How to sum find the average of several datetime

I am wondering how to find the average of the several datetimes. For example, I have the following datetime list:

a=[datetime.datetime(2010, 10, 14, 0, 14), datetime.datetime(2010, 10, 14, 0, 15), datetime.datetime(2010, 10, 14, 0, 16), datetime.datetime(2010, 10, 14, 0, 17)]

When I trying to add them up directly, it tells me that there is a

TypeError: unsupported operand type(s) for +: 'int' and 'datetime.datetime'

Not sure what is the correct way of doing this.

Very appreciated if you could help me out!

Thank you!

technically, you can calculate the "average" of your datetimes by casting their mean timestamp (UNIX time) to a new datetime object:

import datetime

l = [datetime.datetime(2010, 10, 14, 0, 14), 
     datetime.datetime(2010, 10, 14, 0, 15),
     datetime.datetime(2010, 10, 14, 0, 16), 
     datetime.datetime(2010, 10, 14, 0, 17)]

middle = datetime.datetime.fromtimestamp(sum(d.timestamp() for d in l)/len(l))

# middle
# datetime.datetime(2010, 10, 14, 0, 15, 30)
