Okay, I don't know what i'm doing wrong.
Question: Write a function named minutes that takes two datetimes and 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.
import datetime
def minutes(datetime1, datetime2):
difference = datetime2 - datetime1
rounded = difference.round()
return rounded

seconds = dt2.timestamp() - dt1.timestamp()
return round(seconds / 60)

It is actually simpler than it appears you are thinking about it.
When you do the subtraction between the two datetimes (number2-number1 as u did), you get something like 00:10:00
Where 10 are the minutes. When I did the exercise I thought there was something built in the library to go from that to the minutes themselves, but I haven't found it so I have used .seconds to get the seconds and then divided by 60.
This is the code I wrote for this:
import datetime
def minutes(datetime1, datetime2):
return (datetime2-datetime1).seconds/60
Hope that helps.

Treehouse Guest TeacherThere's nothing to get minutes, only days, seconds, microseconds...
And you should have to use round() in there because the challenge expects an int, not a float (and division always produces a float in Python 3).

66,191 PointsHey this seemed to work for me:
import datetime
def minutes(datetime1, datetime2):
return int((datetime2-datetime1).seconds/60)

2,825 PointsMy code couldn't work until i considered to add 1 after the whole int function on return.
Guess it's because our python starts from 0, so it would give a second less than one to the required value.
LIKE THIS return int((datetime2-datetime1).seconds/60) +1
Kenneth Love
Treehouse Guest TeacherYou have to add the 1 because you're not rounding the result of the division like I told you to in the instructions.

2,825 PointsHahaha i just did
return round((date2-date1).seconds/60)
Thank you, i overlooked that part and thought i could get away with adding 1

3,852 PointsHello! I am getting the minutes difference when I try my code in iPython, but the challenge keep saying:
Bummer! Got the wrong number of minutes. Expected 7, got -53.
This is my code:
import datetime
dt1 = datetime.datetime.now()
dt1m = dt1.replace(hour= 8, minute = 30)
dt2 = datetime.datetime.now()
dt2m = dt2.replace(hour= 10, minute = 45)
def minutes(dt1m, dt2m):
res = round(dt2m.minute - dt1m.minute)
return int(res)
Am I missing something?
Kenneth Love
Treehouse Guest TeacherConsider this. I start with 5:55pm (1755) and 3:00am (0300). I subtract the minutes from each other and I get 55.
Are there only 55 minutes between those two times? What if they're days apart, too?
You need to get the minutes from the timedelta that you get from subtracting one datetime from another. timedelta doesn't have a minutes attribute, though, so you'll have to figure out how to make minutes from seconds.

import datetime
def minutes(datetime1, datetime2):
return round((datetime2-datetime1).seconds/60)
