It just doesn't make sense!

I just can't seem to pass this challenge. Can you help me?

pytzstring.py 
import datetime

fmt = '%m-%d %H:%M %Z%z'
starter = datetime.datetime(2015, 10, 21, 4, 29)
def to_timezone(new_timezone):
  # generate timezone from string
  new_tz = pytz.timezone(new_timezone) 
  # convert starter to new datetime
  new_dt = starter.astimezone(new_tz) 
  # Return new datetime object
  local = new_dt
  return local

You should not create a function for this challenge.

For Task 1 you need:

import datetime
import pytz

fmt = '%m-%d %H:%M %Z%z'
starter = datetime.datetime(2015, 10, 21, 4, 29)

pacific = pytz.timezone('US/Pacific')
local = pacific.localize(starter)

Loh Pin Hua could you specify a little bit, what you don't get?

Did you already read the docs? https://pythonhosted.org//pytz/

I don't think you can use astimezone on a naive datetime. Instead, use localize on a pytz timezone object and pass the naive datetime to it.

You might also need to import pytz first.

From the pytz docs:

from datetime import datetime, timedelta
>>> from pytz import timezone
>>> import pytz
...
>>> eastern = timezone('US/Eastern')
...
>>> loc_dt = eastern.localize(datetime(2002, 10, 27, 6, 0, 0))
>>> print(loc_dt.strftime(fmt))
2002-10-27 06:00:00 EST-0500

I still don't get it.
