name 'timedelta' is not defined. Any hints? Help appreciated

i imported the library, so i'm not sure why it doesn't accept what i gave it.

minutes.py 
import datetime
def minutes(datetime_1,datetime_2):
    seconds_1 = timedelta.totalseconds(datetime_1)
    seconds_2 = timedelta.totalseconds(datetime_2)
    return round((seconds_2 - seconds_1) / 60)

where did you get the value 5 from?

5 was absolutely arbitrary; sorry for any confusion.

Two options for importing:

Option 1 (recommended): import the entire datetime module requires explicit datetime.timedelta below

 import datetime
def minutes(datetime_1,datetime_2):
    seconds_1 = datetime.timedelta.seconds(datetime_1)
...

Option 2: from the datetime module, importing only the timedelta class then timedelta on its own will work

from datetime import timedelta
def minutes(datetime_1,datetime_2):
    seconds_1 = timedelta.seconds(datetime_1)
...

Either way, seconds is a necessary attribute name, and totalseconds will not work.

Hi Jason,

I think I found the problem:

import datetime
seconds_1 = datetime.timedelta(seconds=5)

datetime is the module that contains the class timedelta. timedelta receives a parameter named seconds (among others)

You can see the docs here.
