Python: How to convert elapsed seconds to H:M:S format

Question

I have this code:

start = time.time()

# some code here that doesn't have anything to do with the question

end = time.time()

time_result = int(end - start)

The time_result variable is the number of seconds it took to finish running the code. How would I convert this to a '00:00:00' string (hours, minutes and seconds)?

Answer 1

IIUC: To convert the number of elapsed seconds to a string such as 00:00:23:

import time
from datetime import datetime as dt

start = time.time()
elapsed = time.time() - start

# Edited to use UTC.
output = dt.strftime(dt.utcfromtimestamp(elapsed), '%H:%M:%S')

>>> '00:00:23'

Other formatting strings can be found here in the datetime docs.
