Code works in workspaces, not in challenge

I have run the code in workspaces multiple times and it works. I put it in the challenge and it no longer works. all it says is "Bummer! Try again!" I don't know what to do. any help will be appreciated.

minutes.py
import datetime

def minutes(date1, date2):
    seconds1 = date1.total_seconds()
    seconds2 = date2.total_seconds()

    difference = seconds2 - seconds1
    seconds = difference/60

    return round(seconds)

:warning: Be careful about testing a challenge in workspaces or an external REPL.

If you have misunderstood the challenge, it's also very likely that you will misinterpret the results.

I'm guessing that your code seemed to work because you were passing it timedelta arguments, but the challenge says the function should receive datetime arguments. You'll need to make a few changes to handle the correct type of argument.

Hint: Remember that subtracting one datetime from another will produce a timedelta.

Ok. Thanks. This will be very helpful for future challenges. Thanks.

also, quick question, do you know of a way to turn a datetime into a timedelta?

I know a way to turn two datetimes into a timedelta (see my hint above).

But it doesn't make sense conceptually to convert just one - in what situation would you want to do that?

I don't exactly know. I was thinking that I would turn both datetimes into timedeltas and then subtract and do the total_seconds.

You have the right idea but the wrong order. What I was hinting at before is that if you subtract the first datetime from the second one, the result is a timedelta. Then you can take the total_seconds of that.

I realized that after I completed the challenge another way.

Below worked for me

 from datetime import timedelta


def minutes(time_one, time_two):
    difference = timedelta.total_seconds(time_two - time_one)
    delta_time = round(difference/60)
    return delta_time
