You've just overwritten the timedelta class in the datetime module! Do 
something like this instead:

     elapsed_time = end_time - start_time

>         print(datetime.timedelta)    #  works, prints 0:00:0.141000

>         print(datetime.timedelta.milliseconds)  # fails

     print (elapsed_time.microseconds / 1.0E6)
