Python Dates and Times in Python (2014) Dates and Times strftime & strptime

Posted by ks13

Create a new function named from_string that takes two arguments: a date as a string and an strftime-compatible format.

I have been trying to find help for this challenge but I just don't see what's the problem here.

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(datetime):
    datetime = datetime.strftime('%d %B %Y')
    return datetime

def from_string(date_object, datetimes):
    date_object = datetime.datetime.strptime(date_object, '%d %B %Y')
    return datetimes

I see two issues here:

The challenge tells you that one of the arguments being passed in will be a format string, but it is not being used in the conversion by this code and a fixed format string is being used instead.

And after performing the conversion, this code is returning one of the original arguments instead of the variable holding the conversion result.
