This is my code for the time tango challenge and it seems like it should return a datetime object; but, it is not passing.
import datetime
def time_tango(date, time):
formatStr = "{} {}".format(date, time)
return datetime.datetime.strptime(formatStr, "%m/%d/%Y %I:%M:%S")

Treehouse Guest TeacherYou have a time object and a date object. Neither one will just turn into the string that you're expecting on their own (that's why strftime exists), but there's an easier way that I covered in the video. A method named combine().

def time_tango(d, t):
dt = datetime.datetime.combine(d, t)
dt = dt.strftime("%m/%d/%y %H:%M")
return datetime.datetime.strptime(dt, "%m/%d/%y %H:%M")
Still struggling with this one. Tried recreating this locally with what I assumed the variables were that you were passing in:
import datetime
today = datetime.datetime.today()
date = today.date()
time = today.time()
def time_tango(d, t):
dt = datetime.datetime.combine(d, t)
dt = dt.strftime("%m/%d/%y %H:%M")
return datetime.datetime.strptime(dt, "%m/%d/%y %H:%M")
print(time_tango(date, time))
Returns:
2014-11-17 15:20:00
And I get what I think is the desired result. It would be helpful to clarify whether "date" and "time" are datetime objects or strings, and in what format the output should be. The challenge specifies the output should be a datetime, but you suggest using the combine method, which requires the "date" and "time" to be strings. Here's what I get if "date" and "time" are strings:
import datetime
date = "11/17/14"
time = "3:15:00"
def time_tango(d, t):
return datetime.datetime.strptime(d + " " + t, "%m/%d/%y %H:%M:%S")
print(time_tango(date, time))
Returns:
2014-11-17 03:15:00
Neither approach passes the challenge, so I must be overlooking something obvious. A nudge in the right direction would be greatly appreciated.

Treehouse Moderator 48,850 PointsI had a similar problem. Forget about strptime and strftime for this challenge. The only method you need is datetime.datetime.combine(). Kenneth provided a link to the documentation above, if you need to look into the combine() method further.

Treehouse Guest TeacherI'm gonna make the prompt a bit more obvious for this one. It's obviously not obvious (hah) enough.
