python datetime to float with millisecond precision [duplicate]

Answer 1

Python 2:

def datetime_to_float(d):
    epoch = datetime.datetime.utcfromtimestamp(0)
    total_seconds =  (d - epoch).total_seconds()
    # total_seconds will be in decimals (millisecond precision)
    return total_seconds

def float_to_datetime(fl):
    return datetime.datetime.fromtimestamp(fl)

---

Python 3:

def datetime_to_float(d):
    return d.timestamp()

The python 3 version of float_to_datetime will be no different from the python 2 version above.
