Using %f with strftime() in Python to get microseconds

Question

I\'m trying to use strftime() to microsecond precision, which seems possible using %f (as stated here). However when I try the following code:

import time
im         


        

Answer 1

If you want an integer, try this code:

import datetime
print(datetime.datetime.now().strftime("%s%f")[:13])

Output:

1545474382803

Answer 2

If you want speed, try this:

def _timestamp(prec=0):
    t = time.time()
    s = time.strftime("%H:%M:%S", time.localtime(t))
    if prec > 0:
        s += ("%.9f" % (t % 1,))[1:2+prec]
    return s

Where prec is precision -- how many decimal places you want. Please note that the function does not have issues with leading zeros in fractional part like some other solutions presented here.
