Python: timedelta-minute challenge

I don't know what am i doing wrong? Can you help me, please?

The challenge task is this one:

Write a function named minutes that takes two datetimes and, using timedelta.total_seconds() to get the number of seconds, returns the number of minutes, rounded, between them. The first will always be older and the second newer. You'll need to subtract the first from the second.

minutes.py 
from datetime import timedelta

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

I am new, but datetime has no method total_seconds() ??. datetimes can be added or subtracted - tricky part is then expressing what you want - hours, days etc etc. I think the below shoud work for def minutes.

return (datetime2 - datetime1)/timedelta(minutes=1)

Hello,

Thank you Michael for taking from your time to answer my question. I managed to complete the challenge without the total_second() function. I just substracted datetime2 from datetime1, then the result divided by 60, and the last step was to return the rounded total. Your solution is also good.

Have a good day!
