

I hope you find this helpfull ^^

import datetime

import pytz

starter = pytz.utc.localize(datetime.datetime(2015, 10, 21, 23, 29))

def to_timezone(tz): timezone = pytz.timezone(tz) return starter.astimezone(timezone)

For this assignment, I would firstly recommend reading the link posted in the teacher's notes a couple of tasks back from here: http://www.saltycrane.com/blog/2009/05/converting-time-zones-datetime-objects-python/

Read the Convert time zones code and notice how she converts time zones.

HINT: Instead of starter.astimezone(eastern) , you may want to change this to something else.

Also, shouldn't you be making the adjustments to starter inside the function?

EDIT: In the link, she imports datetime and timezone straight from datetime and pytz, so make some adjustments in your code because of this. (I posted this as a comments instead first time oops)

Ok. Firstly, you need to Create a function named to_timezone that takes a timezone name as a string.. That means putting all the code to convert starter into a function called to_timzone.

Once that is done, you have made one tiny error: to_timezone = starter.astimezone(timezone('US/Pacific'))

When you set the timezone of starter to US/Pacific, timezone is not defined. This is because timezone belongs to the pytz module.

Summary: - create a function called to_timezone - alter you code so timezone is 'pulled out of' the pytz module.

I think that should solve it without giving too much away!
