Milliseconds with strftime

Question

I need to return time to the millisecond;Python strftime reference provides the %f format place holder, but when I use it in Python 3.x it fails. This works: from time import strftime site = 'FP 20180822' for i in range(1,10): theTime = strftime("%H%M%S") newTime = '{} {}'.format(site,theTime) print('{}'.format(newTime)) #and returns: FP 20180822 162325 FP 20180822 162325 FP 20180822 162325 FP 20180822 162325 FP 20180822 162325 FP 20180822 162325 FP 20180822 162325 FP 20180822 162325 FP 20180822 162325 #the following fails with Invalid format String. #Note the %f which allegedly provides milliseonds from time import strftime site = 'FP 20180822' for i in range(1,10): theTime = strftime("%H%M%S%f") #### %f newTime = '{} {}'.format(site,theTime) print('{}'.format(newTime)) ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ I was hoping that spinning it through a loop would get me down to the millisecond. Any thoughts? (I can appended i at the end of new Time as a phony millisecond...)
