Python Dates and Times in Python (2014) Dates and Times Timedelta Minute

I need help with the timedelta minute challenge

I do not understand why this doesn't work. Can somebody please help me here. Thank you in advance.

minutes.py
import datetime

def minutes(datetime1, datetime2):
    difference_sec = datetime2.total_seconds() - datetime1.total_seconds()
    difference_min = difference_sec / 60
    return round.difference_min

A "datetime" doesn't have a "total_seconds" method. But if you subtract one "datetime" from another, the result will be a "timedelta", and those do have such a method.

Also, "round" is a function; and when you call a function you write its name and then a pair of parentheses where you can place any arguments being passed to it.

Of course! Thank you. It all makes sense now :)
