I ran into a problem today where I had to determine the mean point between two datetimes. Here is an example: >>> start = datetime.datetime(2016,2,11) >>> stop = datetime.datetime.now() >>> mean = start + (stop-start)*0.5 Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unsupported operand type(s) for *: 'datetime.timedelta' and 'float' A workaround could be something like this: >>> start + datetime.timedelta(seconds=0.5*((stop-start).total_seconds())) datetime.datetime(2016, 2, 11, 5, 45, 45, 818009) Interesting thing is that total_seconds() already returns fractions of seconds, so it would be almost trivial to implement timedelta multiplication with floats. I have checked and it does work with Python 3. But it does not work with Python 2 - is there a good reason for this? Thanks, Laszlo
