I'm not sure how to approach this one

It looks like it wants me to combine them? So just add them together? I'm a little confused on this challenge

timestrings.py
## Examples
# to_string(datetime_object) => "24 September 2012"
# from_string("09/24/12 18:30", "%m/%d/%y %H:%M") => datetime

import datetime
def to_string(foo):
  return foo.strftime('%d %B %Y')

def from_string(arg_str,arg_strftime):

No, you don't want to combine the arguments. Instead, pass them to the strptime function which will use them to create a new date.

If you re-watch the Wikipedia Links video, you'll see an example where this is done around time index 2:20.

I passed it with this code, but I'm still not entirely sure how it can work with a string? I thought strings cannot be read the same way.

## Examples
# to_string(datetime_object) => "24 September 2012"
# from_string("09/24/12 18:30", "%m/%d/%y %H:%M") => datetime

import datetime
def to_string(foo):
  return foo.strftime('%d %B %Y')

def from_string(arg_str,arg_strftime):
  date = datetime.datetime.strptime(arg_str,arg_strftime)
  return date
