x = (input("month: "), input("day: "), input("Year: "))
month: 11 day: 1 Year: 2016 ('11', '11', '2016') <---- how can I convert this in to this 11/01/2016 format?
You don't need the functionalities of the datetime module, you can simply go:
>>> x = input("month: ") + '/' + input("day: ") + '/' + input("year: ")
month: 11
day: 01
year: 2016
>>> x
'11/01/2016'
If you want to make it look pretty and pythonic:
>>> x = "%s/%s/%s" % (input("month: "), input("day: "), input("year: "))
month: 11
day: 01
year: 2016
>>> x
'11/01/2016'
Datetime won't help you here, as it's formatting applies mostly to time math.
"/".join(x)to connect the tuple to one string, or you could feed the month/day/year into Python's datetime library.
