print some_object
first converts some_object to a string invoking str(some_object) which in
turn calls the some_object.__str__() method. The resulting string is then
written to stdout. Quoting the documentation:
datetime.__str__()
For a datetime instance d, str(d) is equivalent to d.isoformat(' ').
datetime.isoformat([sep])
Return a string representing the date and time in ISO 8601 format,
YYYY-MM-DDTHH:MM:SS.mmmmmm or, if microsecond is 0, YYYY-MM-DDTHH:MM:SS
