Milliseconds with strftime

JoeBorgione — Fri, 10 Dec 2021 22:50:44 GMT

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...)

from datetime import datetime
curr_time = datetime.now()
formatted_time = curr_time.strftime('%H:%M:%S.%f')
print(formatted_time)

No way to take out the colons and period without a split and join back together?

edited: just take them out:

from datetime import datetime
curr_time = datetime.now()
formatted_time = curr_time.strftime('%H%M%S%f')
print(formatted_time)
